asterisk users - Feb 2005 - Sip question - allow only 1 incoming call to sip phone

Hi,

I need to have it so that if someone is on their sip phone that any
other attempts to contact that phone will result in a transfer to
voicemail.

Someone mentioned there might be a setting like numofcalls = 1 in the
sip.conf so that only 1 call would every be sent to the sip phone but I
would like it to goto voicemail is they are already on the phone.

Thank you in advance to all that can help.

Is it possible to test if a call to SIP/xxx is in place before dialling 
out? This could help a lot to centralize administation of whether or 
not to use call waiting instead of configuring the ATAs.

app_groupcount can be used to provide call counting in any fashion you 
desire.
