Hi, i need help to configure a sip trunk
i have a cisco 3825 with CME and recently bought a sip trunk with a local provider, but i cant get it works.. pls help
the provider said that The sip trunk dont have security, just this parameters to configure.
dir ip X.X.X.X Port 5060
its a openser no user no password.
so this is my sip configuration in the cisco router:
show run...
voice service voip
allow-connections sip to sip
allow-connections h323 to sip
allow-connections sip to h323
allow-connections h323 to h323
!
voice class codec 1
codec preference 1 g729br8
codec preference 2 g729r8
codec preference 3 g723ar63
codec preference 4 g711ulaw
codec preference 5 g711alaw
!
!
dial-peer voice 11 voip
destination-pattern T
voice-class codec 1
session protocol sipv2
session target ipv4:X.X.X.X
dtmf-relay rtp-nte
no vad
!
!
!
But when a called , just hear the busy tone...
and when i recive calls nothings happens
the router dont show any activity with the debug ccsip all, only when i make calls.
so pls, someone, what else have to do to configure ? something missing ?

If you're not getting debugs it means the SIP messages aren't processed by the router.
Three primary reasons for this:
1) You have SIP bound to an interface already in voice service voip, and that's not the interface they are sending to.
2) Your IP address on your router does not match what the provider is sending to
3) Provider has an issue routing calls. This could include something like a BGP problem where you're just not advertising it, or something like a call routing mistake on their side.
What does debug ccsip messages look like?

Hi,
you need to check the codec
i didnt see your codec
i think that you can make call, and the phone ring, but when you hang up, the call end, maybe this is the problem, or you have to check the rtp packets.

can you put the ephone and ephone-dn configure, because you can configure the codec on phone.
I think that is problem of codec, and i didnt see the transcoding
