asterisk users - Dec 2007 - Check if SIP user is available or not ?

Hi * users,

Is there any way to check if a SIP user is currently available or not
from the dialplan? By available I mean if a SIP call can be made to
that user.

Thanks

You can use sip show peers.  If an IP address is shown then the user will be
available.

The ChanIsAvail() application provides a rudimentary means of doing this,
but it is not reliable in that it does not cover certain categories of
channel state that might be considered subjectively untenable for call
placement, i.e. a user is on the phone and you do not want to send them
a call by way of call waiting.
