Hi all, Will G729A codec exhaust the CPU power? If yes, how many concurrent

Btw, if G729A has been purchased and installed, what will happen to the
Asterisk Server crash say hard-disk when down or faulty, any where to do
back up first such as "tar" commands?

Any advice will be appreciated

The amount of cpu consumed in any asterisk system is the sum of all the activities in "your" system, not someone else's. G729 codec cpu consumption only occurs if your system requires translation from another codec to G729 for calls or playing sounds. All g729 calls from a g729 device to another g729 device operate in a pass-through mode, and do not consume codec translation cycles.

There are several good references on the wiki relative to this as well as cpu sizing, etc. Take a look.

The digium g729 codec lives in /usr/lib/asterisk/modules (on a fc3 box) and will be backed up "if" you config your backup appropriately. Not sure what needs to be backed up for the license part of their codec since the license is based on the mac address of your nic card. Someone else will need to comment on that. (Its fairly easy to re-license it with digium anyway.)
