[Asterisk-Users] G729 - how many needed?

[Terence Parker]

I have purchased a single G729 license - however, how many are actually
needed?

All my IP phones have G729a codecs built in (Cisco 7960 / Zultys ZIP2) - I
would have assumed that if the phones can do it, and canreinvite=yes, then
the phones shouldn't need to go through asterisk anyway?

For calls that do go through asterisk, is a single license required for each
side of the stream? (i.e. a connection between two phones needs two
licenses?)

I bought it hoping it could solve some of my bandwidth related problems but
I seem to have no improvement in quality - so I don't know whether it is
because the codec is simply not being used (one is not enough), or whether
it is, but just isn't making a difference.

Typically - does one need two licenses per call? Or is one enough?

(The only thing I seem to successfully use the G729 license for at the
moment is 411 on FWD)
