A note for any Australians using MyNetFone and V3. On approx 10/3/08 MyNetFone made changes that will force the iLBC codec if it is offered for DID numbers. 3CX V3 has no configuration mentioning the iLBC codec. ie u have no option to disable or enable the codec. 3CX v3 advertises to the SIP server that iLBC is supported anyway. Therefore DID inbound audio no longer works as iLBC is selected by the MyNetFone server.
The fix is to remove the ilbc.dll from :\Program Files\3CX PhoneSystem\Bin\Codec, and then restart the server.
