hi,
we have two (2) different groups of dialin users (DIALIN & TEST)
these two groups have a specific peer default ip address pool (DIALIN or TEST)
these two groups call a different phone number
regarding int BRI 1/6 (dedicating to group TEST), i am not able to allocate ip 192.168.8.250 or 192.168.8.251 which in turn should raise in asyn 81 or 82 ONLY
any hint or links would be truly appreciated
below is the current conf
thx

Your problem is that calls come into BRI lines based upon the number dialed, but when analog calls come into one of these lines, they can be switched to any modem in the router. Part of your confusion seems to be your belief that the lines 81 and 82 are somehow associated with BRI1/6, but line numbers here are referring to modem lines, not BRI interfaces. So, in your config, you have no way of assuring that a call to a specific BRI gets switched to a modem in the group-async interface that you want.
You can rectify this by setting up modem pools and assigning modems to the modem pools. In your case, put lines 65-80 in modem pool PAT, and lines 81 and 82 into modem pool MIKE (of course, you can pick your own names for the modem pools).
Here is a link that should help you with your modem pool config.
Good luck.

hi,
that was great until i found out there is no MODEM-POOL command on our current IOS version :
IOS (tm) 3600 Software (C3640-I-M), Version 12.1(3a)T1, RELEASE SOFTWARE (fc1)
mica-modem-pw.2.7.3.0.bin
i'm calling our cisco reseller to confirm
thx anyway mark

Modem pooling using "modem-pool" is not supported on 3600 related platforms. So There is no way to link isdn interface with the perticualr modem or group of modems.
So in 3600, the incoming modem call will be terminated on the any modem which is free on round robin basis.
Now you can alloate the ip's from different ip address pool for ISDN users only but not the modem users.
Only AS53xx boxes support that modem-pooling.
