The questions below are based on common queries we have dealt with from customers who have purchased a Net-PBX system.
Will the Net-PBX require additional wiring?
The Net-PBX works on a standard computer network. If your computers are not networked then additional wiring may be required, but this would be true for most new phone systems. The Net-PBX can be either wired or wireless: the wireless option is often preferred because it is cheaper and more convenient in situations where there is no existing network.
What call quality we can expect using VoIP?
In most cases the quality of the phone calls will be as good as, and often better than, a traditional phone system. When connecting to an external service provider the Internet Telephony Service Provider (ITSP) will offer a Service Level Agreement (SLA), which provides a guarantee for the call quality and call completion.
Does Voice over Internet take all my bandwidth?
Any SIP-based phone system will increase the usage of your network. The routing of traffic and the choice of lower bandwidth codecs will reduce this additional usage. The codec defines how your speech will be compressed for sending over the network, and using a smaller codec typically means fewer problems in the network, resulting in better call quality.
Are there security implications with remote users?
The security risks associated with allowing remote users or connecting to an ITSP are minimal. In both cases, ports need to be opened in your firewall to allow access; however this can be done in a very secure manner and Net-Voice has considerable experience in this area.
Can I use any compliant device from another manufacturer?
Yes. Any SIP-compliant device should work with the Net-PBX. From testing many devices we know that not all device manufacturers adhere to the standards rigorously. Net-Voice offers a device certification program which involves testing all aspects of the SIP device with the Net-PBX. A device is only approved once all the issues have been resolved.
