[asterisk-users] Phone losing IP address for a few seconds but doesn't drop call

[Bryan Laird]

Does it loose it's IP address consistently and at a designated  
interval.  I've seen something similar in a number of various cases  
where it was always an issue
of the 'client' device blocking the DHCP renew traffic.  But when it  
went into rebinding it would drop $filter and allow the dhcp traffic  
back through.

I would say check to see if it occurs at a regular interval and  
compare that with the lease times.  Also consider it's sometimes a  
good idea if the phone supports it (I don't know if your does)
but setting up a cheap syslog host that can catch the syslog messages  
from the unit.  Some units will log why they dropped their network  
(ie dhcp) or something.

This was just a wild stab.

Cablemodems are the gateway to the Internet.
