[Asterisk-Users] Able to tell if phone is registered?

[Race Vanderdecken]

Look at ast_exists_extension in pbx.c

I have tinkered a bit around them, but not directly coded to it. In the
app_voicemail.c code I think it is used to make sure the extension is
valid. There might be code in there to see if the registration is
active.

Look further I see that chan_sip.c has a sip_show_registry() function
that dumps out the registration state of things.

But the coup de gras maybe the ast_device_state_changed()

When the SIP stack expires a registered phone it calls expire_register()
which calls ast_device_state_changed() to notifiy someone of the state
change.

Kevin,

Thanks for the reply, and thats what I am doing now, but I would really 
like to know in advance if a particular phone has been registered before

taking a certain action.

I was wondering if I could do something with regexten, but seemed like a

messy solution. Is there any other way? I don't mind getting my hands 
dirty with perl or C, but I wouldn't really know where to start ...

Thanks,
Tim
