Both PBX’s are Asterisk based. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>So customer phone [C] connects to hotel PBX [H]. Once [H] disconnects, the survey PBX [S] grabs the call and conducts the survey. [H] must completely disconnect from the call before [S] can start the survey. [H] cannot transfer/forward the call to [S]. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>At a high level the solution seems to be: On [C] connection to [H], [H] sends call information to [S]. [S] issues a SIP JOIN to [C] and joins the call. [S] somehow detects that [H] has disconnected and then begins the survey.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Would the above work conceptually?
