VSP715 Administrator and Provisioning Manual
Ringer Settings
The Ringer Settings enable you to provide a distinctive ringing feature via the custom
Alert-Info header associated with an incoming call. This setting overrides the ringer tone
you have set for the account. For example, you can set a unique ringer tone to alert the
VSP715 user upon receiving any incoming calls tagged as "important" in the Alert-Info
header.
The SIP Invite message contains an Alert-Info header that the phone checks in order to
determine which ringer tone to play. The Alert-Info header format is as follows:
Alert-Info: info=info_text
If the header contains the "info" parameter, the phone attempts to match it to the Distinctive
Ringing Text. If there is a match, the associated tone will play. If there is no match, the
default tone for the account will play.
The matching is done on a "first match" basis. In the case of duplicate text strings, the ringer
tone associated with the first matched entry in the Distinctive Ringing Text list will play.
The server-side configuration must be done with your service provider. This is where the
SIP Invite text ("Distinctive Ringing Text") will be derived.
The ringer settings are also available as parameters in the configuration file. See
“"ringersetting" Module: Distinctive Ringer Settings” on page 135 .
