Hello, I've just set up DISA on my * server. I'm using it to avoid cellular overseas calling charges from support staff in the field at our customer sites. Support staff often spend hours on the phone to our UK factory. However, I'm not sure about the implications of reinvite in this arrangement. A support engineer calls in to a DID that I have from VoicePulse Connect. They match the password and dial out to the UK...also via VPC. This I know to work. However, if I allow SIP reinvite then the call, in theory, leaves my server completely for the rest of its duration. Or does it? Is this sensible? Are there issues that I should be concerned about in such an arrangement?
