I am trying to configure SIP trunk between Cisco Unified Communication Server and 1861 router with SRST.
When I try to initiate a call through this trunk, I hear only beeps and call does not succeed. However, in debug voice dialpeer all I can see something going on, dont know exactly what it means, but I suppose SIP trunk does not go up.
Take a look at my SIP config on the router and let me know please what I am missing:
voice service voip
allow-connections sip to sip
no supplementary-service sip moved-temporarily
supplementary-service ringback h225-info
fax protocol cisco
call start slow
no call service stop
dial-peer voice 3 voip
session protocol sipv2
session target ipv4:192.168.16.6
Thank you in advance
