If there is no keyword parameter in the "Alert-Info" header, or the INVITE message contains no
"Alert-Info" header, then the IP phone firmware uses the Bellcore standard ring tone.
Asterisk/BroadWorks Servers
The ring tone keywords that can display in the "Alert-Info" header for an Asterisk and
BroadWorks server are:
• Bellcore-dr2
• Bellcore-dr3
• Bellcore-dr4
• Bellcore-dr5
When the ring tone keywords appear in an "Alert-Info" header from an Asterisk or BroadWorks
server, the IP phone maps the keywords to the default ring tone patterns.
Example:
The following are examples of the Asterisk/BroadWorks Server ring tone keywords:
Alert-Info: <http://127.0.0.1/Bellcore-dr2>
or
Alert-Info: <Bellcore-dr2>
Sylantro Servers
The ring tone keywords that can display in the "Alert-Info" header for a Sylantro server are:
• alert-acd (auto call distribution)
• alert-community-1
• alert-community-2
• alert-community-3
• alert-community-4
• alert-emergency
• alert-external
• alert-group
• alert-internal
• alert-priority
When the ring tone keywords appear in an "Alert-Info" header from a Sylantro server, the
keyword is mapped to the ring tone pattern based on the configuration you set in the Mitel Web
UI or the configuration files.
RING TONE PATTERNS
In IP Telephony, different ringing patterns have different frequencies and cadences. Ring
cadence is the ringing pattern heard by the called party, before they pick up the call.
