Hello again and thanks for the support. The problem seemed to be that I
needed to enable the g729 codec in the general section...
Thanks.

Ok. Thanks a lot anyway. BTW, do you know how many g729 licenses I
need in this situation? Maybe 1 is not enough. Maybe I need 2: 1
for decoding and one for encoding.

As the documentation states, you need 1 license for each instance of
g729 in use. That license is used to either encode, decode, or both.
The problem that many of us have with the above statement is trying
to figure out exactly what "instance" happens to mean. Past postings
have suggested that an instance may be required when listening to
vm (under some circumstances), while gsm files are played to certain
calls, while a real call is in progress, etc, etc.
You are correct, keeping track of what requires a license can get
complicated. Since they are not expensive, I imagine many people
simply purchase more licenses than are actually necessary.
Phone using g729 listening to voicemail encoded in ULAW, GSM, anything
but g729 => 1 license used
Phone using g729 listening to voicemail encoded in g729 => No licenses
used
I suppose most people only need to be concerned with transcoding
to/from g729 if they are handling a lot of concurrent calls. For
instance, we save all of our client's voicemail in g729 and ULAW
format. By doing that, when our clients use their phones to listen to
messages, we don't have to do any transcoding. Likewise, if they
check their messages from an outside line, by saving the messages in
ULAW format, we don't have to transcode there, either.
As I said, if you are handling a low call volume, then go ahead and
order a few more licenses than you need. If you are going to be
handling a larger call volume, I suggest investing some time to
understand all the ins and outs of transcoding and g729.
