Problem with leased-line two Cisco 801

[xyCruiseryx]

Moin,

i configured both router for a leased-line connection about 128kb/s (it should be use both B-Chanals (Europe-bundle ISDN)for transmitting)

Problem: sporadically the connection breaks down. I use the line for a digital phone (about ethernet) which should connectto the TK.

(TK-Cisco1^^^^^leased-line^^^^^^Cisco2-Phone)

Is a timeout the problem or is the configuration not correct????

Try debug comands to view live packets. Could be a flapping interface. Do you use dial on demand? If so, are you allowing all the protocols you need to be?
