asterisk users - Feb 2005 - Call pickup across technologies (SIP, IAX, MGCP)?

Hi there,

it appears that call pick-up only works _within_ a technolgoy, i.e. with 
a SIP phone when another SIP phone is ringing. Is that correct, or is my 
configuration faulty?


* Case 1:
SIP phone 1 ringing - SIP phone 2 can pick the call up with *8
We are happy! :-)

* Case 2:
IAX phone ringing - SIP phone can't pick the call up:
NOTICE[10250]: Nothing to pick up

* Case 3: 
SIP phone ringing - IAX phone can't pick the call up:
NOTICE[12300]: Rejected connect attempt from 192.168.x.y, reque
st '*8@mycontext' does not exist

The same applies to MGCP and SIP phone interaction.


[features.conf]
pickupexten = *8

[sip.conf and iax.conf]
callgroup=1
pickupgroup=2


Cheers, Philipp

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>"...
