I think you need to upgrade to the latest Asterisk. Your version is pretty

Subject: [Asterisk-Users] meetme conference latency degrades...


> We have recently started making more frequent use of the meetme

> We are using v1.0.8 with a 2.6.11 kernel on our system.

> We generally have 4 callers in it: two with the gsm codec and 2 with g729.
> Initially, the conference works fine and there is little latency.  After

> We have no digium hardware and use ztdummy for our timing device.

> In much smaller systems with Digium hardware, the accuracy is never
