[SIPForum-discussion] Gateway disconnects while using G729

[Ganeshk R]

Hi,


If User A invites User B having G.729 with annexb=no in offer, What should 
user B (Which supports annex b dtx) reply in 200 OK??
annexb=yes or annexb=no?

Can you please tell me in which rfc, it is mentioned.

Thanks in advance

Regards,

Ganeshkumar R

HI Ganeshk,

Codecs G729 and G729b are not compatible codecs. The called useragent's
seems to be not following the offer-answer model and therefore your
gateway is disconnecting the call.


Kind Regards,
