Fax Outgoing Always Use POTS

I have two pots lines in my box and I want to configure my outgoing rule so that if the call is coming from my fax extension (a sip extension using an ATA to interface) I want to make sure it goes out one of the pots lines… because there are some sip trunks (from provider) that faxing doesnt work so well over…

Can anyone help me with this…


Well you could create a custom context to put the exten in and only allow it access to the line you wish

I just set mine up so if i dial 8 to get out it routes to the POTS line, if i dial 9 to get out (with the exception of 911)it goes over my VOIP trunks… real easy that way
