One-way audio thru PSTN w/7940 thru PIX

I have a remote user connected PIX-PIX to our CallManager who can call internally with no problems. When they go thru PSTN he gets one-way audio, can be heard by other end but he can't hear the other end. It doesn't matter who initiates the call - same result. Have access-list on both ends whcih should allow it. I have another user who has no problems in this environment.

thanks for the help.

Try this document

I had one-way voice issue before (though not having the same network config as you're), and used "voice rtp-send rec" on both the router and gateay and that had resolved my issue.

HTH.
