[SIPForum-discussion] payload type for G729A and different flavorsof G729

[Jeff Wright]

All implementations I've seen in the past use static PT 18.  Anyone else have any other experiences?

Hi,

I have a confusion in whether to use static payload type i.e. 18 or a
dynamic payload type for G729A while transmitting data over RTP.
The rfc 3551 doesn't specify the PT for G729A. It seems that for G729 or
G729A both the payload types are applicable.
A static payload type of 18 as well as a dynamic payload type can be used.

Please clarify what should be used for the different flavors of G729 codec.

Thanks,
Uday
