Is there a way to have a toll free number forwarded to a local DID but not have the Toll Free leg still active? Right now if I have a Toll Free number forward to a local DID within the same system I essentially get billed for the Toll Free AND the Local as they both stay active during the call. I think this is call SIP REFER and Twilio mentions of being able to do this on their platform so Im wondering if they can do it is there any reason or limitation as to why FusionPBX cant do this?
