Briefly I introduce our system: IPPBX device <-> FreeSwitch <->
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
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.
