Distinctive Ringing (V2)
The SIP server may provide information indicating a specific type of call within an incoming call.
With firmware V2, the phone can use this information to choose a ring tone according to the
call type.
The relevant information is carried as a string in the SIP Alert-Info header. When this string
matches a specific
Name
, the corresponding ringer is triggered. In the Asterisk dial plan
(
extensions.conf
), this is done by the
SIPAddHeader()
function. The following example
line from an
extensions.conf
, which precedes the line containing the
Dial()
function,
adds the specific string
alert-internal
to the SIP header for a specific number pattern:
exten => _3XXX,1,SIPAddHeader("Alert-Info:alert-internal")
Thus, in this example, the value for
Name
would be "alert-internal".
The
Ringer sound
parameter determines whether a pattern, i. e. melody, or a specific sound
file shall be used as ringer.
Pattern Melody
selects the melody pattern that will be used if
Ringer sound
is set to "Pattern".
Pattern sequence
determines the length for the melody pattern, and the interval between the
repetitions of the pattern. There are 3 variants:
•
"1": 1 sec ON, 4 sec OFF
•
"2": 1 sec ON, 2 sec OFF
•
"3": 0.7 sec ON, 0.7 sec OFF, 0.7 sec ON, 3 sec OFF
The
Duration
parameter determines how long the phone will ring on an incoming call. The
range is 0-300 sec.
With the
Audible
parameter, the ringer can be muted. In this case, an incoming call will be in-
dicated only visually.
