- Free Calls VOIP Phone Systems
Major VoIP developers provide a huge variety of different encryption protocols in order to make your calls safer by voip solutions. And there are free and payed programs and protocols. The most simple VoIP business encryption application is Zfone. It is totally free, but it is necessary that both talkers installed that application. All the other calls will not be protected. Another way of protection is to organize a separate, protected LAN, and connect all the VoIP services phones to it, but that’s suitable only for local level. Even closed payed encryption protocols protect your personal information only while the protocol is unknown, but it is a rather short period of time. Due to hack attempts or information leaks those protocols become insecure really fast on voip services..
VoIP wholesale business as any kind of business has its specific failure risks. The main risk is not to get money from your clients. It may happen when a wholesale provider for voip uses postpaid type of payment while selling trafic. There are several ways to minimize this risk. Firstly, work with partners who have a market experience about voip and are well-known among the VoIP services community. Before starting cooperation with a voip partner ensure yourself by means of anti-fraud forums that he hasn't been involved in VoIP fraud activity and check information about the voip provider company. After signing the agreement you should always keep in touch with your partner.
Depending on the size of your company and the infrastructure you already have in place, jumping on the VoIP bandwagon could cost your company next to nothing, or it could entail significant up-front costs. - VoIP requires a broadband connection—and the more simultaneous users you have, the more bandwidth you'll need. If you work alone out of a home office, or if you have only a few employees, you won't have much to worry about; for example, on my setup, running RingCentral's Connection Capacity utility shows that my 15-mbps home Comcast connection could handle 11 calls simultaneously even if I had Netflix, Spotify, and an instant-messaging client running on the network at the same time.
