Hello everybody!
I must configure a CISCO 803 for it to comunicate with a CISCO CL3620 via ISDN.
Both routers have different IPs. The CL3620 is connected to an primary ISDN line, while the 803 is connected to a Basic ISDN line.
If I ping from the 3620 to the 803, I can see the orange light (ISDN) in the front pannel of the 803, and the ISDN channel activates and I receive the replies. But if I ping from the 803 to the 3620, the channel doesn't activate.
I paste the configuration of the 803, in case you can help me out.
Thanks in advance!

Hi
Can you change the ip addressing scheme which you are using currently out there ?
can you assign a /30 ip address on both the ends of your dialer so that you can avoid ip unnumbered command from the dialer.
Also would like know the idea behind having one more static route in addition to the default route..
can you also get the logs once you enable debug isdn q931 with logging or term mon ??

Hi
"Can you change the ip addressing scheme which you are using currently out there ?

I can't change this scheme since it has been used during months in my company. What I can do is try to remove the 'ip unnumbered' command. Just tried it and doesn't work yet.
"Also would like know the idea behind having one more static route in addition to the default route.. "
Yes, maybe it is unnecessary, but I'm a little newbie. One is to allow traffic to the internet, and the other one is to allow traffic to the LAN in the offices.
"can you also get the logs once you enable debug isdn q931 with logging or term mon ??"
OK. I activate the debug, try to ping the 3620 and I get the following for each ping:
-----------------------------------------------------
00:01:17: ISDN BR0 Q931: TX -> SETUP pd = 8 callref = 0x01
Bearer Capability i = 0x8890
Standard = CCITT
Transer Capability = Unrestricted Digital
Transfer Mode = Circuit
Transfer Rate = 64 kbit/s
Channel ID i = 0x83
Called Party Number i = 0x80, '93XXXXXXX'
Plan:Unknown, Type:Unknown
00:01:17: ISDN BR0 Q931: RX <- CALL_PROC pd = 8 callref = 0x81
Channel ID i = 0x8A.
00:01:18: ISDN BR0 Q931: RX <- DISCONNECT pd = 8 callref = 0x81
Cause i = 0x8095 - Call rejected
Display i = 'Call is rejected'
00:01:18: ISDN BR0 Q931: TX -> RELEASE pd = 8 callref = 0x01
Cause i = 0x8095 - Call rejected
00:01:18: ISDN BR0 Q931: RX <- RELEASE_COMP pd = 8 callref = 0x81
Cause i = 0x8095 - Call rejected
-----------------------------------------------------------------
Thanks!

Hi
Can you post the config of the 3620 router too ?
Can you also get the debug details from 3620 router ?
But before doing debug/logging do make sure that your box is not loaded fully,over load may cause router to reboot.
