16.5 Answering a call Edit source

Ekiga can receive calls in two different ways. First, it can be called directly with sip:user@host, or via SIP provider. Most SIP providers enable you to receive calls from a normal landline to your VoIP account. Depending on the mode in which you use Ekiga, there are several ways in which you are alerted to an incoming call:

Normal application

Incoming calls can only be received and answered if Ekiga is already started. You can hear the ring sound on your headset or your speakers. If Ekiga is not started, the call cannot be received.

Panel applet

Normally, the Ekiga panel applet runs silently without giving any notice of its existence. This changes when a call comes in. The main window of Ekiga opens and you hear a ringing sound on your headset or speakers.

Once you have noticed an incoming call, click Accept to answer the call then start talking. If you do not want to accept this call, click Reject. It is also possible to transfer the call to another SIP address.

16.6 Using the address book Edit source

Ekiga can manage your SIP contacts. All the contacts are displayed in the Contacts list tab, shown in the main window after start-up. To add a contact or a new contact group, select Chat › Add Contact.

If you want to add a new group, enter the group name into the bottom text box and click Add Group. The new group is then added to the group list and preselected.

The following entries are required 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.

Address

Enter a valid SIP address for your contact.

Groups

If you have many contacts, add your own groups.

To call a contact from the address book, double-click the contact. The call is initiated immediately.
