If you enabled 'notifycid' one of the limitations is that the calling channel

is only found if it dialed the extension that was subscribed to.  You can now
specify 'ignore-context' for the 'notifycid' option in sip.conf which will, as
it's value implies, ignore the current context of the caller when doing the
lookup.
