asterisk users - Jul 2008 - Sipura SPA-3102 and Asterisk

I have a Sipura SPA-3102 that I use to connect an analog phone to Asterisk.  The
analog phone (actually, an analog extension from a Panasonic PBX - but this
should not matter) is connected to the LINE1 port of the Sipura.  I've got
the setup working fine, and when I place a call from the phone on LINE1 to an
X-Lite soft phone, via Asterisk 1.6, all works fine.  Voice quality on the call
is perfect.  Now, I've been playing with MP3Player, using it to stream audio
to an extension.  If I call the streaming audio extension from my X-Lite soft
phone, I hear the mp3 file perfectly.  If I call the same extension from the
phone on my Sipura LINE1, the sound is very choppy.  All these devices are
connected on my local area network, so I don't think there is a networking
problem.

To me, this is odd, because:


-          Voice calls placed from the Sipura LINE1 phone work perfectly

-          MP3 playing  from a call placed on an X-Lite client work perfectly

-          MP3 playing from a call placed on the Sipura LINE1 phone are choppy

I've played with various settings on the Sipura, with no luck in fixing this
issue.

You didn't give details of your networking setup but do you have the 
3102 and then X-Lite client connected to the same switch or router? It 
not, one switch could be dropping packets or slow. Do you qualify both 
devices in Asterisk? Do they have the same ping times?

I haven't done any audio streaming so I can't comment on the behavior of
that application in various circumstances.
