Codec Support One is codecs support, make sure you have specified codecs to be used and both sides can communicate on at least on available codec. Disable the use of rport in outgoing requests. There are still lots of things to implement and/or test. The other options may be different depending on how you want to use Asterisk. More than one mailbox can be specified with a comma-delimited string. When enabled the UDPTL stack will use IPv6. If media_address is specified, this option causes the RTP instance to be bound to the specified ip address which causes the packets to be sent from that address. Are both allowed? I'm not sure I got that right. If your UDP stream timeout is larger (/proc/sys/net/netfilter/nf_conntrack_udp_timeout_stream), you may adjust maximum_expiration accordingly. When the number of in-use channels for the endpoint matches the devicestate_busy_at setting the PJSIP channel driver will return busy as the device state instead of in use. If you like to figure out things as you go; here's a few quick steps to get you started. It can't be blank unless you expect the server to be sending a blank realm in the header. I recently migrated our old server to new Asterisk with PJSIP, we are using database and AGI to control calls. 3. This option will be automatically enabled if webrtc is enabled and dtls_cert_file is not specified. If remove_existing is set to yes, setting remove_unavailable to yes will prioritize unavailable contacts for removal instead of just removing the contact that expires the soonest. Use only the ones that are common. That native transfer functionality is independent of this core transfer functionality. 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. If you are wanting to use chan_pjsip alongside chan_sip, you could change the port or bind interface of your chan_pjsip transport in pjsip.conf, rtp_symmetric - Send media to the address and port from which Asterisk receives it, regardless of where SDP indicates that it should be sent, force_rport - Send responses to the source IP address and port as though port were present, even if it's not.

You can use it to turn a local computer or server to the communication server. On inbound SIP messages from this endpoint, the Contact header or an appropriate Record-Route header will be changed to have the source IP address and port. The con is that since redirection occurs within chan_pjsip redirecting information is not forwarded and redirection can not be prevented. Determines whether media may flow directly between endpoints. See the auth realm description for details. Disabling res_pjsip and chan_pjsip You may want to keep using chan_sip for a short time in Asterisk 12+ while you migrate to res_pjsip.

Asterisk Server name on which SIP endpoint registered. Codec negotiation prefs for incoming answers. 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. 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. Thanks in advance!

[CDATA[*/ Set transaction timer B value (milliseconds). The string actually specifies 4 name:value pair parameters separated by commas. Having a noload for the above modules should (at the moment of writing this) prevent any PJSIP related modules from loading. This example should apply for most simple NAT scenarios that meet the following criteria: This example was based on a configuration for the ITSP SIP.US and assuming you swap out the addresses and credentials for real ones, it should work for a SIP.US SIP account. Just remove the --libdir=/usr/lib64 option from the command. Now the packet capture shows how the media goes through the asterisk interface. A path to a key file can be provided.
