FAQ

SoliCall is designed to improve audio quality in any type of voice call. We offer robust noise reduction algorithms that are capable of attenuating any unwanted sound or voice from phone calls. In addition for cancelling non-human sounds, we can cancel voices of people that are talking nearby. In addition to noise reduction our technology also includes a robust echo cancellation that is used both in the client side and in the network side. Some of our customers embed our technology in their software/devices while others install our plug-and-play products in their network.
Yes. SoliCall offers two products (PBXMate & SoliCall Pro) that can be seamlessly installed in most communication environments. Moreover, you can use these products without making any change to your servers.

PBXMate improves audio quality in your calls and monitor their quality. PBXMate is a centralized solution that is used by conference call providers, contact centers, operators and organization looking to improve audio quality in their network. PBXMate removes the noise generated in your call center and noise generated by participants in your conference bridge. PBXMate removes echo and adjust speech volume. In addition, PBXMate gives you real-time statistics on the quality of your calls.
Yes, PBXMate can be used to monitor the quality of your calls. PBXMate gives you information like: Noise Level, Echo Level, AGC Level, Jitter, Latency/Delay, Packet Loss & MOS Scores. This information is provided both on-line for active calls and off-line for closed calls. 
Yes, PBXMate can cancel both acoustic echo and hybrid echo in your VoIP network. In addition the PBXMate can remove echo generated from both ends of the call.
Yes. Since PBXMate is using the standard SIP protocol,  it can remove echo & eliminate noise from any IP PBX including Asterisk, Nortel, CISCO, FreeSwitch etc.
SoliCall's PBXMate can be integrated in your network in a matter of minutes. The PBXMate suppoprts multiple plug-and-play architectures. For example, when configuring PBXMate as a SIP-Proxy, there is no need to make any change to your server/PBX.
PBXMate is working in production with many brands of PBX. We do not monitor the exact brand/type of each PBX installation since it is of no importance as PBXMate communicate with the PBX using standard protocols. If your PBX complies with SIP standards, there should be no problem.
Usually this means that you are using an old version that is no longer supported. Please download and install the latest version of 

SoliCall Pro

There could many few reasons causing this error message. It can be that the license file you provided does not exists or can not be read. Alternatively the license file you are using is not valid for this version of SoliCall Pro or it had expired. For more information, check the log file C:\Program Files (x86)\SoliCall\log\errLog.
This can happen if you have more than one microphone/pair of speakers. You need to make sure you have configured SoliCall Pro to the mic/speakers you want SoliCall to work with.  Go to Tools --> Options, and under the subsection Sound Devices choose the right device.
Make sure the option of "Echo Cancellation" is enabled. You can increase the aggressiveness of echo cancellation. In addition, 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).
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) The other party should either install SoliCall as well (since SoliCall has built-in algorithms that reduce echo) or use headsets. (3) Activate the option of "Incoming Echo Cancellation" in SoliCall Pro.
Make sure that SoliCall Pro 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.
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 can call the encoder at the end of the call.
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.
Because of software patents and we cannot distribute MP3 encoding software.
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.
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.
This feature enables you to personalize the profile-based noise reduction (PNR). The profile-based noise reduction provides a very powerful ambient noise cancellation. The algorithm focuses on your voice and attenuates sounds that are not originated from your vocal tract. Starting from SoliCall Pro version 1.7.52, a generic profile is provided out-of-the-box and there is no need to record your personal profile.
