>             Project: Asterisk
>          Issue Type: New Feature
>      Security Level: None
>          Components: Resources/res_pjsip_session
>    Affects Versions: 16.0.0, 16.0.1
>         Environment: Ubuntu 18.0.1 LTS
>            Reporter: ast
>            Severity: Critical
>              Labels: pjsip
>
> 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.
