I have seen this with Polycom phones. In my case the problem turned out 
to be because there were several phones behind NAT and the NAT router 
got a little confused. The only solution I could find was to have the 
phones use different ports - ie. 5060, 5061, 5062. When they all shared 
5060 the NAT router was unable to keep track of where an incoming call 
should be routed to.

Hope this helps,
