I am trying to integrate the Audiocodes H323 gateway with Callmanager 3.2 sp(C). Audiocodes is a analog gateway. When we dial the extension to IP phone from analog phone, we can't not hear what the perosn speak at IP phone. Ip phone user can listen without any problem. Also I can't make any outbound call through Call manager from the analog phone. My call manager has Mgcp configured. We have router with FXO ports and servicing mgcp application to Call manager.
Cool. I am not sure if AudioCodes has an option to bind on the ethernets, but from what your symptons sound like the Bind statement mentioned before would most likely fix the problem with a Cisco IOS h323 Gtwy. Here is a link to look at a similar situation
Bind the H.323 Signaling to a Specific IP Address on Cisco IOS Gateway/Routers
When the Cisco IOS gateway has multiple active IP interfaces, some of the H.323 signaling may be sourced from one IP address and other parts of it may reference a different source addresses. This can generate various kinds of problems, one of them being one-way audio.
To get around this problem, the H.323 signaling can be bound to a specific source address, which can belong to a physical or virtual interface (loopback). The command syntax to use under the interface configuration mode is h323-gateway voip bind srcaddr . Configure this command under the interface with the IP address that the Cisco CallManager points to.
