Configuring a Dialer Interface for Dial-In and Callback

Navigate to the Interfaces level in the configuration hierarchy, and select a dialer interface—for example, dl0.

1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Edit.
3. Next to dl0, click Edit.

From the [edit] hierarchy level, enter

edit interfaces dl0

On a logical interface—for example, 0—configure the incoming map options for the dialer interface.

• accept-all—Dialer interface accepts all incoming calls.

  You can configure the accept-all option for only one of the dialer interfaces associated with an ISDN physical interface. The dialer interface with the accept-all option configured is used only if the incoming call's caller ID does not match the caller IDs configured on other dialer interfaces.

• caller—Dialer interface accepts calls from a specific caller ID—for example, 4085550115. You can configure a maximum of 15 caller IDs per dialer interface.

  The same caller ID must not be configured on different dialer interfaces. However, you can configure caller IDs with more or fewer digits on different dialer interfaces. For example, you can configure the caller IDs 14085550115, 4085550115, and 5550115 on different dialer interfaces.

1. In the Unit section, for logical unit number 0, click Dialer options under Encapsulation.
2. Next to Incoming map, click Configure.
3. From the Caller type menu, select Caller.

   Next to Caller, click Add new entry.

4. In the Caller id box, type 4085550115.

1. Enter

   edit unit 0

2. Enter

   edit dialer-options

3. Enter

   set incoming-map caller 4085550115

Configure callback options for the dialer interface

• Callback—Enable this feature to allow the ISDN interface to reject incoming calls, wait for 5 seconds (the default callback wait period), and then call back the incoming number.

  Before configuring callback on a dialer interface, ensure that:

  • The dialer interface is not configured as a backup for a primary interface.
  • The dialer interface does not have a watch list configured.
  • Only one dial string is configured for the dialer interface.
  • Dial-in is configured on the dialer interface of the remote router that is dialing in.
• Callback wait period—Number of seconds to wait before redialing an incoming ISDN call.

1. Select Callback.
2. In the Callback wait period box, type 5.

1. Enter

   set callback

2. Enter

   set callback-wait-period 5
