P-Asserted-Identity: <tel:+256256xxxxxxx>

Hello,
I am tryinng INBOUD CALL for SIP based.

Everythig is fine, even outboud is working.

But when I try to make Incoming call it SNGREP shows me these two erros:

  1. SIP/2.0 416 Unsupported URI Scheme

  2. P-Asserted-Identity: tel:+256256xxxxxxx

It shows me that my telephone number is adding duplicate country code.

Please your help?

What version of Asterisk is in use? Are you using PJSIP? What is the actual complete INVITE request?
