asterisk users - Feb 2008 - Page app, Polycom IP 601, 60 SIP peers, Interesting Issue

Hi All,

I have a pretty standard Asterisk PBX setup with 60 SIP Peers, mostly
Polycom 501's and a receptionist phone, Polycom IP 601 with 3 attached
sidecars and Buddy Watch enabled monitoring all other SIP phones.

The problem occurs when a group (all SIP peers) Page is called.  Not
always but sometimes when the Page is executed, the IP 601 will become
unreachable from Asterisk.  So when the receptionist hangs up the
page, the BYE doesn't get back to Asterisk to release all the Page
channels so they stay open.  I have to restart Asterisk to release all
the open SIP Channels.

What I think is happening is when all the SIP peers are paged,
Asterisk sends 60 hint notifications to the IP 601 and the phone is
overloaded and can't respond to SIP POKE or process the BYE message
back to Asterisk properly.

I'm wondering if I upgrade to a new IP 650 with a faster processor,
will this eliminate the issue?

Has anyone experienced this or have ideas for resolution or further
troubleshooting?

Thanks.

Oh yes!  This has been killing us for about a year.  We've had several
conference calls with my phone vendor and Polycom and it's still not
fixed (or even determined why it is happening).  Polycom keeps saying,
upgrade to the next version of the firmware.  We upgrade, still a problem.
(again, for over a year!)

In my case, the Polycom 601 actually reboots when we page!  When it
comes back up, I have a phantom "meetme" on the Asterisk system and
none of the sidecar lights are correct.  Sometimes, they simply
stop updating completely.

Just FYI,  go to the CLI and type "meetme".  You'll get the
conference
ID and the number of users.  Then, type "meetme kick <confID>
01"
Using, of course, the conference ID.  The "01" is the user that
initiated the meetme.  So, when you kick 01, the rest go away
politely!  This keeps us from having to restart Asterisk.

We are on Bootrom 3.2.3.0002 and SIP 2.2.0.0047 as of yesterday and
we STILL have the problem. Our setup is one Polycom 601 and 25 Polycom
501s that are being paged.

The 601 is powered by PoE with 2 sidecars, so Polycom wants us to put
an actual Power Supply on the phone - thinking the voltage is dropping
and causing the reboot.  I don't buy that, but we are putting one on
next Monday.  We'll see.

Our next plan is to get a 650 and see if it can handle the traffic.
