Yes, a good way to do it is to register each line separately, like this:

sip.conf
[100]
type=friend
username=100
secret=100
callerid="100"
host=dynamic
dtmfmode=rfc2833
context=extensions_context
mailbox=100 at vm_context
disallow=all
allow=ulaw

[100b]
type=friend
username=100b
secret=100b
callerid="100"
host=dynamic
dtmfmode=rfc2833
context=extensions_context
disallow=all
allow=ulaw


Then, you can use SetGroup and CheckGroup like this in your dialplan to 
bypass the annoying call waiting "feature":

extensions.conf
exten => 100,1,SetGroup(100)
exten => 100,2,CheckGroup(1)
exten => 100,103,Goto(100b,1)
exten => 100,3,Dial(SIP/100,20)
exten => 100,4,Voicemail(su100)
exten => 100,5,Hangup

exten => 100b,1,Dial(SIP/100b,20)
exten => 100b,2,Voicemail(sb100)
exten => 100b,3,Hangup
exten => 100b,102,Voicemail(sb100)
exten => 100b,103,Hangup
