I am currently using Asterisk 1.6.
Asterisk seems NOT to support incoming TEL connections from an IMS platform.
X-Lite does support this type of call without issue!
Is there any possibility that Asterisk could accept a TEL incoming connection?
Do we need a specific module?
This is currently the error we get: 404 Not Found
Here you find part of an (incoming) INVITE request.
CSeq: 1 INVITE
Using INVITE request as basis request -
Nov 13 17:52:05 NOTICE: chan_sip.c:6973 check_user_full: From address missing ‘sip:’, using it anyway
Nov 13 17:52:05 WARNING: chan_sip.c:6525 get_destination: Huh? Not a SIP header (tel:0987654321;phone-context=+32987654321)?
RDNIS is +3212345678
SIP/2.0 404 Not Found
It is strange that Asterisk seems to recognize the called number (see RDNIS); so why does it reject the call?
The basic problem seems to be that Asterisk only accepts SIP: in the From address and not TEL:
This way the incoming call is rejected!
