[Asterisk-Users] Delays with g729 and SIP. How come?

[Dan Fernandez]

I 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? 

Dan
