SIP Trunk

Unanswered Question

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

h323

call start slow

sip

no call service stop

----


dial-peer voice 3 voip

destination-pattern ....

session protocol sipv2

session target ipv4:192.168.16.6

dtmf-relay rtp-nte

codec g711alaw

no vad



Thank you in advance

debug ccsip messages may be more informative of your problem.

looks like it could work. context is more important than configuration.
