If you do call recording on the G729 leg you'll use an additional license. On Thu, May 19, 2016 at 10:32 PM, Fernando Hernandez <fernando@cloudigit.com

Hi All,
Briefly I introduce our system: IPPBX device <-> FreeSwitch <-> bigbluebutton platform
we have two big issues related to FreeSwitch G.729 commercial module.
1. When we receive a call in (from outside IPPBX) to join a meeting we can see in FreeSwitch logs two encoding/decoding outputs, resulting two channels in use for only one call in. At the beginning we thought it was related to an IVR message to ask the user for the meetingID and password, but we "harcoded" that info in FreeSwitch files to directly forward the user into the meeting and we had the same problem. For call out (from BBB to outside phone number) only one channel is used. 2. We have four G.729 channels, For instance, if we run 1 call out (1 G.729 channel in use) and 2 calls in (another 4 channels), the second call in will establish the connection but a weird "KAKAKA" sound will appear. We can see this error message in the log: - [ERR] switch_core_io.c:697 Codec RAW Signed Linear (16 bit) decoder error! [1]
We now it happens because we only have four channels and we are trying to use the fifth one, but if we do the same with calls out, 5 calls out, the fifth one will just be closed as soon as the user pick up the phone and no weird sound will happen.
Thanks and best regards.
