Please,can you tell me the difference between ppp callback permit command and ppp callback accept?

Thank you

Both the command will make the router as "callback server". Callback has to be negotiated in both the cases. But with "permit",

callback client (user) will have a control of cancelling callback from server. While in case of "accept", the callback will be performed by server.

When the client dials in, negotiate callback, and client will be presented with the callback window in which the callback number needs to be specified. With "permit", The client can cancle that window and have a straight ppp connection.

with "accept" cancelling that window will disconnect the connection.

So with "permit" really permit added option to user for callback or straignt ppp connection.

Please,i configured ppp callback permit but it works badly.

User with callback-dialstring "" works correctly and the straight ppp connection is ok, instead user with callback-dialstring 55555555 don't permit the straight ppp connection.Why?

Thanks
