Usually in Asterisk PJSIP it can happen due to two things. Maximum number of seconds without receiving RTP (while on hold) before terminating call. Printed by Atlassian Confluence 5.6.6, Team Collaboration Software. Contacts specified will be called whenever referenced by chan_pjsip. The Asterisk Manager Interface (AMI) is a system monitoring and management interface provided by Asterisk. Asterisk WebRTC con PJSip desde Cero Rodrigo Cuadra August 20, 2021 1.- Introduccin WebRTC (Web Real-Time Communication) es un proyecto gratuito de cdigo abierto que proporciona navegadores web y aplicaciones mviles con comunicaciones en tiempo real (RTC) a travs de interfaces de programacin de aplicaciones (API) simples. When your (remote) phone is behind NAT, you may want to check the UDP timeout in your gateway and adjust the "maximum_expiration" time in your phone's AOR settings, like this: If your router/gateway/modem is a Linux device with default settings, the UDP "stream" timeout default is 180, so 160 is a safe setting for your phone to re-register. Time in fractional seconds. This is automatically produced by res_pjsip_outbound_registration. The interval at which unidentified requests are older than twice the unidentified_request_period are pruned. Note that this option is reserved for future functionality. Un-install and re-install Asterisk with no PJSIP related modules. Now, perhaps Asterisk is exposed on a public address, and instead your phones are remote and behind NAT, or maybe you have a double NAT scenario? Control whether dialog-info subscriptions get 'early' state on Ringing when already INUSE. This may result in a delay before an attack is recognized. Comma separated list of cipher names or numeric equivalents. This is a comma-delimited list of security mechanisms to use. Name of the RTP engine to use for channels created for this endpoint, Determines whether SIP REFER transfers are allowed for this endpoint, Determines whether a user=phone parameter is placed into the request URI if the user is determined to be a phone number, Determines whether hold and unhold will be passed through using re-INVITEs with recvonly and sendrecv to the remote side. Thanks in advance! IP-address of the last Via header from registration. Printed by Atlassian Confluence 5.6.6, Team Collaboration Software. lordaker March 15, 2018, 2:50pm #5 Ok, make this command so : /etc/init.d/asterisk restart That it ? With this option enabled, Asterisk will attempt to negotiate the use of the "rtcp-mux" attribute on all media streams. since I'm not able to organically reproduce the bug, to test it you can disable pjsip by hand: From FreePBX interface, open "Settings" > "Advanced Settings" find "SIP Channel Driver" variable and set it to "chan_sip" Submit and apply changes Now you should be able to verify the bug condition with grep pjsip /etc/asterisk/modules.conf The feature to enact when one-touch recording is turned on. This option must also be enabled in the system section for it to take effect here. On a heavily loaded system you may need to adjust the taskprocessor queue limits. If I set inband_progress = no in pjsip.conf, Asterisk will still send a Session Progress to the caller, which if I remember correctly corresponds to setting progressinband=no i sip.conf. If disabled it can improve realtime performance by reducing the number of database requests. A contact that cannot survive a restart/boot. Enforce that RTP must be symmetric. This option will be automatically enabled if webrtc is enabled and dtls_cert_file is not specified. Contacts are specified using a SIP URI. Use the defaults but keep oinly the first codec. This is a comma-delimited list of auth sections defined in pjsip.conf used to respond to outbound connection authentication challenges. A flaw in the IBM J9 VM class verifier allows untrusted code to disable the security manager and elevate its privileges. Enable STIR/SHAKEN support on this endpoint. set in pjsip.endpoint.conf. See link for more: http://www.openssl.org/docs/apps/ciphers.html#CIPHER\_SUITE\_NAMES. The priv_key_file option must supply a matching key file.

Allow subscriptions for the specified mailbox(es), Maximum number of contacts that can bind to an AoR. I think I get it now, thank you very much! FreePBX disabling modules for pjsip mrmrmrmr1 (Mekabe Remain) December 13, 2017, 9:01am #1 Hi, I am using both sip and pjsip extensions on my Asterisk setup. The feature to enact when one-touch recording is turned off. Codec negotiation prefs for incoming answers. This geolocation profile will be applied to all calls received by the channel driver from the remote endpoint before they're forwarded to the dialplan. If you are seeing messages like: Bridged Calls Direct media is not being used Inbound Registrations Outbound Registrations Inbound Subscriptions But sometimes FreePBX is disabling my pjsip modules at startup by modifying the modules.conf. I install Asterisk 13.19.2 on Ubutnu Server 16.04 LTS but all configuration is on sip.conf file. How can I configure static IP for chan_pjsip extensions? On receiving a new registration to the AoR should it remove enough existing contacts not added or updated by the registration to satisfy max_contacts? Set transaction timer T1 value (milliseconds). The feature designated here can be any built-in or dynamic feature defined in features.conf. Resolve the server_uri to an IP address and port, Send a REGISTER request to the IP address and port. /*]]>*/. The name of the endpoint this contact belongs to. Must be of type 'global' UNLESS the object name is 'global'. Many options for acceptable ciphers. [CDATA[*/ I reload the module in the Asterisk CLI too by this command : Noload only tells Asterisk at load time not to load chan_sip. Initial number of threads in the res_pjsip threadpool. Allow this transport to be reloaded when res_pjsip is reloaded. div.rbtoc1677948935580 li {margin-left: 0px;padding-left: 0px;} If specified, the extensions/patterns in the specified context will be used for determining if a full number has been received from the endpoint. div.rbtoc1677948935580 {padding: 0px;} Some UAs use OPTIONS requests like a 'ping' and the expectation is that they will return a 200 OK. The key is to make sure you have those three options set appropriately. Are you telling me that I am sending to the provider my IP so he can route the calls where I ask?I am still confused about the difference between the server_uri and client_uri A SIP REGISTER is for telling a remote server where you can be reached. You have Installed Asterisk including the res_pjsip and chan_pjsip modules (implying you installed their dependencies as well) You understand basic Asterisk concepts. It's explicitly configured. Minimum time to keep a peer with an explicit expiration. Contains several options and rules used for STIR/SHAKEN. The migration script is just that, a handy script to migrate if you have an existing sip.conf and dont want to start from scratch. keeping the order of the preferred list. IP-port of the last Via header from registration. If not specified, the context configured for the endpoint will be used. Direct Media 100rel/early media Re-invites Fax Multi-stream Certain SS7 internetworking scenarios can result in a 183 to be generated for reasons other than early media. More than one mailbox can be specified with a comma-delimited string. If not set, incoming MWI NOTIFYs are ignored. The mailboxes specified will be subscribed to. This option also helps reuse reliable transport connections such as TCP and TLS. This is a string that describes how the codecs specified in the topology that comes from the Asterisk core (pending) are reconciled with the codecs specified on an endpoint (configured) when sending an SDP offer. It depends on how the remote side is set up. Under certain conditions they could make things worse. When the number of seconds is reached the underlying channel is hung up. The feature designated here can be any built-in or dynamic feature defined in features.conf. However, to allow anonymous calls you need to create an endpoint named "anonymous" (or any of the variants listed below if the disable_multi_domain option is 'no') and load res_pjsip_endpoint_identifier_anonymous.so. If no subscribe_context is specified, then the context setting is used. type=endpoint. Separate the IP address and subnet mask with a slash ('/'). At the time of SDP creation, the IP address defined here will be used asthe media address for individual streams in the SDP. The following values are valid: This setting only describes whether the password is in plain text or has been pre-hashed with MD5. Where the public network is the Internet. If this option is set to uri_pjsip the redirect occurs within chan_pjsip itself and is not exposed to the core at all. Together these options make sure the far end knows where to send back SIP and RTP packets, and direct_media ensures Asterisk stays in the media path. The number of in-use channels which will cause busy to be returned as device state, Whether T.38 UDPTL support is enabled or not, How long into a call before fax_detect is disabled for the call, Whether NAT support is enabled on UDPTL sessions, Bind the UDPTL instance to the media_adress. 3. pkirkham January 29, 2019, 2:36pm 15 This is a string that describes how the codecs specified on an incoming SDP offer (pending) are reconciled with the codecs specified on an endpoint (configured) before being sent to the Asterisk core. The problem is my Asterisk is not sending OPTIONS to peers to qualify them. For this NAT example, the important config options to note are local_net, external_media_address and external_signaling_address in the transport type section and direct_media in the endpoint section. In old sip server, we were using the following command in AGI. This option does not apply to the ws or the wss protocols. MWI taskprocessor low water clear alert level. Preferences for selecting codecs for an outgoing call. There is a difference in meaning for an empty realm setting between inbound and outbound authentication uses. Some SIP phones (Mitel/Aastra, Snom) expect a sip/frag "200 OK" after REFER has been accepted. On incoming INVITEs, the Identity header will be checked for validity. The "none" and "pjsip_only" options should be used with extreme caution and only to mitigate specific issues. We are assuming you have already read the Configuring res_pjsip page and have a basic understanding of Asterisk. Enabling allow_unauthenticated_options will skip authentication of OPTIONS requests for the given endpoint. Number of seconds between RTP comfort noise keepalive packets. This option controls both how an endpoint is matched for incoming traffic and also how an AOR is determined if a registration occurs. The channel driver itself being chan_pjsip which depends on res_pjsip and its many associated modules. If Asterisk is already running you can unload chan_sip using module unload chan_sip.so from the console, but if it started before PJSIP then it would cause problems. Method for setting up Direct Media between endpoints. String placed as the username portion of an SDP origin (o=) line. I'm using chan_pjsip trunks so I'll try to find where to add the "session-timers=refuse" in the trunk configuration, or I'll change the trunk to chan_sip. Maximum session timer expiration period. Variable set on a channel involving the endpoint. There are several methods to disable or remove modules in Asterisk. The remove_existing option can help by removing the soonest to expire contact(s) over max_contacts which is likely the old rewrite_contact contact source address being refreshed. The IP-address of the last Via header is automatically stored based on data present in incoming SIP REGISTER requests and is not intended to be configured manually. Since Asterisk normally sends a security event when an incoming request can't be matched to an endpoint, using auth_username requires that the security event be deferred until a request is received with the Authentication header and only generated if the username doesn't result in a match. celsoannes August 21, 2019, 5:28pm #12 Thanks for the clarification. When enabled, aggregate_mwi condenses message waiting notifications from multiple mailboxes into a single NOTIFY. The value is a comma-delimited list of IP addresses. List of IP addresses to permit access from, List of Contact ACL section names in acl.conf, List of Contact header addresses to permit. Automatically enable the sending of responses to the source IP address and port, as though rport were present, if Asterisk detects NAT. This value does not affect the number of contacts that can be added with the "contact" option. Dialplan context to use for overlap dialing extension matching. When the initial unsolicited MWI notifications are disabled on startup then the notifications will start on the endpoint's next contact update. This option specifies which of the password style config options should be read when trying to authenticate an endpoint inbound request. If set to userpass then we'll read from the 'password' option. This geolocation profile will be applied to all calls received by the channel driver from the dialplan before they're forwarded the remote endpoint. If not specified, the global object's default_realm will be used. The string actually specifies 4 name:value pair parameters separated by commas. Protocol Behavior The router is performing Network Address Translation and Firewall functions. If no, private Caller-ID information will not be forwarded to the endpoint. Its safer to just restart Asterisk clean. When the number of seconds is reached the underlying channel is hung up. Using the same auth section for inbound and outbound authentication is not recommended. This option must also be enabled on endpoints that require this functionality. SIP/#######@sipserverip.com,30,HL (299940000:7000:5000) Whitespace is ignored and they may be specified in any order. Reference documentation for all configuration parameters is available on the wiki: You'll need to tweak details in pjsip.conf and on your SIP device (for example IP addresses and authentication credentials) to get it working with Asterisk. Time in seconds. Is there a way to accomplish this? Time to keep alive a contact. If specified, incoming MESSAGE requests will be routed to the indicated dialplan context. A -> Asterisk -> B after B send back 200 OK Asterisk is answering the call to A. The rewrite_contact option registers the source address as the contact address to help with NAT and reusing connection oriented transports such as TCP and TLS. This setting has no effect if the endpoint's one_touch_recording option is disabled. div.rbtoc1677948935580 ul {list-style: disc;margin-left: 0px;} There is nothing Asterisk or PJSIP specific about this really, as a REGISTER is a defined thing in SIP. The default input file is sip.conf, and the default output file is pjsip.conf. It is important to know that PJSIP syntax and configuration format is stricter than the older chan_sip driver. A path to a key file can be provided. Example: setting callerid_privacy to any prohib variation. On outgoing calls, if the UAS responds with different SDP attributes on subsequent 18X or 2XX responses (such as a port update) AND the To tag on the subsequent response is different than that on the previous one, follow it. Timer B determines the maximum amount of time to wait after sending an INVITE request before terminating the transaction. Prefer the codecs coming from the endpoint. Enables Path support for REGISTER requests and Route support for other requests. disable-video --disable-sound --disable-opencore-amr This command must be modified when using a 32-bit operating system. You can generate the hash with the following shell command: $ echo -n "myname:myrealm:mypassword" | md5sum. Only used when auth_type is md5. If set to yes T.38 UDPTL support will be enabled, and T.38 negotiation requests will be accepted and relayed. RFC 3261 says that the response to an OPTIONS request MUST be the same had the request been an INVITE. If you have multiple auth objects for an endpoint, the realm is also used to match the auth object to the realm the server sent. See link for more: http://www.openssl.org/docs/apps/ciphers.html#CIPHER\_STRINGS. @jcolp I install it by following the process in the wiki Asterisk and its work Thanks, Powered by Discourse, best viewed with JavaScript enabled, https://wiki.asterisk.org/wiki/display/AST/Configuring+res_pjsip. You can configure in pjsip.conf in the global section the "debug" option which will enable "pjsip set logger on" from the very start, causing SIP requests and responses to be output to the Asterisk console. Asterisk and the phones are on a private network. Valid options include yes, no, or a host address. Basically always send SIP responses back to the same port we received SIP requests from. The certificate file can be reloaded if the filename in configuration remains unchanged. These examples contain only the configuration required for sip.conf/pjsip.conf as the configuration for other files should be the same, excepting the Dial statements in your extensions.conf. On outgoing INVITEs, an Identity header will be added. Can be set to a comma separated list of numbers or ranges between the values of 0-63 (maximum of 64 groups). I'm not sure I got that right. At the specified interval, Asterisk will send an RTP comfort noise frame. If no message_context is specified, then the context setting is used. The interval (in seconds) to check for expired contacts. As an alternative to specifying a plain text password, you can hash the username, realm and password together one time and place the hash value here. If you like to figure out things as you go; here's a few quick steps to get you started. In various parts of PJSIP, when error/failure occurs, it is found that the function returns without releasing the currently held locks. Here we can show some examples of working configuration for Asterisk's SIP channel driver when Asterisk is behind NAT (Network Address Translation). However, only the certificate is read from the file, not the private key. Including the role of extensions.conf (dialplan) in your overall Asterisk configuration. In the above example we assumed the phone was on the same local network as Asterisk. This method has some security considerations because an Authentication header is not present on the first message of a dialog when digest authentication is used. Path support will also be indicated in the Supported header. As shown in picture, changing NAT = yes and IP Configuration to static in Settings > SIP Settings > Chan SIP Settings solved the issue for chain_sip extensions. For outgoing authentication (asterisk is the UAC), the realm must match what the server will be sending in their WWW-Authenticate header. It is not intended to work for every scenario or configuration; for basic configurations it should provide a good example of how to convert it over to pjsip.conf style config. Any removed contacts will expire the soonest. Asterisk 18 Module Configuration Asterisk 18 Configuration_res_pjsip Created by Wiki Bot, last modified on Jan 11, 2023 SIP Resource using PJProject This configuration documentation is for functionality provided by res_pjsip. It works by doing the following: While in many cases server_uri and client_uri could be the same, in some SIP environments they may be different. For more information on this timer, see RFC 3261, Section 17.1.1.1. This examples shows the configuration required for: This shows configuration for a SIP trunk as would typically be provided by an ITSP. This option enforces a limit on the maximum simultaneous negotiated video streams allowed for the endpoint. Some devices can't accept multiple Reason headers and get confused when both 'SIP' and 'Q.850' Reason headers are received. Stored Path vector for use in Route headers on outgoing requests. The other options may be different depending on how you want to use Asterisk. This option allows the 'Q.850' Reason header to be suppressed. Determines whether new contacts should replace unavailable ones. When disabled, a connected line update must wait for another reason to send a message with the connected line information to the caller before the call is answered. The core feature code transfer . Set transaction timer B value (milliseconds). Must be in the format Name
