8.3 Making a Call
Once Linphone is configured appropriately, making a call is straightforward. Depending
on the type of call (see
for reference), the calling procedures differ slightly.
1 Start Linphone using the menu or a command line.
2 Enter the SIP address of the other party at the SIP address prompt. The address
should look like sip:username@domainname or username@hostname
for direct local calls or like username@sipserver or userid@sipserver
for proxied calls or calls using the service of a SIP provider.
3 If using a SIP service provider or a proxy, select the appropriate proxy or provider
from Proxy to use and provide the authentication data requested by this proxy.
4 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
(page 162). 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.
