[cisco-voip] SIP trunk to a CME router from a CUCM6 server

[Mark J]

Hey guys and girls,

I need some help setting up a SIP trunk to a CME router from a CUCM6 server.

I have followed the following guide (
http://www.voip-info.org/wiki/view/Asterisk+Cisco+CallManager+Integration)
to configure the CUCM6 and as far as I can see it's working as I'm able to
make calls the remote site.

The configuration on the remote router is as follows:

dial-peer voice 11 voip
 description Head Office
 translation-profile outgoing strip-to-3digext
 preference 5
 destination-pattern [1-4].
 session protocol sipv2
 session target ipv4:10.103.10.5
 dtmf-relay sip-notify
 codec g711ulaw
 no vad

The problem is that the remote site can not call Head Office, any ideas?

Thanks
