asterisk users - Feb 2005 - differentiating busy & not connected

folks, 

How can I determine whether a sip device is busy (channel unavailable),
or it is not registered/connected?  

ChanIsAvail only checks the channel availability, so it's not specific
enough.  If I could get the output of "sip show peers" in an AGI
script,
I could create the functionality, but I'm hoping for some dialplan
command sequence.  

Thanks, 

Glen

For the latter try "database show sip" or DBGet(...) respectively.
Won't
work with RealTime in Head though, I assume. ;->

Busy: You can always employ CheckGroup() and the like, although that 
gives you only the Asterisk view of things, not the SIP UAs point of 
view. Maybe sipsak and a custom SIP message can help, but that's of 
course outside of Asterisk.
