[asterisk-users] Delay on sip channel

[Asterisk User]

Hi,

My SIP service provider terminates calls in meetme in my Asterisk PBX
and am getting delay on those channels. I found following link to
measure delay in meetme and to decrease it eventually.

It says, enable USE_RTC for dahdi_dummy.

I have been using virtual server for hosting Asterisk and I had it
disabled as per one had mentioned here to prevent the crashing which
was happening earlier..(http://www.odindev.com/content/troubles-zaptel-centos-52-xen).

Can you shed some light on the issue?
