[Asterisk-Users] Sip registration Timers

[Brian J. Schrock]

Hello,

I have my sip stuff seemingly working fine as well as my zaptel stuff 
working great... But I have a problem with sip registration timers (I'm 
guessing here).

In my extensions.conf file I have this...

exten => 2244,1,Dial,Zap/2|25
exten => 2244,2,Dial,Sip/brian|25
exten => 2244,3,VoiceMail,u2244

But if I close my sip phone and a call goes through it will still wait 
the 25 seconds before it goes to voice mail even though my Sip phone is 
not even on. If I restart Asterisk and do not register my sip phone it 
will go straight to voice mail after no one picks up on Zap/2. Is there 
a way to force asterisk to keep checking on this phone say every few 
seconds (5)? Callers are getting confused as to why the long dead air 
and usually hang up and call back in.
