Re: Problems with E1 card an Lucent G3


Can You please tell me what IOS version you have on the 2600.

Also try adding the following commands

Voice Call Send-Alert

Voice rtp send-recv.

and also add in the Voip Dial Peer.

Progress_ind setup enable 3

Hope this Helps.

One More Thing that may help.

We experienced the same problems on our intial installations.

We had to point the Call Manager to Interface Loopback address.

The command is as follows

interface Loopback0

Ip interface

h323-gateway voip bind srcaddr

the Ip Address of this loopback interface will be the address of the Gateway in the Call Manager.

This should help your one-way audio problem

if not look in the Cisco site for the PDF file
