How Vocera Builds a Dialing Sequence

When a user issues a voice command to dial a telephone number or forward a badge call to a telephone or to voice mail, Vocera sends the phone system a sequence of digits to dial. In addition to the phone number itself, the sequence may contain the access codes needed to obtain an outside line (such as a 9), to dial long distance (such as a 9 followed by a 1), or to access company voicemail.

You do not enter these access codes as part of a phone number. You set up these access codes for your entire organization, and Vocera adds them to phone numbers as necessary before dialing. For example, the following figure shows the flow of events that occur when a badge user places a long distance call to a person who is listed in an address book entry.

In this situation, the following events occur:

  1. Dr. Gupta tells the Genie to call Dr. Smith.

    The Vocera server finds Dr. Smith’s telephone number in the address book, then adds long distance access codes to the dial string because Dr. Smith’s area code is different from the local area code.

  2. The Vocera server tells the Telephony server to dial the number.

  3. The Telephony server dials the number.
