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.
