[SIPForum-discussion] G729 variants

[eapugo]

Hello,

This seems like a G.729a  call, annexb set to yes enables that 
functionality of g729b. G.729ab is I believe a variant on cisco UCs or 
other devices that produces better voice compression using VAD and DTX.

I've seen on some devices where it is no specified in the message which 
spec. algorithm it is using but only in the device configuration. happy 
hunting
