Routing with Cisco 2500 and 1000 Series for LAN-ISDN Service- Part 2

Change the Dial Number

Type en to put the router in enable mode:

test.com>en

The password should be the same as the one used to telnet in.

Password:

To view the router's configuration, type:

test.com#show config

There will be a line in the configuration that says:

dialer map IP 38.1.1.1 speed 64 name LD3330 2707000

The 2707000 is the dial number.

NOTE: Record what interface the dialer map IP line is under because you will need to

use that interface when changing the number.

Type config t to configure from terminal.

test.com#config t

Enter configuration commands, one per line.  End with CNTL/Z.

Enter the interface that the dialer map IP line is under:

test.com(config)#interface BRI0

Add in the new dialer map IP line with the new phone number:

test.com(config)#dialer map IP 38.1.1.1 speed 64 name LD3330 [new number]

Now, remove the old dialer map IP line.

To remove a line, type no and then the line.

For example, to remove the old dialer map IP, type:

test.com(config)#no dialer map IP 38.1.1.1 speed 64 name LD3330 2707020

Now leave config mode:

test.com(config)# [control] z

Save changes:

test.com# write mem

[OK]

Verify the new number is in the config:

The new number should be in the dialer map IP line.
