We are deploying CCM 5.1 with ISDN PRI Q931 ports on a 3825 router, using H323 between CCM and Gateway.
Outbound calls all work fine, however, inbound do not work. They are reaching CCM as a simple change the to DN generates a number not assigned error in the 3825. However, I keep getting destination out of order (27) errors. Can anyone point me in the right direction as to where the problem could be.
