Re: RAS ISDN Multilink not working on Callback

trevora · ‎03-17-2003

I cannot get multilink callback to work to Windows Clients (2000 & XP, have not tried others). The clients can call in with 2 B Channels to a PRI or BRI but callback will not bring up a 2nd channel. I do not see anyplace where the client can be configured to call a 2nd time or to monitor the link threshold.

Below is a show multilink and part of the config.

Hardware is a 3640 running IOS v12.2.12a

Your configuration shows for PRI whereas the debugs show something related to BRI. In your configuration for dialer10, you don't seem to have the 'dialer map' command for dialing back to the clients. Your debug seems to show callback being attempted over BRI. So I am not sure whether the debugs are for the configuration that is shown in the beginning. Add a 'dialer-map' entry and check whether callback succeeds.

Callback works fine with the above config. I just can't get it to callback with a 2nd B Channel.
