[Asterisk-Users] Callgroup, Pickupgroup and SIP

[Paul Crick]

I think *8# is only in the Zap channel driver. There was talk on the list
recently (past day or two) about moving these hard coded codes (like *70 for
call waiting, *67 to block caller ID etc) out of the Zap channel driver and
in to the dialplan so they could be used on SIP and provide some
commonality.

I don't think you can do call pickup on SIP although the group may prove me
wrong...
