PRI 5E8 Custom IOS support needed for connection to Nortel PBX

We have a Cisco 3745 with IOS 12.3.4T as a Gateway between a CallManager and a Nortel PBX. We know that the Nortel PBX connection is "5E8 custom". We setup the PRI on the 3745 to be 5ESS and it comes up with many errors. Is there an IOS that will support Notrel 5E8 custom on the 3745?

Any help would be appreciated.

Re: PRI 5E8 Custom IOS support needed for connection to Nortel P

You did not specify if this is H.323 or MGCP integration nor the CCM version. 5E8 custom is supported in CCM & IOS. The CCM compatability matrix will help you in your choice for an IOS.

How do you have the endpoints configued in the PBX & the CCM/GW? What kind of errors are you seeing?
