Hello all, We installed the new CISCO ACS 2.6 software on a Windows 2000 server to have remote access through a CISCO 2600 with an E1 PRI. It is running very well. But unfortunately callback is not working. We want to use the callback "Set by caller" option from the Windows User database. When we do a "Debug Radius" on the CISCO 2600, we see that the CISCO tries to callback with a callback-script, but Windows is not sending the number to the CISCO. Here is the config of the access server : hostname 3620 ! aaa new-model aaa authentication login default local aaa authentication ppp default radius aaa authorization exec default none aaa authorization network default radius aaa accounting exec default start-stop radius aaa accounting network default start-stop radius enable secret xxxxx enable password xxxxx ! username xxxxx password xxxxx ip dhcp-server 192.168.80.134 isdn switch-type primary-net5 ! ! controller E1 0/0 framing NO-CRC4 pri-group timeslots 1-31 ! controller E1 0/1 framing NO-CRC4 pri-group timeslots 1-31 ! process-max-time 200 ! interface FastEthernet0/0 ip address 192.168.80.133 255.255.255.0 no cdp enable ! interface Serial0/0:15 no ip address encapsulation ppp dialer rotary-group 1 dialer-group 1 isdn switch-type primary-net5 isdn incoming-voice modem no cdp enable ! interface Serial0/1:15 no ip address isdn switch-type primary-net5 no cdp enable ! interface Group-Async1 ip unnumbered FastEthernet0/0 encapsulation ppp async mode interactive peer default ip address dhcp no cdp enable ppp authentication pap chap group-range 33 62 ppp callback accept ! interface Dialer1 ip unnumbered FastEthernet0/0 encapsulation ppp dialer in-band dialer-group 1 peer default ip address dhcp no cdp enable ppp authentication pap chap ! ip classless ! dialer-list 1 protocol ip permit no cdp run radius-server host 192.168.80.134 auth-port 1812 acct-port 1813 radius-server key xxxxx Has somebody the same experiences ?
