Abstract

Abstract To accommodate calls to a destination number which may be either voice calls or a facsimile call, an answering apparatus receives the call when it is unanswered by a telephone and provides voice mail services. If while handling the call as a voice call a facsimile calling tone is received, the answering apparatus switches to facsimile call handling. If the call is answered by the telephone, the answering apparatus is conferenced in and initiates facsimile call handling if a facsimile calling tone is received. The answering apparatus may be configured to handle other non-voice calls in addition to, or in place of, facsimile calls, such as TTY/TDD calls.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 178 words
A method for handling both voice and non-voice calls on a call path, comprising the steps of: sensing whether or not a telephone associated with said call path has completed a call on said call path; when sensing that said call has not been completed by said associated telephone, (i) completing said call and initiating the playing of a greeting on said call path; (ii) monitoring said call path for a non-voice indicator signal; (iii) on sensing a non-voice indicator signal, initiating handling of said call as a non-voice call and, if said greeting is playing, initiating cessation of said greeting; (iv) on failing to sense said non-voice indictor signal before the end of said greeting, initiating voice mail handling of said call until any said non-voice indicator signal is received; when sensing that said call on said call path has been completed by said associated telephone, (i) monitoring said call path for anon-voice indicator signal; and (ii) on sensing a non-voice indicator signal, initiating the handling of said call on said call path as a non-voice call.
Claim 2
Dependent Claim 49 words
The method of claim 1 including the step of, when sensing that said call on said call path has been completed by said associated telephone, on failing to sense said non-voice indictor signal after a pre-selected time interval, ceasing to monitor said call path for a non-voice indicator signal.
Claim 3
Independent Claim 40 words
The method of any one of claims 1-2 wherein said step of sensing that said call on said call path has not been completed by said associated telephone comprises sensing a preselected number of ringing signals on said call path.
Claim 4
Independent Claim 26 words
The method of any one of claims 1-3 including the step of, on sensing a non-voice indicator signal, disconnecting said associated telephone from said call path.
Claim 5
Independent Claim 53 words
The method of any one of claims 1-4 wherein said non-voice indicator signal is a facsimile transmission signal and wherein said step of handling of said call as a non-voice call comprises one of redirecting said call to a facsimile machine and storing signals on said call path in a facsimile data store.
Claim 6
Independent Claim 52 words
The method of any one of claims 1-4 wherein said non-voice indicator signal comprises TTY transmission signals and wherein said step of handling of said call as a non-voice call comprises one of redirecting said call to a TTY device and storing signals on said call path in a TTY data store.
Claim 7
Independent Claim 32 words
The method of any one of claims 1-6 wherein the step of initiating voice mail handling of said call comprises directing signals on said call path to a voice mail data store.
Claim 8
Independent Claim 185 words
A method for handling both voice and non-voice calls on a call path, comprising the steps of: receiving an indication whether or not a telephone associated with said call path has completed a call on said call path; when receiving an indication that said call has not been completed by said associated telephone, (i) completing said call and initiating the playing of a greeting on said call path; (ii) monitoring said call path for a non-voice indicator signal; (iii) on sensing a non-voice indicator signal, initiating handling of said call as a non-voice call and, if said greeting is playing, initiating cessation of said greeting; (iv) on failing to sense said non-voice indictor signal before the end of said greeting, initiating voice mail handling of said call until any said non-voice indicator signal is received; when receiving an indication that said call on said call path has been completed by said associated telephone, (i) monitoring said call path for a non-voice indicator signal; and (ii) on sensing a non-voice indicator signal, initiating the handling of said call on said call path as a non-voice call.
Claim 9
Dependent Claim 213 words
A voice and non-voice answering apparatus for a call path, comprising: a port for association with said call path and having an on-hook state and an off-hook state; processing means for receiving an indication a call on said call path has not been completed by a telephone associated with said call path within a pre-determined time and thereafter: (i) transitioning said port to said off-hook state; (ii) initiating the playing of a greeting over said port; (iii) monitoring for a non-voice indicator signal received by said port on said call path; (iv) on sensing a non-voice indicator signal, initiating handling of a call on said call path as a non-voice call, and, if said greeting is playing, initiating cessation of said greeting; (v) on failing to sense said non-voice indictor signal before the end of said greeting, initiating voice mail handling of said call until any said non-voice indicator signal is received; and for receiving an indication said call on said call path has been completed by said associated telephone and thereafter: (i) transitioning said port to said off-hook state; (ii) monitoring for a non-voice indicator signal received by said port; and (iii) on sensing a non-voice indicator signal, initiating the handling of said call on said call path as a non-voice call.
Claim 10
Dependent Claim 47 words
The answering apparatus of claim 9 wherein said indication a call on said call path has not be completed by said telephone associated with said call path within a pre-determined time comprises a pre-determined number of ringing signals on said call path sensed by said processing means.
Claim 11
Dependent Claim 38 words
The answering apparatus of any one of claims 9-10 wherein said indication a call on said call path has been completed by said telephone associated with said call path comprises a DC line voltage on said call path.
Claim 12
Dependent Claim 50 words
The answering apparatus of any one of claims 9-11 wherein said processing means has an input line for connection to a local switching system, said processing means for receiving a non-completion signal on said line indicating a call on said call path has not be completed within a pre-determined time.
Claim 13
Dependent Claim 33 words
The answering apparatus of any one of claims 9-12 wherein said processing means is for receiving a completion signal on said input line indicating a call on said call path has been completed.
Claim 14
Dependent Claim 21 words
The answering apparatus of any one of claims 9-13 including a data store associated with said processing means for storing voice-mail.
Claim 15
Dependent Claim 45 words
The answering apparatus of any one of claims 9-14 including a ring generator associated with said processing means, said processing means for initiating handling of said call as a non-voice call by instructing said ring generator to cause a connected facsimile machine to go off-hook.
Claim 16
Dependent Claim 246 words
A telephone switching system comprising: a plurality of line cards; a switch processor for selectively bridging line cards to establish a call path, for sensing on said call path, and for signalling; a port connected to one of said line cards and having an on-hook state and an off-hook state; an answering system processing means for receiving an indication from said switch processor a call on a call path has not been completed by a telephone associated with said call path within a pre-determined time and thereafter: (i) transitioning said port to said off-hook state; (ii) initiating the playing of a greeting over said port; (iii) monitoring for a non-voice indicator signal received by said port on said call path; (iv) on sensing a non-voice indicator signal, initiating handling of a call on said call path as a non-voice call, and, if said greeting is playing, initiating cessation of said greeting; (v) on failing to sense said non-voice indictor signal before the end of said greeting, initiating voice mail handling of said call until any said non-voice indicator signal is received; and for receiving an indication from said switch processor said call on said call path has been completed by said associated telephone and thereafter: (i) transitioning said port to said off-hook state; (ii) monitoring for a non-voice indicator signal received by said port; and (iii) on sensing a non-voice indicator signal, initiating the handling of said call on said call path as a non-voice call.
