The first time I came across VOIP six years ago, I dealt with cards. I used to make long-distance calls to Russia and Germany, the connection was unsatisfactory, the voice sounded unrealistic and the background was like constant screeching noise. I got disappointed with that.
A lot has changed since that time. Channels have been widened. I started dealing with Skype and enjoyed it but a number of reasons made me think of an alternative.
Skype has a number of disadvantages: 1. The protocol is closed, no alternative clients; 2. A p2p-based protocol, which means you could have outside traffic: if you pay your operator for every megabyte of the traffic, that outside traffic might turn out to be a quite wasteful; 3. Skype charges more than these of SIP operators for stationary and mobile phone calls; 4. All the Skype’s solutions as regards integration in the existing PBX have been lacking the necessary functions and haven’t been very user-friendly, while it’s not particularly convenient to splurge on a separate mobile phone or computer for Skype’s sake alone.
SIP is a substitute to Skype. SIP means Session Initiation Protocol. It is not a voice transmission protocol but a way to direct the information transmission sessions. Type of transmitted data is specified by a separate SDP (Session Description Protocol). It works together with SIP. You can go to, amongst others, Wikipedia to find out more.
I haven’t pondered over all the hardware options, but they’re aplenty. Software solutions allowing one to use SIP are quite as various as the hardware ones.
All today’s IP-PBX systems are SIP-compatible. Using SIP such huge corporations as Cisco make their own equipment for big corporations and intermediate companies.
I chose my provider rather quickly. So I opted for UcallWeconn, as it provides its users with just the service level one might expect from a company. UcallWeconn gives a common client an opportunity to use the services on the VISA-prepaid basis, while firms are offered to make a contract, sign the SLA and pay the services through a bank.
Another consideration in favor of this specific provider is that its services for home Internet users (i.e. for those who access the Internet via a NAT-like domestic router) are properly organized to our surprise.
