Bandwidth used for VoIP is determined by the codec used to convert an analog voice/fax signal to digital data packets. Masiero Voice uses a variety of codecs for voice and fax. Having the proper internet speed is critical for the quality of you VoIP calls.
Note: speed alone does not guarantee optimal results for VoIP. The minimum internet connection speed required for VoIP is between 90 kbps to 156 kbps.
Your phones need a consistent, reserved amount of bandwidth for an excellent call and fax quality. Even just one computer on an internet connection with fast bandwidth speeds can use all of the bandwidth in bursts or frequently, depending on what you are doing on your computer. This creates a bottleneck that causes your phone calls to drop, audio to cut in and out, faxes to fail, and many other call or fax-related issues.
Example: you have 3 phones, 1 fax adapter, and 1 computer = (3 phones) * 90 kpbs + (1 fax adapter) * 100 Kbps, which requires:
- 370 kbps download minimum needed
- 370 kbps upload minimum needed
- use this numbers to then setup Bandwidth Management on your router to stop your 1 from using all the available bandwidth
