3. Caller ID

3.1. Caller ID Formats

An application can enable the Caller ID feature on specific channels to process Caller ID information as it is received with an incoming call. Caller ID is supported on selected boards only.

Caller ID formats currently supported are:

• Custom Local Area Signaling Services (CLASS) is a standard published by Bellcore:
  • Single Data Message (SDM) format
  • Multiple Data Message (MDM) format
• Analog Calling Line Identity Presentation (ACLIP) is a standard used in Singapore published by the Telecommunications Authority of Singapore:
  • Single Data Message Format (SDMF)
  • Multiple Data Message Format (MDMF)

  NOTE:

  Throughout the discussion of Caller ID, ACLIP SDMF is referred to as SDM, and ACLIP MDMF is referred to as MDM.

• Calling Line Identity Presentation (CLIP) is a standard used in the United Kingdom published by British Telecommunications (BT)
• Japanese Calling Line Identity Presentation (JCLIP) is a standard for "Number Display" used in Japan published by Nippon Telegraph and Telephone Corporation (NTT).

  NOTE:

  JCLIP operation requires that the Japanese country-specific parameter file be installed and configured (select Japan in the Dialogic country configuration).

Caller ID information is received from the CO between the first and second ring for CLASS and ACLIP, and before the first ring for CLIP. CLIP and ACLIP are supported by the D/41ESC boards only.

NOTE:

One or more Caller ID information features may be available from the service provider or Central Office, whom you must contact to determine the available Caller ID options.
