g729 License Necessary?

Been troubleshooting a new freepbx install (newbie). Can hear announcements when i dial 7777 directly from softphone, but hear nothing when dialing from cell or POTS.

Research says possible issue may be codec?

Provider sends g711 and g729 and ulaw. Confused if i still need to get a license for g729 and how that licensing works.


How does POTS use codecs? Is there an IP trunk from/to your provider?

If so, just force to use u/alaw in the trunk setting, we all know these two will definitely work.


And yes, g729 require license.
