I also had some strange one-way audio problems with a 7200 configured as
H323. 12.3(8)7T fixed my issues.

Subject: [cisco-voip] Intermittent audio using Cisco 7200 as a Voice
Gateway
We are having a very strange problem when using a Cisco 7200 as a Voice
Gateway to the PSTN. We have some 7960 phones and CCM version 4.02
(using H.323). Calls internally work fine. Calls externally worked
great for a couple of months and then suddenly we started seeing some
problems. Calls would connect via the PSTN fine, but we would have
one-way audio, or no way audio. An Ethereal capture shows that RTP is
working exactly as it is supposed to be between the 7200 H.323 gateway
and the IP phone even when we have audio problems.
If we reboot the 7200 calls may work anywhere from 5 minutes to an hour,
then they will start to fail, and then anywhere from 20 minutes to 2
hours later, they start working again for a while. Cisco has sent us
brand new DSP cards and we have moved up the IOS chain to 12.3.8T and
still see exactly the same behavior.
The 7200 connects via PRI to a SONUS Gateway which connects via PRI
directly to the PSTN.
It is almost like the 7200 is periodically doing too good a job of echo
cancellation. :-)
Attached is the config. Any suggestions (other than upgrade to a 3845)
would be appreciated.
