Configuring ISDN caller identification callback with C-DCC
You can configure the router as the client or server of ISDN caller identification callback with C-DCC.
Configuration guidelines
To make a successful callback for an incoming number, make sure that the dial string configured in the dialer route or dialer number command on the dialup interface at the server end is exactly the same as the incoming number.
To leave enough time for a server to call back, set the interval for DCC to make the next call attempt on the client at least 10 seconds longer than that of the server. Hewlett Packard Enterprise recommends that you set interval on the server to 5 seconds (the default) and that on the client to 15 seconds.
Configuring the client of ISDN caller identification callback
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter dialup interface (physical or dialer interface) view. | interface interface-type interface-number | N/A |
3. Configure one or multiple destination addresses and dial strings. | dialer route protocol next-hop-address [ mask network-mask-length ] [ user hostname | broadcast ] * dial-number [ autodial | interface interface-type interface-number ] * | N/A |
4. Set the interval for DCC to make the next call attempt. | dialer timer enable seconds | Optional. Hewlett Packard Enterprise recommends that you use 15 seconds. |
Configuring the server of ISDN caller identification callback
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enter dialup interface (physical or dialer interface) view. | interface interface-type interface-number | N/A |
3. Configure the local end to place ISDN return calls for the specified ISDN calling number. | dialer call-in remote-number [ callback ] | N/A |
4. Configure one or multiple destination addresses and dial strings. | dialer route protocol next-hop-address [ mask network-mask-length ] [ user hostname | broadcast ] * dial-number [ autodial | interface interface-type interface-number ] * | N/A |
5. Configure a dial number for placing calls to a single remote end. | dialer number dial-number | Optional. Use this command instead of the dialer route command if only one remote destination address is involved. |
