I see this with the Polycom's too.  They often become unreachable/reachable
lately (some revision of 1.4.26). But I had not discovered any correlation
to too many SIP qualify messages on the network.
I thought at first these were network issues.
Increasing the SIP qualify timer per extension seems to help.

I presume the bug marshalls will want to see some CLI output with debug
enabled in logger.conf and the *sip set debug* command issued from the CLI
while this is happening.
