24.5.2 Call Forward Reminder (Off-Hook) Special Dial Tone
The device plays a special dial tone (stutter dial tone - Tone Type #15) to a specific FXS
endpoint when the phone is off-hooked and when a third-party Application server (AS),
e.g., a softswitch is used to forward calls intended for the endpoint, to another destination.
This is useful in that it reminds the FXS user of this service. This feature does not involve
device subscription (SIP SUBSCRIBE) to the AS.
Activation/deactivation of the service is notified by the server. An unsolicited SIP NOTIFY
request is sent from the AS to the device when the Call Forward service is activated or de-
activated. Depending on this NOTIFY request, the device plays either the standard dial
tone or the special dial tone for Call Forward.
For playing the special dial tone, the received SIP NOTIFY message must contain the
following headers:
From and To:
contain the same information, indicating the specific endpoint
Event:
ua-profile
Content-Type:
"application/sxml"
Message body is the XML body and contains the “dial-tone-pattern” set to "special-
condition-tone" (<ss:dial-tone-pattern>special-condition-tone</ss:dial-tone-pattern>),
which is the special tone indication.
To cancel the special dial tone and playing the regular dial tone, the received SIP NOTIFY
message must contain the following headers:
From and To:
contain the same information, indicating the specific endpoint
Event:
ua-profile
Content-Type:
"application/sxml"
Message body is the XML body containing the “dial-tone-pattern” set to "standard-
condition-tone" (<ss:dial-tone-pattern>standard-condition-tone</ss:dial-tone-pattern>),
which is the regular dial tone indication.
Therefore, the special dial tone is valid until another SIP NOTIFY is received that instructs
otherwise (as described above).
Note:
if the MWI service is active, the MWI dial tone overrides this special Call
Forward dial tone.
24.5.3 Call Forward Reminder Dial Tone (Off-Hook) upon Spanish SIP
Alert-Info
The device plays a special dial tone to FXS phones in off-hook state that are activated with
the call forwarding service. The special dial tone is used as a result of the device receiving
a SIP NOTIFY message from a third-party softswitch providing the call forwarding service
with the following SIP Alert-Info header:
Alert-Info: <http://127.0.0.1/Tono-Espec-Invitacion>;lpi-
aviso=Desvio-Inmediato
This special tone is a stutter dial tone (Tone Type = 15), as defined in the CPT file.
The FXS phone user, connected to the device, activates the call forwarding service by
dialing a special number (e.g., *21*xxxxx) and as a result, the device sends a regular SIP
INVITE message to the softswitch. The softswitch later notifies of the activation of the
forwarding service by sending an unsolicited NOTIFY message with the Alert-Info header,
as mentioned above.
