Helo,
I have a probleme with an interconnexion between two routeurs with isdn BRI interfaces (Cisco 2600 and a Cisco 1700).
The probleme arrive at layer 2 during the isdn connexion initialisation.
It is strange because when i launch the connexion from sig-part-b to sab-801-03 that work, but in the other sens, when i launch the connexion from sab-801-03 to sig-part-b i have an error Cause i =
0x8792 - No user respondingI tryed to use "isdn send-alerting" but without result.
Result of "show ver" :
