Looking deep in sip.conf there is

;registertimeout=20   ;retry registration calls every 20 seconds
(default)
;registerattempts=10  ;Number of registration attempts before we give up
                     ; 0 = continue forever, hammering the other server
until it
                                ; accepts the registration
                                ; Default is 0 tries, continue forever

If you have the default i.e. forever this would cause a block at this
point for the external registrations and the internals would also become
blocked on their reregistration.

I had a system try 1547 times to register to it's outside provider (all
night) causing the internals to go to "No service". So when someone came
in in the morning ...
