I have an HMP application that runs in 1pcc mode.
I am unable to make outbound calls with a single major hosted PBX provider because they always reply "603 Decline".
After much debugging at the hosted provider, they concluded that they are unable to support our SDP because it contains "i=session information", and asked us to remove it.
Is it possible to remove "i=session information" somehow without rewriting the application to use 3pcc mode?
