Hi, All

   I found ilbc lib is included in openwengo 2.2 source. Then I enable this feature at cmake opton file.  I can saw it in configuration gui when I run wengophone. And I can saw it in SIP Invite.
   But I can hear only noise when I make call.

   I notice ILBC is initialized by 20ms mode. While in some payload structure 13.3k appears. I think 13.3k is to 30ms frame, right?

   So this feature still have some works to do?

Best Regards.
