We have an existing v6 CUCM cluster with a number of C2821 gareways who are running IOS c2800nm-ipvoicek9-mz.151-4.M4.bin.
One of these gwy's has 2 ISDN BRI ports: VIC2-2BRI-NT/TE.
On the V6 CUCM both ports register correctly and work without problems.
We have attempted to migrate this gwy to a v8.6(2) CUCM but then only the first BRI port registers. No way to get the 2nd port working.
Is this a known problem?
rgds, Geert Folens.
