Parameter
[ISUBNumberOfDigits]
Web: Play Busy Tone to Tel
[PlayBusyTone2ISDN]
SIP User's Manual
Specifies the number of digits (from the end) that the device
takes from the called number (received from the IP) for the isub
number (in the sent ISDN Setup message). This feature is only
applicable for IP-to-ISDN calls.
The valid value range is 0 to 36. The default value is 0.
This feature operates as follows:
If an isub parameter is received in the Request-URI, for
1
example,
INVITE sip:9565645;isub=1234@host.domain:user=phone
SIP/2.0
then the isub value is sent in the ISDN Setup message as
the destination subaddress.
If the isub parameter is not received in the user part of the
2
Request-URI, the device searches for it in the URI
parameters of the To header, for example,
To: "Alex" <sip: 9565645@host.domain;isub=1234>
If present, the isub value is sent in the ISDN Setup message
as the destination subaddress.
If the isub parameter is not present in the Request-URI
3
header nor To header, the device does the following:
If the called number (that appears in the user part of the
Request-URI) starts with zero (0), for example,
INVITE sip:05694564@host.domain:user=phone
SIP/2.0
then the device maps this called number to the
destination number of the ISDN Setup message, and
the destination subaddress in this ISDN Setup message
remains empty.
If the called number (that appears in the user part of the
Request-URI) does not start with zero, for example,
INVITE sip:5694564@host.domain:user=phone SIP/2.0
then the device maps this called number to the
destination number of the ISDN Setup message, and
the destination subaddress in this ISDN Setup message
then contains y digits from the end of the called number.
The y number of digits can be configured using the
ISUBNumberOfDigits parameter. The default value of
ISUBNumberOfDigits is 0, thus, if this parameter is not
configured, and 1) and 2) scenarios (described above)
have not provided an isub value, the subaddress
remains empty.
Enables the device to play a busy or reorder tone to the PSTN
after a Tel-to-IP call is released.
[0] Don't Play = Immediately sends an ISDN Disconnect
message (default).
[1] Play when Disconnecting = Sends an ISDN Disconnect
message with PI = 8 and plays a busy or reorder tone to the
PSTN (depending on the release cause).
[2] Play before Disconnect = Delays the sending of an ISDN
Disconnect message for a user-defined time (configured by
the TimeForReorderTone parameter) and plays a busy or
reorder tone to the PSTN. This is applicable only if the call is
released from the IP [Busy Here (486) or Not Found (404)]
