1.Question: The setting of the phone too complex to configure for people who doesn’t have VoIP knowledge?
Answer: Yes, we give many settings to make the phone mor flexible to meet the requirement of different customer. We have tried to solve the issue like this way:
a) Every setting has a default value after phone install, people can use the phone in most environment by just configuring the account information.
b) We can customize the setting, e.g., make some settings as non-changed values for our customer. Please contact us if you have such feature request.
2.Question: I already activate the license successfully, why the phone can’t start and show “check
configuration or license” ?
Answer: It is possible you configure wrong IP address for the phone. Please check it in the network information
configuration page. If there are multiple IP addresses in the network, you can specify one IP address for the Phone as stated in chapter 4.2.1.
Check if other application already occupies the port (default 5060) you configured for the
Faram Phone.
If you use the IP auto detect way, please check if there is virtual network card generated by
other software. The way to check it is:
a) Click Start->Run, then input “cmd” to open the Dos window;
b) Input the “ipconfig” command to see how many network cards are available in the
OS.
If you use it in Windows Vista, please make sure if you have access right to the directory.
Because the Faram Phone will write the log file, the phone will fail to start if it can’t do so.
And at this time, no log file will output.
3.Question: I have configured the account information, but still in offline status?
Answer: It is convenient to check whether you are register successfully is to view the SIP
message log. Open the main pop menu as stated in chapter 4.1, click “view message log”,
check whether there is 200 response for your REGISTER message.
If no response back, you need check your network work properly like this way:
a) Click Start run, then input “cmd” to open the Dos window;
b) Input the “ping ” following your domain, to see if response back, if no response back,
check with your network administrator to see physical network is ok.
If SIP response back but it is not 200 response, you need check with the service provider
or your network administrator to confirm if the account is active or not.
4.Question: Why always get call failure while I call others?
Answer: There are possible reasons to get the call failure for a outgoing call:
• Open the main pop menu as stated in chapter 4.1, click “view message log”, check
whether you got the response from the remote side? If not, check network status following
the way in question 2 to see if you can ping the remote side successfully.
• Does he set the DND? If set, then he won’t get call.
• Do you in his black list? If you in his black list, your call will be rejected automatically.
• Check whether the media capability you configured is supported by his phone? if the
media capability is not supported, the call will be rejected automatically without
notification. Your phone and his phone must enable at least one same audio/video
codec so you can talk with him.
5.Question: After making a call, It shows the call is connected, but no video or audio come out?
Answer: If the problem occurred, you need check the below issue:
a) Whether there is a firewall/NAT between you and the remote side. If yes that's
possible, you need check with your service provider or network administrator how to
set the Firewall or NAT to enable the SIP service for you.
b) Open the main pop menu as stated in chapter 4.1, click “view message log”, check
whether the RTP MAP value for the same codec in your INVITE message and
remote 200 response is same or not? If not the same, that’s possible, you can
change the RTP MAP value as stated in chapter 4.2.4 to solve the issue.
c) Other issue? You can try to restart the phone to see if solve the issue. If not solve,
please contact support of Faram Technology with your log file.
6.Question: Call is connected, but the Audio, Video quality is not good.
Answer: The communication between the Faram Phones is going over the IP network, so
the network bandwidth is very important for the video quality. The below tips are used to
address the quality issue:
• Open the Tuning Wizard as stated in chapter 3.5 to adjust the audio, video to the
best quality you can.
• Try to use the AMR-NB, Speex-NB as the audio codec because these codec will
occupy less network bandwidth.
• Discuss with your service provider or network administrator to see if other way to
enhance the network performance.

to open the Windows Task Manager, click the Process Page, try to see if the FaramPhone
existed or not, if it still existed, use “End Process”.
8.Question: While I use the Tuning Wizard to adjust my voice (or video) setting but can’t hear voice (Or
see video), how to do?
Answer: The Tuning Wizard of Faram Phone just provide a simple way for you to tune the
audio & video, if it is not successfully, you need check your computer configuration. If the
audio & video device don’t work:
• Check your sound card is installed properly. You can check the “Sounds and Audio
Devices” in “Control Panel” to see if it is functional.
• For most of the audio, video devices, the manufacture will provide the driver and
utility to test the device, you can use their utility to test the device to make it
functional firstly.
If you can’t solve such problem, ask the support from device manufacturer.
9.Question: What type of SIP server can I choose to setup a network?
Answer: Faram Phone follow the SIP standard, it can interact with SIP server which
following the SIP standard. We have tested with the below SIP server which you may be
chosen: OpenSER SIP Server, Brekeke SIP Server.
If you do not want to setup your SIP server by yourself, you can choose the public SIP Server such as fwd.pulver.com which is tested by us already.
10.Question: Why the video is not clear sometimes at first few seconds after call connected?
(Note: Will be solved in Q1, 2009)
Answer: This is a known issue and it depends on the message delay of your network. As
well, the issue is only appeared at caller side. While we setup a call using SIP, callee side will start media earlier after sending 200 but caller will start media after receiving 200, if the network delay is serious, caller side wonĄŻt get the first video I-frame but get the following P-frame, which will lead to the video not clear. Once the second I-frame is got after few seconds, the video become clear.
If the call is between two FaramPhones, we have added a 500ms delay to send video stream for incoming call, therefore, if message delay in your network is less than 500ms, the issue wonĄŻt be there
