Hi Noah -

I use the SetGroup function in asterisk to disable call-waiting on
Polycom phones:

[no-callwaiting-out]
exten => _X.,1,SetGroup(${CALLERIDNUM})
exten => _X.,2,Dial(${TRUNK}/${EXTEN:${TRUNKMSD}})
exten => _X.,3,Busy

(Or whatever you have for outgoing calls. Just need to SetGroup here
too, in case your operator is making an outbound call).

[no-callwaiting]
include => default
include => no-callwaiting-out

[default]
exten => 18,1,SetGroup(${EXTEN})
exten => 18,2,CheckGroup(1)
exten => 18,103,Goto(1802,1)
exten => 18,3,Dial(SIP/18,20)
exten => 18,4,Voicemail(u18)
exten => 18,5,Hangup

Then I would do the same for 1802 and 1803 and in sip.conf put 18, 1802
and 1803 in context no-callwaiting.
