h1. Help
Blink allows you to communicate in real time over the Internet. To use Blink you need a SIP account from a SIP service provider. Same like using an email program, you must configure Blink with the account you have obtained from your service provider. If things do not work they way you expect, the reasons can be caused mainly by two things, one is Blink software itself and the another one is the communication with the SIP Service Provider. While Blink may not be bug free, most of the problems you encounter when using Blink are related to the network communication with the SIP Service Provider. It is not the end-user who should understand the mechanics about how things work, so the main responsibility of making sure that things work correct falls into the hands of the SIP service provider who must properly setup its SIP infrastructure and support its user base.
h2. Service Provider Problems
If you encounter connectivity problems like inability to receive incoming calls or failure to make outbound calls, you should obtain the SIP trace logs and contact your SIP Service Provider and ask for the reason.
h3. SIP Trace Logs
SIP Protocol trace can be enabled in menu _Blink -> Preferences -> Logging -> SIP trace_. The location of the trace file is:
* Linux: ~/.blink/logs/sip_trace.txt
* Windows XP: C:\Documents and Settings\Username\Application Data\Blink\logs\sip_trace.txt
* Windows Vista and 7: C:\Users\Username\AppData\Roaming\Blink\logs\sip_trace.txt
h2. Software Problems
To report a problem, send an email to support@ag-projects.com. Please paste the relevant logs as explained below.
Please report your OS name and version and Blink version. You can find Blink version in menu _Blink -> About_.
h3. Program Exceptions
On Linux, Blink program exceptions are logged to _/var/log/syslog_.
On Windows, Blink exceptions are logged to _C:\Program Files\Blink\blink.exe-stderr_ and _C:\Program Files\Blink\blink.exe-stdout_
h3. Crash Reports
On Linux, in case of a crash, a core file is generated in the user home directory. If no dump is generated, add to the user profile _ulimit -c unlimited_
On Windows XP, crash dump files can be found in the folowing folder: _C:\Documents and Settings\All Users\Application Data\Microsoft\Dr Watson,_ the filenames are called _drwtsn32.log_ and _user.dmp_. The dump file _user.dmp_ can be analyzed with the Windows Debugger. Load the file _user.dmp_ in "Windows Debugger":http://www.microsoft.com/whdc/devtools/debugging/default.mspx and type _!analyze -v_ to obtain a backtrace. Click "here":http://support.microsoft.com/kb/315263 for instructions on how to use the debugger.
h3. Configuration File
Blink accounts and settings are stored in a flat-text configuration file.
It is critical that you do not edit this file manually. If you did and Blink does not start you must delete the file and start all over again. The location of the configuration file is:
* Linux: _~/.blink/logs/config_
* Windows XP: _C:\Documents and Settings\Username\Application Data\Blink\config_
* Windows Vista and 7: _C:\Users\Username\AppData\Roaming\Blink\config_
If you send the configuration file to us for debugging, use a text editor to strip the passwords and Google token.
h2. SIP Accounts
!>BlinkQTScreenshot-Enrollment.jpg!
|>BlinkQTScreenshot-Enrollment.jpg!
To use Blink you need a SIP Account. At first start, Blink shows the _Add Account_ wizard that helps you configure the initial SIP Account.
If you do not have a SIP Account, Blink can create one for you using the free service provided by SIP2SIP. For more information about this service visit http://sip2sip.info
If you already have a SIP Account, select this option then enter the SIP address in the form of _user@domain_ and _password_. The SIP registrar of the domain is then automatically located in the DNS.
You may configure Blink to use multiple SIP Accounts. To configure a new SIP Account, go to menu _Blink->Accounts->Add Account_.... The Add Account window shows up and you can repeat the steps described above.
After you have configured an account, you can see the status of the registration in the account list of Main Window window. Solid color means that the account has successfully registered, gray color means that the registration has failed or is in progress.
To edit the properties of existing accounts go to menu _Blink -> Accounts -> Manage accounts_.

h2. Alert Panel
Incoming session requests bring up the Alert Panel. Click on the Accept Button to accept a session request. There are two options for rejecting an incoming session request:
Click on the Reject button. The session is rejected with SIP response code 603 and all other SIP devices registered for the same account stop ringing. Forwarding to voicemail or other destinations, when available in the SIP server is also cancelled. You must use this option to terminate all call processing associated with the request.
Click on the Busy button. Blink sends a 486 code back to the caller and stops ringing, other SIP devices keep ringing and forwarding to other destinations remains active as set in the SIP server. You must use this option when you want to pick up the call at a different location or allow the Server to perform other pre-configured routing decisions.
Click on the Escape key. Blink stops ringing and does nothing else with regards to SIP signaling. Use this option when you do not want to take any decission about the call but you do not want to be disturbed by the ring tone either.
The currently selected input and output audio devices are showed for incoming audio session requests.
h2. Audio Calls
Blink has no traditional telephone dialpad, nor you will need one to interact with it. As computers have physical keyboards displaying a classic 12 key dial-pad is a poor design choice for a modern graphical user interface of a rich communications SIP client.
To start an Audio Call, select an existing contact or enter a SIP address or telephone number in the search bar.
Once text is entered in the search bar just press enter to start and audio call to that address.
