• Pressing a key twice while editing a number for dialing at that
key, with the receiver in the cradle, returns the phone to idle
state.
• Pressing a key twice while editing a number for dialing at that
key, with the receiver off the hook, erases the number.
Each of these different options will now be explained in detail.
Line
‚Line‘ can be used in one of the following ways:
a. To map a local SIP line: A user can assign the local lines to
programmable keys by selecting this option and setting the
URL of the local line as argument to that key setting. For
example, if a phone has two registrations, [email protected].
com and [email protected], the user has the option to
map two programmable keys to each one of these lines
by selecting ‚Line‘ and setting the respective SIP URL as
argument. In this case, all the calls to a particular line will
go to its matching programmable key, e.g., if 502@my.
proxy.com is mapped at key P2, the LED on that key will
start blinking when there is an incoming call on that line.
Similarly, if the user presses P2 in the idle state with the
receiver on hook, [email protected] will become the
active line for that call. This feature enables the customer
to use his different SIP accounts as he would use different
PSTN phone lines. It is also possible to assign different
ring tones to each SIP line in order to make an acoustic
differentiation. This can be done either on the proxy or on
the phone’s web interface page Confi guration Line 1-12.
b. To map a SIP URL for call pickup: Selecting this option
with a SIP URL as argument will subscribe to dialog state
changes of the phone with that registration. The LED on
that key will show the status of the registration as idle,
talking, or ringing by varying frequencies of blinking. This
allows the user to pick up a ringing call remotely by simply
pressing a key. An example of its usage would be the
mapping of the offi ce reception phone line to the phone
