Summary:ASTERISK-28175: PJSIP support for TEL (RFC 3966)

Description:Essentially set up pjsip.conf to register to ITSP and made an endpoint to receive incoming calls.

Unfortunately received response advising that TEL is unknown or at least not a ‘SIP’ URI, actual SIP error phrase is “416 Unsupported URI Scheme”.

Chan_SIP is RFC 3966 compliant from what I can see but i would like to use PJSIP because there are more features, and after trialing running both together the system is unreliable. My preference is to just use PJSIP.

I’m hoping someone whos awsome and a wizard with Asterisk can help me out with a configuration setting or advise if its possible to patch the source code for Asterisk 16.0.1 to permit the correct handling of a tel: uri invite.

I noticed the Wiki Bot identified PJSIP_PARSE_URI(uri,type)

Searching version 16.0.1 there is a lot of places where this is mentioned.   Can someone provide some guidance. Gaining an understanding the data structures and best debugging practices / scripts would be helpful too.

This is not the proper place for such discussion. The link I provided has information on the developer resources such as the mailing list and other things. Generally though you'll need to ask specific targeted questions.
