asterisk users - Mar 2004 - Call roll-over question...

I have another question for the group.  I'm trying to make the following 
happen on my Cisco phone:

I have two lines configured, 2001 and 3001.  If I'm talking on 2001 and 
someone tries to call me on 2001 I'd like the call to roll over to 3001 and 
then if I don't answer, it goes to Voice mail.  I was able to accomplish
this
using the following sequence in extensions.conf (I'm doing this from memory,
so I hope I got it right).

exten => 2001,1,Dial(SIP/2001,20)
exten => 2001,2,Dial(SIP/3001,20)
exten => 2001,3,Voicemail(u2001)

Now, while this works if I'm talking on 2001, the obvious problem is that if
none of the extensions are busy it will ring 2001 for 4 ring, then head over 
to 3001 for 4 rings until going to voice mail.  So, I then tried the 
following:

exten => 2001,1,ChanIsAvail(SIP/2001)
exten => 2001,2,Dial(SIP/2001,20)
exten => 2001,3,Voicemail(u2001)
exten => 2001,102,Transfer(3001)
exten => 2001,203,Voicemail(2001)
exten => 3001,1,Dial(SIP/3001,20)
exten => 3001,2,Voicemail(u2001)

Which seems (to my newbie eyes) that it should work, but... it doesn't.  If
I
pickup 2001 and call from another extension it goes straight to voice mail.

Both extensions (2001,3001) work on their own, so I'm certain that they are 
configured correctly.  Also, I have "call waiting" shut off on the
cisco
phone (so it should reject the SIP call to 2001 as busy). 

...any ideas?

Thanks!

Try this

exten => 2001,1,Dial(SIP/2001&SIP/3001,20)

This will ring them both at the same time for 20 seconds

Bryan, If you use the `incominglimit=1` option in the device section of the
sip.conf file, then * will consider the device b usy if there is already a call
going on.  This would give you the behavior you are desiring.

try this in extentions.conf, it should do what you want...

exten => 2001,1,ChanIsAvail(SIP/2001&SIP/3001)
exten => 2001,2,SubString,ToDial=${AVAILCHAN}|0|8
exten => 2001,3,Dial(${ToDial},20)
exten => 2001,4,Voicemail(u2001)
exten => 2001,5,Hangup
exten => 2001,104,Voicemail(b2001)
exten => 2001,105,Hangup

exten => 3001,1,ChanIsAvail(SIP/3001&SIP/2001)
exten => 3001,2,SubString,ToDial=${AVAILCHAN}|0|8
exten => 3001,3,Dial(${ToDial},20)
exten => 3001,4,Voicemail(u3001)
exten => 3001,5,Hangup
exten => 3001,104,Voicemail(b3001)
exten => 3001,105,Hangup
