Restricting use of an endpoint line to fax-only

摘要

A fax-only setting identifies a value that is used as a counter of a timer. Upon initiating or receiving a call at an endpoint with which the fax-only MIB value is associated, a user device that provides the endpoint begins a timer based on the setting. During the timer period processing circuitry and/or software of the user device associated with the endpoint determines whether a tone generated/received by a call being initiated/received includes a data signal. If the device determines that such a data signal has been generated/received, a call corresponding to the data signal is processed. If the device does not determine that a data signal has been generated/received, the call being initiated or received at the endpoint is dropped.

1. One or more non-transitory computer readable media operable to be executed by a processor operating on a media terminal adapter, the computer readable media upon execution by the processor being operable to cause the media terminal adapter to perform operations, comprising:
configuring an endpoint associated with a line of a user device as fax-only; receiving a call request at the endpoint; setting up a call at the endpoint in response to the call request; starting a timer upon setting up the call at the endpoint, the timer comprising a predetermined period based on a fax-only configuration setting; determining whether a fax or modem tone is detected at the endpoint during the predetermined period; and disconnecting the call if no fax or modem tone is detected during the predetermined period.
