Yes, a 'call' refers to two channels bridged.
Jim, please help me to undertand the numbers. I have two g729 licenses, my
SIP provider uses only g729 and my softphones support g729 too,
asterisk.conf is set in its default value (sln).
When a call (2 channels) is being made and succesfully recorded with
MixMonitor (wav49 format), I see at CLI:
testpbx*CLI> sip show channels
Peer User/ANR Call ID
Format Hold Last Message Expiry Peer
A.B.C.D 987654321 63ffff9237c5976 0x100 (g729) No
Tx: ACK sip-provider1
W.X.Y.Z elder 4e4adc85-b2e21c 0x100 (g729)
No Rx: ACK elder
testpbx*CLI> g729 show licenses
0/2 encoders/decoders of 2 licensed channels are currently in use
Licenses Found:
File: G729-... -- Key: G729-...-- Host-ID: ... -- Channels: 1 (Expires:
20...) (OK)
File: G729-... -- Key: G729-...-- Host-ID: ... -- Channels: 1 (Expires:
20...) (OK)
Thanks for your answers,
Elder
