My Asterisk has 2 SIP extensiones using Cisco phones. The phones are configured just to use the codec g729. In set this in the phone web-gui and in the sip.conf
The calls works fine from extension-to-extensions.
The Asterisk pbx do not use physicall Asterisk cards, I mean, there is no FXO/FXS,E1,T1 ports, I make calls using a TDM Gateway that has 4 fxo/1 fxs ports.
In this scenario do I need to buy g729 licenses to terminate calls to the SIP TDM Gateway?
