No MOH to PSTN callers and One way speech on "resuming"

We have a problem where I/C or O/G DDI PSTN call to an IP phone is put on hold no MOH is played to the caller. When the call is retrieved off hold using "resume" the PSTN caller cannot hear the IP phone user but the IP phone user can here the PSTN caller.

MOH works internally and N/W MOH is turned on as well.

CM version 3-1-2c ,Gateway 3662 running 12.2.T E1 Primary Rate.

Re: No MOH to PSTN callers and One way speech on "resuming"

Don't know if this helps but we had similar problems with MOH to external PSTN callers. It was partly an IOS issue which we found 12.2(2)T to be most stable, and partly the codec on the voip dial-peer. For some reason IVR and MOH only work when using "codec g711ulaw" on the voip dial-peer. Not sure about the one-way voice as we had no problems in that area.
