asterisk users - Aug 2006 - Realtime Peers Disappearing

Can someone tell me what this is about? Asterisk seems to be 'losing'
peers. Usually when a peer isn't known (such as when you first start
Asterisk), Asterisk will do a database lookup and find the peer, and then seed
them.

I tried to dial 3254101, and I get the error below. I ran an ngrep and Asterisk
isn't even doing a database query to find the peer. Why would it be doing
this? It's almost as if Asterisk is expiring the phone before the phone
re-registers. The phone is registering with a 900s expirey period. Asterisk has
maxexpirey=3600 and defaultexpiry=900 in sip.conf. When the phone re-registers,
Asterisk repopulates the peer with it's IP address.

Do you have rtcachefriends=yes and rtupdate=yes set in your sip.conf?
