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.

Yes, everything is connected to the same switch - which is a very high performance Cisco device. Ping times are the same, well under 1 ms, no dropped packets. Network appears clean. Here is the sip configuration:

[sipura1_line1]
type=friend
username=sipura1_line1
secret=xxx
host=dynamic
context=dialplan-siegel
callerid = 2224
port=5060
qualify=yes
nat=no
canreinvite=no
[xlite]
type=friend
username=siegeld
authname=siegeld
secret=xxx
host=dynamic
context=dialplan-siegel
callerid = 2220
allow=h261
allow=h263
allow=h263p
mailbox=101
