Hi I am sending a request to kamailio server with tel uri as a part of request uri. I am getting "478 Unresolvable destination" from the server.

Please let me know what are the changes required to handle TEL URI in kamailio

Here is the request which i am sending to kamailio:

INVITE tel:229;phone-context=domain.com SIP/2.0

From: "228"<sip:228@domain.com>;tag=xxxxx

To: "229"<tel:229;phone-context=domain.com>

Thanks in advance

Regards

Raman
