example:

phones A, B and C are configured with callgroup=1 in sip.conf
phone D is configured with pickupgroup=1 in sip.conf

when a call comes in to A, B, C or any combination of them, phone D can pick up 
the call on their behalf.

You're mistaking "group" for "callgroup". Zap example:

group=1
channel=>1-24

this means when you do a Dial(Zap/g1) phones 1 to 24 would all ring. If you 
wanted to emulate the same sort of behavior for your SIP phones, you could do 
something like:

[globals]
SIPGRP1=SIP/100&SIP/101&SIP/102

then in your dialplan you could do a Dial(${SIPGRP1}) to ring all the sip phones.
