Have an AS5350 w/ two E1 PRIs. Can catch a call from a PC w/ ISDN modem fine, it gets answered, user authenticated (locally for now), IP address assigned from the pool, route propagates to other 7 routers, can reach hosts on other routers, etc. "Life is GOOD"
Then, make a second, simultaneous connection, using a different user name from a second PC, "Life is _really_ GOOD". Both callers can reach other hosts on the network, they have IP addresses, etc. (hey, I did not try to see if they could talk to each other, I'll have to try that.)
Drop only the second call, leaving the first still connected and happy. Then call back (from the 2nd PC) with the same username as the first call. Get authenticated, etc., *BUT* the second connection gets the same IP address as the first connection!! "Life is _NOT_ good!!" You can imagine what this does to packets to/from other hosts, and pings fail 50% (typical duplicate address behavior).
The 5350 config is below, user names and passwords and other identifying information have been munged up.....
Your ideas why, when a second call comes in on a different interface, with the same user name that is already in use, that the IP address assigned is the same as the first connection, would be greatly appreciated.
Thanks,
Jason.
