[Asterisk-Dev] G.729 Licenses for Asterisk

[Sudhir Kumar]

We are preparing an Asterisk PBX for a client who is going to use this
with Grandstream phones. All his external calls are routed through
another provider's Cisco AS5300 box. 

Now my question is how many G.729 license's does he need to purchase?
Both Grandstream phones and AS5300 do G.729, hence all the calls are in
pass through mode as far as G.729 is concerned. It is unlikely that more
than 5 people will be checking their voice mails. Should 5 G.729
licenses be sufficient, or need more?

Although it does not matter much in this case as extra $100 for 10 more
licenses is not a big money for this client yet I thought I will seek
clarification as this issue will come up again and again.

Thanks,
