Usage of codecs and protocols

 
When you use Brekeke PBX, depending on the codec types, there are some cases that sound quality may be bad.

Brekeke PBX supports 20ms, 30ms for G.711; 30ms, and 1frame/1packet for iLBC.You may experience poor sound quality when the packet size is not within support level.

When only using Brekeke SIP Server, problem may occur when you use certain codec. Try other machines and different codec types.
