<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>I have 4 asterisk
servers. They all have local phones on their local network they manage for
SIP based conversations. We then have IAX between them all for
inter-asterisk connections.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>This setup has
worked well for nearly 2 years now, minor problems here and there but overall
very nice.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>Recently we acquired
some Polycom video conference units. I was able to setup our main server
to host all the video coordination using video over SIP. I was able to
configure the video conference units on the local network, have all 4 of them
(one going to each remote server) displaying 4 videos on the local
network.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>I then sent them out
to their remote facilities and setup Asterisk with as a SIP client on the 3
remote locations to talk to the main server. One at a time we tested them
and they worked one on one.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>Recently we tried to
get two going, and I noticed there seems to be an issue with the SIP
registration if one of the 3 remote SIP clients has already registered.
That is, the other requests are unanswered or not fully registered for some
reason or another. At very random times I've actually managed to get 2 of
the 3 connected, but inevitably I lose one of those 2 shortly
after.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>The
SIP.CONF has been made identical across all 3 remote locations, and the
main server has the same config for each remote site
connecting.</FONT></SPAN></DIV>

<DIV><SPAN class=904124723-29072008><FONT face=Arial size=2>I first want to
confirm that it's possible to have 3 remote Asterisk servers setup as a SIP
client connected to a 4th Asterisk server. </FONT></SPAN></DIV>
