configuration of ISDN callback on cisco3660 router

[vinay_8812]

Hi, In my data n/w we have cisco3660 main router with 6 PRI lines and dialers are configured for remote ends. The remote end 1721 router with BRI line make call through dialer no. confg. on router. Now for making a callback from central router through PRI to BRI, what are the config chnages are required at both end?

Hi Vinay,

You'll need to configure on the 1721's dialer:

ppp callback request

And on the 3660's dialer:

dialer callback-secure

ppp callback accept
