H323 Fast Busy on answer or Call-out

Hi,

We are having a problem with a 2821 and H323. When you call in, the phone rings but the call is dropped on answer, with the internal phone ringing fast busy. On call-out, the other end rings once then goes to fast busy.

I suspect a DSP issue. There are 2 32 channel PVDM2 cards on board, no no issue there. Is there some extra step to enable DSP use on this router? We normally use 2811's which I thought were nearly identical.

Configuration is below, thanks in advance.

Are you using any CTI applications?

No,

Just realised this was posted to the wrong forum, finger trouble.

Sorry
