Summary:                    g726 appears broken between 1.4.x and 1.2.x
Description: 
Platform A : 

asterisk 1.2.24
centos/redhat 4.5
intel motherboard
white box assembly

Platform B:
asterisk 1.4.10.1
centos/redhat 4.5
dell poweredge 2650

when trying to use g726 on an IAX2 channel between a 1.4.10 and 1.2.24

platform B is setup to allow both g726 and ulaw, g726 is preferred. 

if, on platform A, I 

disallow=all
allow=g726,ulaw

ulaw always gets chosen w/ a preference of 'unknown'

if I force only g726 

disallow=all
allow=g726 

I get

incoming audio call:
Aug 12 12:39:19 WARNING[18838]: channel.c:509 ast_best_codec: Don't know
any of 0xe800 formats
Aug 12 12:39:19 ERROR[18838]: chan_iax2.c:7478 socket_read: No best format
in 0xe800???

outgoing audio call:
the following shows up on the receiving side (asterisk 1.4.10)
[Aug 12 12:59:02] WARNING[18775]: channel.c:718 ast_best_codec: Don't know
any of 0xe000 formats
[Aug 12 12:59:02] ERROR[18775]: chan_iax2.c:7486 socket_process: No best
format in 0xe000???



could this be a result of 1.2.x referring to g726 as 0xe000 and 1.4.x
referring to g726 as 0xe800? Would that result in the preferred codec
showing up as 'unknown' ?

it doesn't error but it fails to pass audio, i just hear some faint blips
when playing back a sound file. I mentioned this in the first note of this
bug thread. 

if  1.4 side sets g726 and 1.2 side sets g726 i get a negotiation error

if 1.4 side sets g726aal2 and 1.2 side sets g726 i get no error but the
audio stream is illegible

if i set 1.4 side to ulaw and 1.2 side to ulaw the same audio file plays
back fine
