    Using a GXW4104 and a BT line, 3CX system (37098.738), a Grandstream DP715 and a 3CX windows phone (12.0.36097)
    Pick up the call on the DP715 - OK - have conversation
    Transfer to the windows phone - connects and have attended conversation whilst music plays on the incoming call
    Hang up the DP715 - windows phone says "put on hold" and all buttons greyed out
    Incoming call - nothing but still connected

    How can the windows phone pickup the call?

    If the call is from a SIP line then it works perfectly

    Try altering 'Support Re-invite' and 'Support Replaces' into Advanced setting for your gateway.
