ppp callback

I have configured a Cisco 3745 for Remote access

For Dial in all is good however if i Setup Dial back the users do not get connected. I have pinned it down to the ppp Callback Accept command in the Interface Group-Async 1. If the PPP Callback Accept command is inputted the router refuses to verify username and password however if i remove the command the user gets verified and logged in without a problem.

I am running iIOS ""


can any light be shed on this problem.

I have setup dial back without problems in the past and have it running on a sister site with a Cisco 3640.

Re: ppp callback

Instead of dial back accept. Use dial back permit.

This should work.

Re: ppp callback


Sorry for the delayed response. As far as I can see all your config is OK. Maybe it is a bug in IOS.

Sorry I can't help further
