asterisk users - Jul 2011 - Disabling Polycom "reject" and "DND" or disable Asterisk 486 "Busy Here" actions

Hi,

 

I'm looking to disable rejecting calls from my call center employees. They
are using Polycom phones.  Is there a way to either disable the reject/DND
features on the Polycom phones (don`t think so) or have the Asterisk PBX
ignore  "Got SIP response 486 "Busy Here" back from
12.23.34.45" response
from specific phones/SIP registrations and just keep on ringing?

 

Mike

It is impossible for a SIP UAS to 'ignore' a '486 Busy Here'
response.
SIP phones are not dumb devices like traditional PBX phones, they are 
completely in control of their end of the call. If the phone sends a 
'486 Busy Here' response, it has already dropped the call.

It *is* possible to disable quite a lot of Polycom phone features via 
the configuration file; I would suggest spending some quality time with 
the Administrator's Guide (and ensure you are running 3.x software on 
the phones) to find out if those features can be disabled.

For Firmware 3.3.0 or later.

voIpProt.SIP.serverFeatureControl.localProcessing.dnd="0"
You may also have to add voIpProt.SIP.serverFeatureControl.dnd="1"  
Since Asterisk doesn't support the Polycom "server based DND" that
should effectively disable DND.

If you just want to disable the reject response use
call.rejectBusyOnDnd="0"
