[SR-Users] Relaying ACK to Asterisk

Hello,

Any idea on how can I manage this? I'm still stuck in this issue.
If I remove the IP address from domain table, it works but many REGISTER
fails because the R-URI only contains sip:<IP_KAMAILIO/ASTERISK> without the
port.

Many thanks for your help.

Regards,

Igor.

Yes you're right. But many SIP requests come with R-URI
sip:<IP_KAMAILIO/ASTERISK> without the port.
So the test "is_from_local" fails.

Igor.

As I said before, what you need to use is IP_KAMAILIO/ASTERISK:5060.   
If you use it without the port, it will match also when directed to your
Asterisk server residing on the same IP and loop inside Kamalio without
being routed properly.
