Caveats for Cisco IOS Release 12.4
OL-7656-15 Rev. J0
Resolved Caveats—Cisco IOS Release 12.4(7e)
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS interim
Release 12.4(15.6) and that functions as a TGW with all PRI switch types from the user to the
network side. The symptom occurs when the isdn test call interf ace interface-number
dialing-string command is entered at the platform on which the call is initiated, when the originating
gateway (OGW) is configured for the National ISDN (primary-ni) switch type, and when the TGW
is configured for the NT DMS-100 (primary-dms100) switch type. The symptom may also affect
Release 12.4T.
