Basic Talafone softphone operations are described in the How To help chapter
Talafone softphone basic settings are described in the Configuring Talafone softphone help chapter
Attention! Some Talafone softphone skins do not have the Options button. In this case, you can use the Options option by right-clicking the Talafone softphone system tray icon or skin.
Main Panel:
You can select the Main panel appearance from available skins. Go to the Skins help page to learn more about this feature.
The standard Main panel has two screens. Some skins may have more.
You may look at the respondent properties. Right-click the respondent and select Properties in the pop-up menu.
If you want to use Speed Dial, or send DTMF signals, you need to activate the dial pad screen by pressing the >> button. Use the * button to enter the dot. Use the C button to enter backspace.
Lost and Out-of-Order Packets:
For quality communication, the number of lost packets should not exceed 10-15%. A large number of out-of order packets means that your network is overloaded or unstable. Congestion in packet switched networks can cause packets to take different routes to reach the same destination. Packets may arrive in the wrong order resulting in garbled speech.
To prevent this, Talafone softphone stores received packets in a special buffer and reorders them. That is why even a large number of out-of-order packets does not always deteriorate the sound quality if the packets arrive within a certain time. If a packet comes too late, it gets lost.
Sound Adjustments:
Go to the Audio Options help page for details.

Compression and Advanced Audio Settings |
|
To change compression and advanced audio settings, click the Advanced Compression Settings button on the Audio tab.
Attention! You must completely understand what you are doing while changing these settings, or you can severely degrade Talafone softphone performance.
Compression Settings
Status: May be either:
Soft: the codec is implemented as a software driver
Hard: the codec is implemented as a hardware device
Disabled: the codec is disabled.
A codec may be enabled or disabled on the Audio Codec Properties panel.
When two VoIP systems are establishing a call, they negotiate an audio compression codec they are going to use. Which codec to choose depends on many factors: what codecs are installed on both systems, bandwidth limitations, desired sound quality, etc. You may adjust Talafone softphone codec preferences on the Advanced Compression Settings panel. During the negotiation, Talafone softphone offers to the remote system the first codec from the list. If the remote system rejects the codec, Talafone softphone offers the next one from top to bottom until they both accept the codec. You may arrange the codecs in the desired order using the Move Up and Move Down buttons. The Use Default button selects the default codec preference. You may also select which codec preferences Talafone softphone will use, local or remote.
If you select a codec and click the Properties button, or double-click the codec, its Audio Codec Properties message will appear: This message shows some of the codec's basic properties. You may also enable or disable the codec on this message.
Talafone softphone Extensions
Lost data recovery allows you to obtain good sound quality over poor Internet connections. The current Talafone softphone version supports Talafone softphone data recovery engine.
Attention! Talafone softphone data recovery engine is not fully H.323-compatible. Use it only while communicating with other Talafone softphone compatible software.
Talafone softphone data recovery engine sends additional IP packets. This doubles bandwidth requirements but completely restores up to 50% of lost packets. This feature is useful for wideband but unstable connections such as Mobile Internet, WaveLan, or Radio Ethernet.
Advanced Audio Settings
These settings allow you to change sizes of various internal Talafone softphone sound buffers and queues. Do not change them unless you completely understand what you are doing, or you may severely degrade the Talafone softphone performance.
If Talafone softphone plays back DTMF signals too loudly, you may disable local DTMF playback by selecting the Disable local DTMF playback option.

Profiles |
|
Talafone softphone may use predefined sets of options for specific types of calls or for calls through different Internet Telephony Service providers (ITSP). Such sets of options are stored in profiles.
An example of a call-type specific profile is that for the direct call to a host using the SIP VoIP protocol. You do not need to enter a complex dial string like sip:johndoe@jd.bigcom.com. Instead, you may select the SIP direct profile and type the URL in the Call to field. Or, if you use several ITSPs, you may easily switch between them just selecting a required profile, usually supplied by the service provider.
You may even write your own profile with your own set of options, such as your Gatekeeper or Gateway parameters, although that requires some knowledge of VoIP technology.
To create a new profile,
- Click the Options button on the Talafone softphone Main panel and go to the Profiles tab
- Click the New button, select profile type, and specify its name.
- Specify the required parameters and click the OK button.
The newly created profile will appear in the profile list.
|
Note: To enter some parameters like a Gatekeeper, Gateway, or SIP proxy address, caller ID, and password, a profile may require initialization.
Note: Some profiles require initializing, that is, they require the user to enter some account-specific information, such as a Gatekeeper, Gateway, or SIP proxy address, phone number, access password, etc. A Service Properties message will appear the first time you select such profile. You may also re-initialize the profile, if its account-specific information changes.
