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.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.
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.
