A1. What is SoliCall good for?

SoliCall is designed to improve audio quality in VoIP calls or any other type of voice call. Ever get frustrated by the noise of your children when making a business call from home? Have you ever participated in a conference call with some annoying noises or echo in the background? With SoliCall you will sound more professional and allow yourself the flexibility of conversing without worrying too much about background noises and echo. In addition SoliCall offers AGC (Automatic Gain Control) to make sure the volume of the call is always set to a comfortable level. SoliCall is a leading provider of software products focused on improving sound quality in VoIP.


A2. How does the personalized noise reduction work?

SoliCall is designated to reduce noises that do not belong to the primary speaker. The default mode is "Anybody" which means that SoliCall will transmit all human sounds, and so it will narrow its focus on reducing other background noises (e.g., the ticking noise of your keyboard, running water, car horn). By recording a sample of your voice, SoliCall will be able to learn and analyze the acoustic parameters of your voice and to minimize other noises during the call.


A3. Can SoliCall cancel echo in my network?

Yes. Using SoliCall's unique server side/network AEC, you can cancel echo in your network. SoliCall's unique echo cancellation removes echo even with a very long delay. You can use a single instance of SoliCall to remove echo generated on mobile devices with low-end CPU, echo generated by Silverlight/Flash application or echo coming from any remote network.


A4. What is the best product for me?

Although sometimes more than one product can be used, it is important to find the product that will give the best results in your environment. Please go over the following descriptions one by one. Choose the product that best fits your description.

D1. How do I configure SoliCall to work with my VoIP programs?

That's easy. Go to our Integration page and we will guide you through the process.


D2. Add a Speaker - what is it ?

This feature enables you to activate the personalized noise reduction. The personalized noise reduction provides a very powerful ambient noise cancellation. The personalized noise cancellation focuses on your voice and attenuates sounds that are not originated from your vocal tract.


D3. Add a Speaker - how does it work ?

Adding a new speaker is simple. Go to Action --> Add Speaker.
You'll be prompted to a walk-through process that will take few minutes in which your voice sample will be recorded. Once you're done, you can change the default speaker to any person who has a recorded sample of his voice.
The information gathered during the registration process will be stored as part of your speaker profile.

D4. After configuration my microphone or my speakers don't work. What's wrong?

This can happen if you have more than one microphone/pair of speakers. You need to make sure you have configured SoliCall to the mic/speakers you want SoliCall to work with.
Go to Tools --> Options, and under the subsection Sound Devices choose the right device.


D5. The person I'm speaking with hears echo. What can I do?

Try to turn the volume of your microphone down (by using windows control panel ). Also, make sure that the speaker volume is set to allow you to hear the other person conveniently (not too low, but not too high either).


D6. I'm hearing echo. What can I do?

When you hear echo, the problem usually originates at the far end.
We recommend that you ask the other party to:
(1) Set his/her speakers’ volume to a comfortable level (not too high).
Also, they should try to keep their speakers away from the microphone.
(2) Reduce the volume of the microphone.
(3) If the problem remains, the other party should either install SoliCall as well(since SoliCall has built-in algorithms that reduce echo) or use a headset for the specific call.


D7. I cannot hear the other party and vice versa. What could be the problem?

Make sure that SoliCall's application is running.
An easy way to tell is if the icon appears on your task bar. Another issue might be that you are currently adding a speaker. You have to complete or abort the process in order to conduct your call.


D8. When I make a conference call with Yahoo Messenger, SoliCall doesn't seem to work.

When you invite all the participants to start a conference call at once, we found out that in some versions Yahoo makes the call go through Microsoft audio devices and not through SoliCall.
The solution is to invite people separately (i.e. start a regular call and then add more people).


D9. How to record my conversations?

With SoliCall each user can record his conversations regardless of the VoIP program they use. Just right click on the SoliCall icon and choose "Recording Enabled". From that point on, all your conversations will be recorded in one library (you can change the default library at Tools --> Options).
Each session will automatically be saved under the speaker's name. You can stop the recording feature by choosing the "Recording Disabled" option.


D10. Recording files creation. How is it being done?

There are two main recording formats: WAV and MP3 (Stereo and Mono).
You can choose to have more than one format (all it takes is space on your hard disk).
WAV Format - SoliCall creates two files, one with speaker extension (*.spk) and the other with microphone extension (*.mic). When the call ends, SoliCall merges them into a single wave file. It may take a few seconds, depending on the length of the call.
MP3 Format - in order to convert the audio to MP3 format you have to supply an MP3 encoder (e.g. lame.exe). SoliCall will automatically call the encoder at the end of the call.


D11. When I play my recorded calls, I only hear one party. Why?

That's because you listen to it in mono.
Make sure you have two speakers plugged-in and turned-on, and that your settings allow you to hear audio in stereo.
Another option is to change the Recording Format to Mono.


D12. Why don't you distribute an MP3 encoder?

Because of software patents, we cannot distribute MP3 encoding software ourselves.


D13. How to purchase a license?

Open the main screen of the application and go to Help->License for more information.


D14. What is causing the warning message "AEC is temporarily disabled" ?

When this warning message appears it mean that SoliCall cannot perform echo cancellation because different formats are used for the microphone and speakers. Usually this is caused by different applications that simultaneously use the audio device. If you encounter this problem, please close all other applications that might use the audio device for playback and/or recording and make sure only your VoIP application is running.


D15. The voice is fading from time to time. Why?

Usually this happens due to usage of low quality audio device in either side of the call. To resolve this, go to Tools->Options and turn off "Aggressive Noise Reduction".


D16. I got the message "Another instance of SoliCall Pro is already running". Why?

This message appears when multiple users are logged-in together on the same PC. This can happen when the Windows "Switch user" operation was used and it kept both the old user and new user logged-in. This behavior is due to the fact that SoliCall Pro is a special application that is connected to the virtual audio device driver. Therefore only one instance of SoliCall pro can be simultaneously executed on a single computer. To avoid this message simply use the Windows operation "Log Off" before a new user log in.

E20. Why don't you distribute an MP3 encoder?

E1. How do I configure SoliCall to work with my VoIP programs?

That's easy. Go to our Integration page and we will guide you through the process.


E2. Add a new Speaker - how to record a sample of my voice?

Adding a new speaker is simple. Go to Action --> Add Speaker.
You'll be prompted to a walk-through process that will take less then a minute. Once you're done, you can change the default speaker to any person who has a recorded sample of his voice.
The information gathered during the registration process will be stored as part of your speaker profile for later use.

E3. What if there are multiple users on the same computer?

No problem. Each person can register and record his/her voice separately so every user will get his/her own speaker name. That's why we don't require a password - SoliCall is trained to recognize the speaker's voice only, so no one will benefit from falsified use of your SoliCall identity.

E4. What modes does SoliCall have?

The "SoliCall On" mode is the default mode which reduces background noises and cancel echo coming from your end. While in this mode you can turn on the Screen Incoming feature which will improve the quality of the incoming audio by reducing noises coming from the other party as well as suppressing the echo coming from the other party.
You can turn SoliCall off at any time, including during a call, if you want the other party to hear your ambient sound clearly.


E5. What can I learn from the different icons

"---------> SoliCall is on, but is not transferring audio to the other party (either because no conversation is currently being held, or because the speaker was not recognized).
Or ---> SoliCall recognizes your voice (in different levels of certainty).
-----------> SoliCall is off, and no filtering is being made, but SoliCall Audio Device will continue to work.
While in this mode, you can not record calls or add new speakers to SoliCall. Do not exit from SoliCall, or else SoliCall Audio Device will be neutralized (and the VoIP program that was configured to work with SoliCall will not transmit any audio).


E6. Why do I get a message during installation saying that the driver was not Microsoft certified ?

During this period, changes are being made to this driver, hence there is no point in certifying an unfinalised version.


E7. SoliCall stays in Connecting mode and doesn't turn on. why?

We want you to have the most up-to-date version, hence establishing connection will make sure you are notified when the latest version is available for download. If it stays in Connecting mode for more than a minute, make sure you are connected to the Internet and that you can access www.solicall.com with a browser. If you can not access our website, please try again later.
If you can access the website you need to verify that solicall.exe is not blocked by your firewall (via port 80) or by any other program.

If the problem remains, please let our support know and state the time (EST or GMT) and the date when the problem occurred.


E8. After configuration my microphone or my speakers don't work. What's wrong?

This can happen if you have more than one microphone/pair of speakers. You need to make sure you have configured SoliCall to the mic/speakers you want SoliCall to work with.
Go to Tools --> Options, and under the subsection Sound Devices choose the right device.


E9. The person I'm speaking with hears echo. What can I do?

Try to turn the volume of your microphone down (by using the Volume In slider in SoliCall's main window). Also, make sure that the Volume Out slider (which controls your speakers) is set to allow you to hear the other person conveniently (not too low, but not too high either).


E10. I'm hearing echo. What can I do?

When you hear echo, the problem usually originates at the far end.
Try turning the “Screen Incoming” option within SoliCall since this option will suppress echo coming from the far end. If this does not help, we recommend that you ask the other party to:
(1) Set his/her speakers’ volume to a comfortable level (not too high).
Also, they should try to keep their speakers away from the microphone.
(2) Reduce the volume of the microphone.
(3) If the problem remains, the other party should either install SoliCall as well(since SoliCall has built-in algorithms that reduce echo) or use a headset for the specific call.


E11. I cannot hear the other party and vice versa. What could be the problem?

Make sure that SoliCall's application is running.
The mode can be either ON or OFF, but SoliCall has to run (an easy way to tell is if the icon appears on your task bar). Another issue might be that you are currently adding a speaker. You have to complete or abort the process in order to conduct your call.


E12. The other party can hardly hear me, or the beginning of my sentences is cut. why?

Change the speaker to "Anybody" and readjust the Volume In slider.
If this solves the issue there might be a problem with the speaker you are using.
Record new voice samples. However, if the problem remains there might be a problem with the sensitivity of your microphone. If you are using a low-sensitive microphone, talk directly into the mic (don't turn your head away from the mic too often).
If SoliCall's gray icon turns yellow when you talk, it's a good indication that your voice is being transferred. If the problem happens for certain periods during your call, turn SoliCall off for a few seconds and then turn it back on (in a sense, it's like rebooting your computer).


E13. When I make a conference call with Yahoo Messenger, SoliCall doesn't seem to work.

When you invite all the participants to start a conference call at once, we found out that in some versions Yahoo makes the call go through Microsoft audio devices and not through SoliCall.
The solution is to invite people separately (i.e. start a regular call and then add more people).


E14. Why am I not able to turn on "Screen Incoming"?

Sometimes SoftPhones use different format for speaker & microphone channels. When such a behavior is detected, SoliCall will not allow you to turn on "Screen Incoming". You should try again during the call. If this behavior is consists please consult your SoftPhone vendor.


E15. How to record my conversations?

With SoliCall each user can record his conversations regardless of the VoIP program they use. Just right click on the SoliCall icon and choose "Recording Enabled". From that point on, all your conversations will be recorded in one library (you can change the default library at Tools --> Options).
Each session will automatically be saved under the speaker's name. You can stop the recording feature by choosing the "Recording Disabled" option.


E16. Recording files creation. How is it being done?

There are two main recording formats: WAV and MP3 (Stereo and Mono).
You can choose to have more than one format (all it takes is space on your hard disk).
WAV Format - SoliCall creates two files, one with speaker extension (*.spk) and the other with microphone extension (*.mic). When the call ends, SoliCall merges them into a single wave file. It may take a few seconds, depending on the length of the call.
MP3 Format - in order to convert the audio to MP3 format you have to supply an MP3 encoder (e.g. lame.exe). SoliCall will automatically call the encoder at the end of the call.


E17. When I play my recorded calls, I only hear one party. Why?

That's because you listen to it in mono.
Make sure you have two speakers plugged-in and turned-on, and that your settings allow you to hear audio in stereo.
Another option is to change the Recording Format to MP3 Mono.


E18. The recording feature was on, but SoliCall did not create the recorded file. Is it lost?

This is a rare scenario so please make sure you have waited a few minutes


E19. What if I still cannot merge the .MIC & .SPK files ?

Please follow these instructions. Whenever it says "anybody_1"
please replace it with the exact name of the file you have.
1. Remove the anybody_1.tmp file from the recording library (note: do it only if have the .spk & .mic files).
2. Go to Windows "Start" menu, choose "Run" and write "cmd". A command window will open.
3. Use the command "cd" (Change Directory) to go to the directory where the recorded files are stored.
4. In the command window copy paste the following command as is: If you were using high recording quality -
"%SOLICALL_BIN%bwavemp.exe" anybody_1.mic anybody_1.spk anybody_1.wav anybody_1.tmp anybody_1.mp3 anybody_1_mono.mp3 16000 1 1 1 mp3-encoder mp3-stereo-cmd mp3-mono-cmd
If you were using the low recording quality -
"%SOLICALL_BIN%bwavemp.exe" anybody_1.mic anybody_1.spk anybody_1.wav anybody_1.tmp anybody_1.mp3 anybody_1_mono.mp3 8000 1 1 1 mp3-encoder mp3-stereo-cmd mp3-mono-cmd


E20. Why don't you distribute an MP3 encoder?

Because of software patents, we cannot distribute MP3 encoding software ourselves.
