Hi Les,
Lachlan is correct, be careful because many telcos do not enable caller ID
by default on PRI's and BRI's, call your telco and get them to enable CLI on
the "D" channel, depending where you live it is a chargeable service.
cheers
Andrew

to CH2 on same number.
Hi Les,
The way to fix this is use the command 'isdn caller <num>' on the
router
placing the call. This will prevent it from answering the call coming in. Be
carefull though, if your ISDN service does not have caller ID, it will stop
the router from answering any call regardless the number.
Regards,
Lachlan

Subject: Problem with ISDN when calling between two routers from CH1 to
CH2 on same number.
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
