i've a ccm 5.1 at the central site witch is connected to a PRI for normal telephonie.
The branch site is connected over a ISDN-BRI for normal telephonie.
Now the branchsite (cisco 2801) is connected over MPLS with the centralside.
Calls over the MPLS are ok, but my problem is to make calls from the central to the branch when the mpls is disconnected.
How have I configure this ?
Any help is welcome.
