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 deskset 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 140.
