asterisk users - Mar 2010 - Minimalize jitter in VoIP calls

Hello list,

what can I do to minimalize the jitter in SIP-calls at server level ?

If at local network level, there is a VoIP-router and their is a
physical network dedicated to IP-phones, but there is still jitter.

When using a Hosted Asterisk server, which settings on the
Asterisk-server can minimalize the jitter between the VoIP-router and
the Asterisk-server on the public internet ??


Kind regards,

Jonas.

Hello list,

I have set the tos-settings in sip.conf as recommended at
http://www.voip-info.org/wiki/view/Asterisk+sip+tos :

sip.conf tos_sip cs3 
sip.conf tos_audio ef

But there is still jitter and audio delay. What other measures can I
take ??

Zoiper softphone --> D-Link router --> ADSL (ISP) --> Asterisk-server
--> ITSP --> rest of the world

The same TOS-settings for sip and audio are set in the Zoiper softphone.
On the workstation there is some minimal web browsing, no hardcore
downloading or file transfer.

Kind regards.
