asterisk users - Nov 2009 - Need opinion about GSM codec for Internet

Dear all, I have implemented an Asterisk SIP server for a WAN VPN over
Internet. We have users distributed along all my country (Argentina) that
register to my Asterisk in order to talk among them.

I'll plan to have voice and voicemail with GSM codec, because we can't
afford the payment for the G.729 licenses (it's an administrative problem of
our company, not an echonomical problem). So in this way Asterisk won't care
about codec traslations, this sounds good.

What do you think about the use of GSM codec for Internet calls ??? Do you
think GSM is the best narrow-band codec if I can't use G.729 ???

Thank you !!!

Alejandro

In my opinion, GSM sounds great but not as good as G.729. So if you can't
afford getting G.729, GSM is the way to go.
