asterisk users - Mar 2006 - How often do YOU register?

Hi,
How often do you all have your ATAs and phone register with the
asterisk server.  I am doing it once an hour, but now I am wondering
if maybe that is too long in between registrations?

Hi,


Being SER user I use 5 minutes (300 seconds).

But you have to balance between load on your registrar server (like * in 
this case) and keeping your database up to date. Too short 
re-registration in huge system means literally tens of registration per 
second. To long registration means:

a) users will seem available for a prolonged time, even during power 
off, their network failure, etc.

b) if user will change IP address and you have long expiratoin time, he 
will be visible under two or more addresses. Most SIP proxies will 
perform parallel forking - they will contact all IPs. Of coure provided 
that you do not perform any form of registrar database 'purge' or 
cleaning, when registering UA from new IP address
