TEl URI on Asterisk

Asterisk Asterisk SIP
1

Hai Everyone,

I have an Asterisk Asterisk 16.16.2 server instaled on CentOS Linux release 7.9.2009 (Core). Having the SIP Trunk from Telecom operator which is working with chan_sip but the same is tested with chan_pjsip and with that am facing the issue of call disconnection.

As checked the SIP Trunk provided the SIP trunk TEL URI which is working with chan_sip but not with chan_pjsip and while calls getting disconnected from asterisk with SIP Response as SIP/2.0 416 Unsupported URI Scheme

Below are some of the pjsip logger logs. Whether Asterisk support TEL URI on PJSIP or it will work only with chan_sip ?

tel: is unsupported in chan_sip, and actively rejected in chan_pjsip. In both cases the reasoning is that a complete analysis of the code to determine whether these are safe in all contexts has not been performed.

@david551 - Thanks for the response.

Is it unsupported and still working with chan_sip ?

In this case, I have to ask my telecom vendor to change the URI from TEL to SIP right ?
