I don't what I am doing wrong, but apparently it is something to do with either Cisco 4500 router running ios 11.3. In router 1: I have DN: 963-5000 SPID1: 25696350000101 DN: 963-5001 SPID2: 25696350010101In router 2: I have DN: 963-6000 SPID1: 25696360000101 DN: 963-6001 SPID2: 25696360010101___________________________________________________hostname r1int bri0ip address 10.0.0.1 255.0.0.0encapsulation pppdialer map ip 10.0.0.2 name r2 broadcast 9636000dialer-group 1dialer-list 1 protocol ip permit___________________________________hostname r2int bri0ip address 10.0.0.2 255.0.0.0encapsulation pppdialer map ip 10.0.0.1 name r1 broadcast 9635000dialer-group 1dialer-list 1 protocol ip permit______________________________________________First Issue: If I ping r2 (10.0.0.2), it will time out, however my interface gets connected. if I do show int bri 0 1 2, it will show bri0:1 is up line protocol is up, but ping will not go through. Because of frustration, I changed the Dial in number in both routers from 9635000 and 9636000 to 2nd Dial in numbers 963-5001 and 963-6001. ping was successfull. I don't know why it will not work on primary DNs. __________________________________________________________________________________________________________Second issue: If I only want r1 to initiate a call, all I have to do remove dialer map command from the r2 router and that should only allow r1 to initiate a call, pretty basic that is what I thought so, but I guess I was wrong. If I do that I can get my interface bri0:1 to up/up mode, but ping will not go through. Some how these 4500 routers want dialer map commands on both routers along with only Second DNs. I spent the whole week in lab troubleshooting this issue, but finally gave up. I even check the logs in ISDN switch and it accepts the calls on it's interface, and that made me think that it is not the switch. However I could be wrong.Can someone please help? I am really frustrated.Thanks in advance,Regards,
