<div>Hey everyone,</div>
<div>another one of these 'things' that aren't making any sense to 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.</div>
<div> </div>
<div>Now, after switching to MGCP, all calls fail, since we drop them with "Cause i = 0x80D1 - Invalid call reference value." Q.931 translator shows:</div>

<div>If I understand this correctly, CCM doesn't recognize the incoming SETUP correctly? We're running CCM 3.3.3sr2 and 12.3.4T2 on the gateway.We had to switch back to h.323 and everything works fine again... How do we make CCM understand this scenario? Upgrade CCM/IOS ?
