Delay before host calls back
This option is only supported by the callback control protocol. It allows you to specify the amount of time the server waits before calling back. The DIVA LAN ISDN Modem proposes the delay during callback negotiation. The server can either accept or reject it.
Timeout waiting for callback
Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back. During this time, the DIVA LAN ISDN Modem may accept calls that are not from the callback server unless you use call authentication (set the always authenticate remote option as shown on page 87) to validate the incoming call.
To set up callback
Note When you enable callback using the web configuration interface, the DIVA LAN ISDN Modem automatically enables support for incoming data calls (page 83).
