[Asterisk-Users] Camp On configuration?

[Nik Martin]

Is there a clever way to camp on an extension in asterisk?  What I need is a
way to answer my extension (not just a ringing ZAP channel) from any other
phone.  If I'm in another office and hear my phone ringing, I want to be
able to quickly pick it up from that extension.  The list revealed the
pickupgroup parameter, but that looks like it will pick up any zap channel
that's ringing.  This call has already been routed to my SIP phone on my
desk, and I want to specifically pick that call up.  Is that possible?
