What happens, is when the User joins as dial-in method, since he joins by dialing into the CAA, though it gets resolved internally, SFB Servers treat it as a PSTN call coming it to CAA. SFB Servers does not differentiate whether it is coming from SfB desktop Client/ DeskPhone or Meeting room or gateway, since it is coming in to CAA and it follows the normal Dial-in join process and then SFB serve reject the call 'PSTN Toll Bypass' from next meeting attendee who are from different network site (Unknown Network Site).
