Reception of a tel URI

Asterisk Asterisk Support
1

Hello,

I installed an asterisk gateway equiped with a TE820 boad to perform the interworking between an IMS network and a PSTN network. The asterisk Gateway works fine when it receives from the IMS an INVITE with a SIP URI in the To and the Request URI Header. However when it receives from the IMS a Tel URI in the To and the Request URI Header, the asterisk Gateway rejects the call with a “SIP 416 Unsupported URI Scheme”.
Do I need to make a specific config in my extension.conf to support the reception of a Tel URI.

Thanks for your answer,
Sébastien Prouvost

You will need to change the sender to send SIP URIs.
