We need more information. 1)who is dialin in with what kind of PC etc 2)how you want to configure callback 1) via router b) via AAA server. 3)Is PC configured properly for callback.

Now looking on the config you have posted, its not clear. You can visit following link for Configuring MS Callback via router Between a Router and a Windows PC

http://www.cisco.com/en/US/tech/tk801/tk36/technologies_configuration_example09186a0080094338.shtml

So if that doesn't work, we need to see the following debug from router for a call and post it here

debug modem

debug ppp negotiation

debug aaa authentication

debug aaa authorization

debug ppp negotiations

debug ppp cbcp

debug callback

Also if you want callback using AAA server, visit

http://cco/en/US/products/sw/secursw/ps2086/products_configuration_example09186a008009404f.shtml

Hi

thanks about your help.I must to say that I want to configure only one of async port (example async 48) to accept callback from local user account on my router and reject all other incoming dial-in from AAA server.I want to use a Windows XP to dialin and my callback number must be asked before performing dialing proccess from router.

I have enabled my pc to accept callback but nothing happend.

thanks

tepatel · ‎04-20-2004

As i have mentioned, we need to see the debugs when you dialin. So post the debugs for a call here.

zahmed · ‎04-20-2004

If you want the router to ask you the callback number, use "ppp callback permit" on the interface.

As Tejal mentioned, we need to see the requested debugs to see why callback is not working.

I've found my problem with debug commands and could solve it.My problem was about Authorization in AAA configuration after config it my callback worked.

Hi Ahmad

I saw your mail on the Cisco’s Discussion Forum site. You had problem with implementing callback at 2610. I have same problem with 3525 and NM-8AM v2. Would you please let me know how you solved the problem. Do you have any suggestion. I have heard about the same problem from some friends. Some of them changed the IOS and solved. Some of them couldn’t solve it. I have tried with IOS 12.3.4 (XD), 12.3.4 (XD1), 12.3.4 (XD3) and 12.3.7 (T2). No response. As you defined, when you remove ppp callback accept command, everything is fine connecting to the 3725.

If you have any suggestion about another topic I will be grateful. I am trying to connect Nokia30 GSM modem to the 3725 Asycn port. (NM-8A/S)

But I couldn’t .

Thanks.

You can use my email hulusi.turgut@servus.com.tr

Hi JMCNIERNEY

Did you get a result on the PPP Callback on your 3725.

I have a similar issue on a 3745 with Group Async interface and PRI. I have had various issues and each IOS has moved the fault along without fixing it.

Now IOS mz.123-10 Callback is offered to Users however will not dial back. Outgoing call is rejected. Have you had any success.

Many thanks

If you are seeing this issue on various IOS images then I will definitely want to try this out in my lab & maybe raise a bug if need be. Can you please post the running configuration (where the callback fails) & the sh ver.

1. Are you configured for callback thru AAA? If yes, can you try locally?

2. If this is MS callback, what is the OS on the PC?

3. If it’s a modem connected to Router as a callback client & 3745 as the callback server then like to know the modem make/ router make?

Thanks, Mak
