[Asterisk-Users] fwd on busy when calling multiple extensions at once

[Tor Roberts]

Hi,
I am setting up a dispatch center where will have 4 call takers, all 
with Polycom IP 600 Sip phones. Each phone will be setup with 6 
extensions each. When a new call comes in, the first extension on all 
the phones will ring. This works fine, the problem is when one of the 
dispatchers is already using her first extension and another call comes 
in. What happens now is that the remaining 3 phones ring on the first 
extension, but the dispatcher who is on a call, her phone does not ring. 
I want her second extension ring along with the other 3 phones first 
extensions.

In sip.conf I have all the extensions set to incominglimit=1 and the 
pertinent part of extensions.conf is:

exten => s,1,Dial(SIP/5000&SIP5001&SIP5002&SIP5003,20,tr)
exten => s,2,Dial(SIP/5004&SIP5005&SIP5006&SIP5007,20,tr)

and so on.

If anybody has any insight, or a better solution, that would be great.

Thanks,
