This is a known problem and it does not matter what zaptel timer you use. A
solution is available in 'svn head' by using
asterisk.conf
internal_timing = yes
OR
Enable internal timing support (-I)
on the command line. I don't know if this has been backported to the stable
branch.

Subject: [Asterisk-Users] meetme conference latency degrades...
We have recently started making more frequent use of the meetme
conference of our * system.
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
about 15min., though, the latency is very noticable and by 25min it's
unbearable.
If we all leave the conference and return, the latency is unnoticable
again.
The load on the box is minimal, and only our meetme is running most of
the time. Checking system load with top shows 0.1 or less.
We have no digium hardware and use ztdummy for our timing device.
zttest yields results generally in the area of 99.96%, but about 3-4%
will be as low as 95%.
In much smaller systems with Digium hardware, the accuracy is never
below 99.98% and is often 100%.
Is this apparent inaccuracy of the ztdummy timer likely the cause of the
increasing latency in our meetme conference?
Is there any way to improve it?
Thank you, in advance, for any help.
