Transcoding showing up more on the log file


Recommended Posts



Since moving from pbxnsip to snom one I have noticed the media CPU usage graph a little higher then normal - even without people playing recordings via the web interface.



Can you look at this and tell me if this is normal?

Call port 134: Different Codecs (local nse/8000, remote g729/8000), callid b06fd3c8@pbx, falling back to transcoding



In the actual call log this call was an incoming call to a DID in the PBX. The call started at 10:13am lasted 6 minutes and ended at 10:19am - it looks like when the call was ending at 10:19am that's when the PBX wanted to do transcoding.


We have each trunk set to G729 first then G711 second.
