I don't have any experience with an Audiocodes Meidant 1000, but I'll try to
help you

We have a lot of these

and if I do a supervised transfer of a PSTN call where I complete the

I don't think you can do that. Here's why: on the Polycom's, the Transfer
button doesn't reappear until the transferree picks up the phone. Unless
something changed in the firmware recently. But, if you're completing it
before the 3rd party answers, it's not an attended transfer.

 the PSTN party hears dead air until the call is answered or goes to
> voicemail.


I would start by making sure the Music on Hold actually works, and that the
SIP phones are properly configured to use a MOH context that actually
exists. If those things check out, I would try using a blind transfer and
see what happens, try transferring when the 3rd party answers (VM or
whatever), and watch the console carefully with as much verbosity as
possible.

 I'm not really sure where to start my troubleshooting.  Any one have any

Hope this helps,
David
