Dialler Caller screening with ISDN T/A connected to Cisco 2522

[ntwrkrho]

Is it possible to use "dialer caller 123456" command on a dialer interface of a cisco 2522 router with async ISDN TA modems and allow access to the network from that (123456 tel number) location only?

Thank you.

Hi,

If you use "dialer caller" command in dialer profile , this command is used for binding the comming call to the appropriate dialer inrterface. If not macth the number then the authenticated name is used. So you can use it for your purpose.

If you use "dialer caller" command on the rotarry group , it exactly does what you want. It screens the call like "isdn caller" command and doesn't answer the call if the number is not matched. You can use it again.

But in either case you must be able to screen the number.

Hi,

Thank you for your suggestions.

Here is part of the configuration that I tried out. Screening however does not work. Dialer 1 accepts any call. This is the correct way to create a rotary group is it not?

!

interface Serial4

physical-layer async

no ip address

encapsulation ppp

async mode interactive

dialer in-band

dialer rotary-group 1

!

interface Serial5

physical-layer async

no ip address

encapsulation ppp

async mode interactive

dialer in-band

dialer rotary-group 1

!

interface Dialer1

ip address 192.168.1.1 255.255.255.0

encapsulation ppp

dialer in-band

dialer wait-for-carrier-time 60

dialer caller 0212012345

dialer caller 0212012346

dialer map ip 192.168.1.2 name USER-01

dialer map ip 192.168.1.3 name uSER-02

dialer-group 1

Also, Cisco 2522 is running version 11.2 IOS. Will this need be upgraded?

Thank you again
