[asterisk-users] Paging Application - Polycom 601

Thu Aug 9 10:07:47 CDT 2007

About your "keys sticking"...I had the same issue when I moved my 501s up to
2.x, and after a lot of fiddling around I realized that the problem was my
register timeout (my phones would register every 30 seconds) which
overloaded the phones CPU, resulting in what appeared to be "sticky keys".

I simply changed the register attempts to a longer delay (I actually think I
removed them completely to be honest).  I used reregister for NAT traversal,
but in 2.x there is a NAT keepalive functionality, which has been working
fine for me.

It might be worth trying that out, it would allow you to move to firmware
2.x and get whatever benefits you can get from that.

Regards,

Mike

I'm trying to get more info on how the phones are set up.  This is a
commercial product and I have a web GUI to enable/disable paging.
What that actually does?  I don't know yet.  I'll find out.

The 601 is Calling the page.  (601 is Receptionist)

OK, now I know for sure... Had the 601 crash again this morning and I used
your help in see the meetme info.  This is roughly 20 minutes after the 601
crashed...

I appears it is still in the conference, even after reboot.

I'm finding that out the hard way!

1.6.7.0098

My vendor tried to move to a 2.x firmware, but it had a real bad delay when
reading keys.  It would miss about ever 3rd or 4th key you pressed.
Sometimes, the keys would "stick" and you'd hear the touchtone for 10
seconds or so.  They had me move back to 1.6.7 and it all went away...

Thanks.  Helped alot.

> Still, I don't think that's what's happening here.

I'm no so sure.  The "one way audio" seems to show it's face within an hour
or so after a "page" that crashes the 601.
I "kicked" everyone off the meetme this time within 20 minutes and it's been
2 hours now.  No "one way audio" yet...

Thanks for the help.

Bill
