Click Call or Answer and wait for the other party to pick up the phone.
5 Once you are done or wish to end the call, click Release or Refuse and leave Linphone.
If you need to tweak the sound parameters during a call, click Show more to show four tabs holding
more options. The first one holds the Sound options for Playback level and Recording level . Use the
sliders to adjust both volumes to fit your needs.
The Presence tab lets you set your online status. This information can be relayed to anyone who tries
to contact you. If you are permanently away and wish to inform the calling party of this fact, just
check
Away . If you are just busy, but want the calling party to retry, check Busy, I'll be back in ... min
and specify how long you will not be reachable. Once you are reachable again, set the status back to
the default (
Reachable ). Whether another party can check your online status is determined by the
Subscribe Policy set in the address book, as described in “Using the Address Book” on page 117 . If
any party listed in your address book published their online status, you can monitor it using the My
online friends tab.
The DTMF tab can be used to enter DTMF codes for checking voice mail. To check your voice mail,
enter the appropriate SIP address and use the keypad in the DTMF tab to enter the voice mail code.
Finally, click Call or Answer as if you were making an ordinary call.
7.4 Answering a Call
Depending on the run mode selected for Linphone, there are several ways you would notice an
incoming call:
Normal Application
Incoming calls can only be received and answered if Linphone is already running. You then
hear the ring sound on your headset or your speakers. If Linphone is not running, the call
cannot be received.
GNOME Panel Applet
Normally, the Linphone panel applet would run silently without giving any notice of its
existence. This changes as soon as a call comes in: the main window of Linphone opens and
you hear a ring sound on your headset or speakers.
Once you have noticed an incoming call, just click Call or Answer to pick up the phone and start
talking. If you do not want to accept this call, click Release of Refuse .
7.5 Using the Address Book
Linphone offers to manage your SIP contacts. Start the address book with Go > Address book . An
empty list window opens. Click Add to add a contact.
The following entries need to be made for a valid contact:
Name
Enter the name of your contact. This may be a full name, but you can also use a nickname here.
Choose something you easily remember this person as. If you choose to see this person's online
status, this name is shown in the
My online friends tab of the main window.
