Hi all,

     I'm having a problem with ISDN when calling between two routers =
from CH1 to CH2 on the same number. (My isdn line has the same number =
for both B channels.)

For example:

 My 1600 at 12.0(14) calls out of B1 and my 2500 11.3(11a) receives on =
B2 no problem.

but if I try to make the call from the 2500 to the 1600 the 2500 calls =
out on B1 AND receives the call on B2. The 1600 does see the call come =
in on B2 but receives a HOST_DISCONNECT_ACK before it can setup the =
call.

What am I doing wrong??

regards,

Les
