me: a customer using C2651XM with an ISDN PRI to their legacy
PBX, running Q.sig and the router as a h.323 gateway without problems. Recently
a decision has been made to implement calling name transfers on this line and
thus switch to MGCP. From my point of view, nothing needs to be changed on the
PBX, as they're using Q.sig already.<o:p></o:p></span></font></p>
