 Subject:  voip traffic shaping
 Date:  Tue, 15 Nov 2005 12:04:59 +0500
with more than 15 voip phones working at the same time I get some echo
and buzzing sounds when shaping is turned on. Any ideas as to why echo
happens in voip networks?

I have 1 queue setup for all voip traffic and this has priority 90.
All other trafic is in another queue with priority 10.
Would increasing memory (I have 128MB) help? Any other suggestions?
