We have an issue with the following. Any assistance would be greatly appreciated.
We have SIP trunks that terminate on our Call Manager which is 7.1.3. We take the call from the SIP trunk (Remote DID) and then "translate" that number to a local 4 digit number that is associated with RIGHT FAX. We can hear FAX tone, however RIGHT FAX shows that there are transmission errors. I have setup a SIP profile and selected "Outgoing T.38 INVITE include audio mline". I understand that this should causes the to switch the call from audio to T.38 fax.
