Strange issue with Voice Gateway

alexwzh · ‎03-13-2008

Currently I have a Voice Gateway on one of my sites that connects to a PABX via E1 connection. The Voice Gateway is then connected to the WAN with connects it to other remote sites.

The Voice Gateway has VOIP dial-peers configured that were meant to forward voice traffic to other remote sites. However, it seems that when we try to dial those numbers, it is coming up with a 'congestion' message on the phone. Also when you do a show call active voice brief, the following is the result ..

39F3 : 27409 948401910ms.2 +-1 pid:100 Originate 100555 connecting

dur 00:00:00 tx:0/0 rx:0/0

IP 0.0.0.0:0 SRTP: off rtt:0ms pl:0/0ms lost:0/0/0 delay:0/0/0ms g729r8 pre-ietf

media inactive detected:n media contrl rcvd:n/a timestamp:n/a

It keeps showing up as g729r8 pre-ietf even though I've not specified that in the configuration. Calls from other remote sites work with the same configuration.

Any ideas?

Hi,

Put the following commands in your local interface of remote voice gateway

interface FastEthernet0/0 --> Local Interface

h323-gateway voip interface

h323-gateway voip bind srcaddr

Also put the following commands on remote voice gateway

----------------------------------

voice call send-alert

voice call carrier capacity active

voice rtp send-recv

!

voice service voip

allow-connections h323 to h323

----------------------------------

Is the phone with the message connected to a call manager? Congestion is a message that displays only when CAC has rejected the call.

Have you properly configured locations for your dial plan?
