H.323 Gateway to Callmanager 4.3 - Signalling works, no audio

Hi,

I'm just trying to get to grips with IPT but I'm having some basic problems.

I've got a 2651XM with FXO and FXS ports. From an analog phone connected to the FXS port I can call numbers on the PSTN, and I can also call from the PSTN to my analog phone via connection plar opx.

I added a callmanager 4.3 server and a bunch of IP phones which can all call each other - so far so good.

However, when I add the gateway to callmanager as a H.323 gateway call signalling is fine (I can change the connection plar opx number to an IP phone and it rings) but I get no audio in either direction.

Any suggestions?

You may want to try using this command if you have multiple IP addresses on your H323 gateway:

interface-level: h323-gateway voip bind srcaddr 1.1.1.1

You can also check this doc I have recently created, little section on using 'show call active voice brief'.

hth,
