Example

*Mar 1 00:37:24.235: Di1 DDR: ip (s=10.1.0.1, d=192.168.201.1),

100 bytes, outgoing interesting (ip PERMIT)

*Mar 1 00:37:24.239: Di1 DDR: Cannot place call, no dialer string set.

In this case, no dialer string dial-string is configured on the dialer interface. The router wants to place a call but does not know the number to call. Define a dialer string:

interface Dialer1 dialer string 8134

Inbound Call Issues

This topic describes troubleshooting for unsuccessful incoming calls.

This topic describes troubleshooting for unsuccessful incoming calls.

When incoming calls fail to connect with a dialer profile, there may a problem with binding the physical interface to the dialer interface for that call. Verify that the router meets one of the conditions for binding.

Follow these steps:

Step 1 If the dialer profile is not associated with a dialer pool, debug dialer will indicate the following for an inbound call:

*Mar 1 11:51:24.873: BRI0:1: Authenticated host Branch with no matching dialer profile

Solution: Configure the dialer pool command on the dialer interface.

Step 2 There are four attempts to bind. Assuming that you have more than one dialer profile, the calling line identification (CLID) and dialed number identification service (DNIS) bind attempt fails, and PPP authentication is not configured (preempting the possibility of the fourth test), then the following debug dialer message will be generated on the called router:

┬╗Mar 1 11;59;36.521; ISDN BR0;1; Incoming call rejected, unbindable

Solution: Configure ppp authentication chap | pap [callin] on the physical interface.

Step 3 If PPP authentication is enabled on the physical interface, then the fourth attempt to bind will proceed. The router will use the authenticated username in an attempt to bind to one of the dialer interfaces in the dialer pool. If that attempt fails, you will see the following debug output on the called router.

*Mar 1 12:03:32.227: BRI0:1: Authenticated host Branch with no matching dialer profile

Solution: Configure the dialer remote-name command on the dialer interface. The name specified must exactly match the username provided by the remote router for authentication. In this example, the authenticated username is "Branch."
