[Asterisk-Users] Jittery meetme conference using Linksys 942 phones

[Rana Dutt]

We have two Linksys 942 phones which sound great when they call each other
directly through Asterisk. But when they both dial in to a meetme conference
room, the sound is very jittery. Other phones like Polycom 501 and Snom 360
sound fine when using meetme.

Both Linksys phones are set to use the default g711u (ulaw) codecs.
Adjusting the jitter buffer and jitter level settings to various values did
not help.

We are running Asterisk 1.2.1 on Centos 4.2 (Linux 2.6x kernel) on a
dual-processor Dell Poweredge 2850 server with 1 Gb RAM. This machine has a
TE-210 Dual-T1 card plugged in. The meetme.conf file has no general
settings, just a list of two conference rooms.

Has anyone else experienced sound quality issues with meetme conferences
using Linksys phones? Any idea what could fix this? Thanks.

Ron
