Dial-Peer configs


I'm trying to exchange calls between 2 SIP proxies and and a cisco gateway (AS5300)
Let me first show you what what I'm trying to accomplish before I explain my problem


Calls are sent from proxy 1 to proxy 2 with prefix 2222
Calls are sent from proxy 2 to proxy 1 with prefix 1111
Proxy 1 and proxy 2 calls out to PSTN through the gateway with prefix 9999
proxy 1 and proxy 2 do NOT dial fixed length digits after the prefix, it always varies.

here are my dial peers settings:

dial-peer voice 1111 voip
destination-pattern 1111T
voice-class codec 10
session protocol sipv2
session target ipv4:
dtmf-relay rtp-nte
no vad
dial-peer voice 2222 voip
destination-pattern 2222T
voice-class codec 10
session protocol sipv2
session target ipv4:
dtmf-relay rtp-nte
no vad

dial-peer voice 100 pots
destination-pattern 9999T
no digit-strip
port 0:D

I'm sure I have Dial-peers not configured right but I cannot figure it out.
when SIP proxy 1 calls exten 2222175 at proxy 2 going through the AS5300, the  AS5300 returns (SIP/2.0 404 Not Found).  Any guidance on how I can  accomplish this task is really appreciated, I'm no cisco guy but I'm  under so much pressure

Hi Dave,

The dialpeers look correct. Although we need incoming peers too. For example:

dial-peer voice 100 voip

incoming called-number .

codec xx

Understanding Inbound and Outbound Dial Peers Matching:

When you call through the Access server like this it will be an IPIP call. Make sure you have:

voice service voip

allow-connection sip to sip

configure. And also I would not use voice class codec. It is not supported with IPIP gateway below the version 15.1(2)T. It might lead to codec mismatch. If after adding the commands which I have suggested the calls still does not work please collect:

debug ccsip messages

debug voice ccapi inout

from the AS5300 along with the dialpeer configuration.

Best regards,
