Server specs :

XEON E3-1220V2
4 GB RAM
2 x 500GB HD (RAID0)
1 U
HOT-PLUG PSU

Linux sip.server.tld 2.6.32-358.18.1.el6.x86_64 #1 SMP Wed Aug 28 
17:19:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux


There is no transcoding. Calls are using G711a.

Maybe there is some trancoding when using voicemail...

How can I find out if there is trancoding ??




Kind regards,
Jonas.
