I did purchased G729 licenses from www.digium.com, but recently heard g729 passthru is allowed.
Below is my setup. Can you please confirm that i can do regular voice calls & ivr etc, with out licenses:
Cisco 7940 <–>Asterisk<–>Cisco2851(VoiceGateway)<–>PSTN
Cisco 7940 & Cisco2851 have G729 licenses.
When i tried to get it worked, i got following error:
-- Executing [18002662277@users:2] Dial("SIP/3190-b7701ea0", "SIP/10.10.10.253/18002662277") in new stack

Please suggest. (Do i need to install g729 opensource module anywhere? i read about Intel drivers etc…but not sure how to install them on asterisk.
