asterisk users - Jan 2009 - Asterisk does not reREGISTER in case of failure

Hi!

I have asterisk 1.4.22 configured to register to a SIP proxy. The 
problem is that if for some reason the registration fails once (e.g. 
REGISTER-401-REGISTER-403), Asterisk does not try to reregister again - 
I have to "sip reload" to trigger a reREGISTER.

I tried the default SIP settings and registerattempts=10 with the same 
result.

Is there something I have to configure? Otherwise I guess it is a bug.

regards
klaus
