[Asterisk-Users] Problems with g729

[Dan Fernandez]

I am having some problems with g729 with SIP and ZAP channels.

1)
I have two g729 licences. Very frequetnly (I don´t know what triggers the error)  I get the following warnings and error when I try to place a call via SIP to my X100P. The only way to get out of this is through a restart of *. When the error ocurrs there are no other calls in place. Any ideas?


Error Opening channel:2 not available, see va_g729_init_global(..) WARNING[71694]:File codec_g729b.c line 102 (g729lin_new): No available g729b resource for channel 2
WARNING:[71694] File translate.c Line 111 (ast_translator_build_path):Failed to build translator path from 8 to 6 Zap1-1 answered SIP/105-ce3c
WARNING[71694]: File chan_zap.c Line 3367 (zt_write):Cannot handle frames in 256 format
Hangup Zap/1-1


2)
 have discovered a problem when using g729 under the following setup:

SIP call between a Budgetone 102 and ATA 186  (configured without silence suppresion). Both ends have a ADSL 64kbps. Both ends are behind Linksys routers. The pings between them are aprox. 100ms. No other local users on each end.  * is being hosted on a PIII,128MB. No other calls are being handled at the time of the test.

 Basically, after a few minutes, with g729, both ends consistently start getting delays up to a point where it becomes almost unbearable to speak.  If we switch to g723 the problem goes away.

ANy ideas what´s going on?
