 |
|
Hello all,
I am running Asterisk 1.4.17. I have 2 Linksys SPA3102's and one
PAP2-NA (I have a second on order). They have G729a built into them.
This is supposed to be compatable with G729. I was trying to have them
use that codec when they talk to each other, but it seems they always
switch to alaw or ulaw (depending on my sip.conf file). Shouldn't they
be able to use G729a in passthru when connecting to each other? My
PAP2 and one SPA3102 are on the LAN, but I have one remote 3102 that
I'd like to use lower bandwidth codec with.
<Snip of sip.conf>
disallow=all
allow=g729
allow=ulaw
allow=alaw
allow=gsm

The PAP2 can only use G.729 on one channel at a time, have you used SIP
debug to find out what's going on?
Have you checked the codec order inside the ATAs themselves?
Don't forget, you can only use G.729 if there is no need to transcode
it. (ie. no recording and no conferencing).

IMHO you cannot use this codec, when asterisk act as proxy and
need translating between codecs (one client negotiate G729 and
second one negotiate somethink other, for example G711a)
