We recently deployed an Asterisk System to our company (version 126.96.36.199) and are using Polycom 430 and 650 phones. The issue we are having occurs when users are making outbound calls . If the phone is off the hook (no dial tone) our users need to dial 9-1-Area-Code-Number to make an outside call. If the phone is on hook (dial tone) the user only needs to dial 1-Area Code- Number. If they try to dial 9-1-etc while the phone is on hook they get a message stating that number is not a valid extension. We would like them to always dial 9-1-Area Code- Number,
Below is the dialplan line from our sip.cfg file
Our phones are running BootROM 4.2.1.0275.
Where do I make the change to allow on hook calls to dial 9 to get an outside line?
