asterisk users - Apr 2007 - I can't use the 'Group', 'CallGroup' , 'PickupGroup' in SIP channel (asterisk1.4.2)

HI,ALL,

 I have multiple PSTN lines registered as multiple SIP channels (e.g. SIP/line1,
SIP/line2, SIP/line3, etc...), on the multiple gateways( I uses the SIPURA3000).
 I wants to arrange them into an ordered hunting group for outbound calling.
 I used http://www.voip-info.org/wiki/view/hunt-dial+macro for reference. 
 My configure files like blew.
----------------------------------------------------------------------------------------------------------
 sip.conf:
 [300]
 ...
 callgroup=1
 pickupgroup=2

 [400]
 ...
 callgroup=1
 pickupgroup=2
  
------------------------------------------------------------------------------------------------------------
 I take two SIPURA3000 registered on asterisk, useing 300 and 400. The
'Registration State' of SIPURA3000 is Registered.
 
 exten => _X.,1,Dial(SIP/${EXTEN}@300)  , this dialplan works fine.
 
 exten => _X.,1,Dial(SIP/g1/${EXTEN}) , this dialplan can't work.
 and there is always show "no such host g1".
 
 Who can tell me what is wong ,and give me some hints.
 Thank you very much.
