asterisk users - Mar 2009 - tons of open SIP channel between two snom 360

Hi,

I'm monitoring an Asterisk 1.2.18 box because sometimes I get two Snom 
360 phones creating a lot of SIP channels between them and it seems they 
never die.
How can it be?

Thank you.

Giorgio

I would suggest looking for network dropouts and for power dropouts
that will cause conversations to end suddenly without notifying
Asterisk. Also disable the "reboot on ethernet loss" feature of the
snoms, and make sure they are running 6.5.18 or 7.1.39 firmware.
