I bought five g729 licenses and when I call into a conference call it uses 3 of the 5 licenses and when the second caller calls in they use up another 2 licenses not allowing anyone to call in. Why is is that 2 conference callers are using up 5 g729 licenses? Is there away to fix this or do i have to buy more licenses per conference caller? Also how many licenses would have to be bought per caller?
Not sure why it is three instead of two for the first one but I believe each caller is going to take two, one to transcode into the conference bridge and one to transcode from the conference bridge back to each user.
A conference has to be transcoded to a linear format in order to do the mixing, so as a general rule it’s a bad idea to use any compressed codec when going into a conference.
It may not be an option in your case if you really do need these channels to be coming in on g729 but that’s something you may want/need to review. I don’t know your specific circumstance but I’ve seen many users believe they need g729 when often they don’t and it causes them more harm then good.
Yeah from what I am seeing it appears that this can get really costly really quickly as it could end up costing $30.00 per caller. If i wanted to go back to ulaw how could I set that up? Or is there away for the first few callers to use g729 and then the rest use ulaw?
