5-7: VoIP - Dialing Parameters
Parameter
Description
Dialing Timeout
Dialing timeout specifies the duration (in seconds) of allowed inactivity
between dialed digits. When you work with a proxy or gatekeeper, the
number you have dialed before the dialing process has timed out is sent to
the proxy/gatekeeper as the user ID to be called. This is useful for calling a
remote party without creating a speed dial entry (assuming the remote party
is registered with the proxy/gatekeeper).
Phone Number Size
The maximum length of shortcut numbers that you can enter and the
maximum number of digits that you can dial.
Dial Tone Timeout
The duration of the dial tone, in seconds. If the limit is exceeded, the dial
tone will stop and you will hear a warning tone.
DTMF Transport Mode
DTMFs are the tones generated by your telephone's keypad. Choose either
Inband, RFC 2833, or Via SIP.
Digit Map
Enables the ISP to predefine possible formats (or patterns) for the dialed
number. A match to one of the defined patterns terminates the dialed
number. An ‘x’ in the pattern indicates any digit. ‘;’ separates between
patterns.
Example: '10x;05xxxxxxxx;4xxx'.
In this example, 3 patterns are defined. A number that starts with 10 will be
terminated after the 3rd digit and so on. If the user dials a number that does
not match any pattern, the number will be terminated using the timeout or
when the user presses the pound (‘#’) key.
Dial Plan
This parameter works in conjunction with the Digit Map and enables
translation of specific patterns to specific SIP destination addresses. An ‘x’
represents any dialed digit. Each backslash at the right side of the ‘=’
represents one of the dialed digits.
Example: '4xxx=Line_\\\@10.1.2.3'
This rule will issue a call to 10.1.2.3 with the SIP ID of Line_ followed by the
last 3 digits of the dialed number.
Rules are separated by the character';'
Key Sequence
Choose either 'Flash only' (default) or ‘Flash + digits sequence’.
‘Flash only’ uses only the phone's Flash button. There are 3 scenarios:
(1) During an existing call, if the user presses Flash, the call is put on hold;
a dial tone is heard and the user is able to initiate a second call. Once the
second call is established, on-hooking transfers the first (held) call to the
second call.
(2) During an existing call, if the user presses Flash, the call is put on hold
and a dial tone is heard. The user can initiate a second call and establish a
3-way conference by again pressing Flash after the second call is initiated.
(3) During an existing call, if a call comes in (call waiting), pressing Flash
puts the active call on hold and answers the waiting call; pressing Flash
again toggles between these two calls.
‘Flash + digits sequence’ is where a sequence of Flash + 1 holds a call or
toggles between two existing calls. Flash + 2 makes a call transfer. Flash +
3 establishes a 3-way conference.
