Cisco 2600 Dial up

i have a router 2600 with a integrated modem 16 ports.

when i call the number of telephone related to the modem . there is no request by the modem.

Re: Cisco 2600 Dial up

Your ISDN interface config should look like this:

interface Serial1/0:15

no ip address

no ip directed-broadcast

encapsulation ppp

no logging event link-status

dialer rotary-group 1

isdn switch-type primary-net5

isdn incoming-voice modem

The crucial command is in the last line.

This is a system with a PRI. Dunno what you are using. With BRI interfaces, put this under the corresponding BRI.

Re: Cisco 2600 Dial up

Pl. post the running config here.

Here is the link which has a sample config for 16 analog modems receiving the calls.


Re: Cisco 2600 Dial up

If you just wanted to test if the modem will answer your call, add these commands under "line 1 16"

line 1 16

modem inout

transport input all

stopbits 1

flowcontrol hardware

modem autoconfigure discovery

You should be able to hear a modem tone once your call has been answered.

Then if you want to proceed, just post it...

Hope this helps.
