[asterisk-users] 10.3 : sip loses registration ?

[sean darcy]

We found this morning we had no SIP connection to another site. sip show 
registry on the main site gave "no authentication". sip show peers on 
the other site showed the peer unspecified.

The odd part about this:  doing sip reload on the main site made it all 
work. Nothing else was changed.

Main site:

  sip show registry
........
SFO:5060                          N      sip_outgoin       105 No 
Authentication    Sat, 14 Apr 2012 14:48:15
4 SIP registrations.
..........

PBX*CLI> sip reload
  Reloading SIP
   == Parsing '/etc/asterisk/sip.conf':   == Found
   == Parsing '/etc/asterisk/users.conf':   == Found
   == Using SIP TOS bits 96
   == Using SIP CoS mark 3
   == Parsing '/etc/asterisk/sip_notify.conf':   == Found
   == Using SIP RTP TOS bits 184
   == Using SIP RTP CoS mark 5

On other site:

sip show peers
.........................
sip_outgoing/s           (Unspecified)                            D   N 
             0        Unmonitored
..........
13 sip peers [Monitored: 3 online, 7 offline Unmonitored: 2 online, 1 
offline]

result of sip reload on main site:
     -- Registered SIP 'sip_outgoing' at xxx.yyy.zzz.aaa:9345


How do I/can I set the main site to retry a registration? I've now 
changed sip.conf to add:

registertimeout=20
registerattempts=0            ;Default is 0 tries, continue forever

But these are the defaults anyhow!

Thanks,
