Dial-out connection issues - "No free dialer"

Unanswered Question
Dec 13th, 2007

We are attempting a dial-in connection to our equipment at site, with no success. The routers are configured identically (except for IP addresses and phone numbers) to other deployed systems with working dial-in access. We get past PPP Authentication, but then disconnect with a "No free dialer - starting fast idle timer" debug message.

Below is the debug output, and I will follow up with a post of the router config of the router we are dialing out from (phone numbers replaced with ######). Any thoughts or suggestions? Could a faulty modem at the dial-in location cause this? Thanks.
