[Asterisk-Users] Call pickup across technologies (SIP, IAX, MGCP)?

Hm... with the help of the bristuff PickUp() app I was able to solve this 
"unkown extension" for 2 of my 3 cases, but trying to pickup a ringing 
IAX phone with SIP still fails with error "no channel found 2" (bristuff 
"exten => *8,1,PickUp(1)"). All clients have callgroup=1 and 
pickupgroup=1.

If I do "ship show peer <peername>" I get:

  Callgroup    : 1 (2)
  Pickupgroup  : 1 (2)

and I wonder what the (2) is supposed to mean in both cases, the 
errormessage as well as the peer info. Maybe there is a difference in 
implementation of callgroup= in iax.conf where one starts couting at 0 
and the other at 1?

Hm... too bad there is no "iax2 show peer <peername>"...
