One way audio when calls are placed on hold

I'm running call manager 3.1 (3a) with 7940's and 7960's. Whenever a call is placed on hold anywhere, it becomes one-way audio after the call is resumed. The calling party can no longer hear the person that was called. This happens on both outside calls in and interoffice. I have checked my router and voice rtp send-recv is configured. There doesn't seem to be any connectivity issues with my phones to my call managers either. I have the call managers configured as Media Termination Points as well. Any thoughts would be greatly appreciated.

Re: One way audio when calls are placed on hold

why do you need an MTP, can you explain your network a liitle bit i.e. what protocol is used to connect to the CCM by your gateways .

Is there a gatekeeper involved for off-net calls. what codec is used btw gateway and ipphones.

confirm that the problem exist when you make an internal call between 2 local Dn's

Re: One way audio when calls are placed on hold

Is the problem with shared lines only or involves unshared lines as well?

What happens if you put the call back on hold and resume it again? Does audio get established two-way?
