[cisco-voip] Help on Codec negotiation

[Jiten RAJ]

Hi,
I've some problem to understand the negotiation of
codec in H323. In our lab, we have two endpoints who
exchange their capability set this way :

TCS(receive G711, receive G729) --------->
<---------TCS(receive&transmit G729, receive&transmit
G711)

TCSacq------>
<---------TCSacq

OLC(G711)-------->
<---------OLC(G729)

I'm not understanding why they do not open the
channels in both direction using the same codec ?

Thank's for your help.
Jiten
