[Asterisk-Users] SIP phones cutting out with Asterisk??

[Dave Henderson]

Hi Alfred,

Thanks for the hint -- I'll be installing Cacti later today to see if
there's something obvious going on.  There's a very high possibilty that
one of the sites I've seen this at is a faulty switch issue (their
server room is running about 40C (100F) when the door's closed
after-hours -- A/C is being installed this weekend, phew!).  The other
site (my office) has a switch that's quite well-behaved, though we do
tend to have less issues with the phones.

Both * servers in question are running 2.4.27...

Thanks for the advice though, I'll let you know how it goes...
