If your company is considering the use of VoIP services, depending on the options you choose, you may or may not need to download software. To give you an idea of the companies that offer cutting-edge VoIP software, you might look into the services offered by the following company. Just remember that there are many options for VoIP software but this will provide you with some good information and guidelines for choosing the best software for your business needs.
SJ Labs VoIP Software Company focuses their efforts on developing new applications for the Internet and VoIP calling. The software currently available includes the H 323/SIP softphones that works for Windows, Windows CE, Mac, Gatekeeper, Linux, Codecs, and VoIP protocol implementations. The great aspect of using this VoIP software is the clarity obtained over other VoIP software solutions.
The difference with this VoIP software solution is that many of the other software options are based on individual users. With SJ Labs, a new infrastructure has been created that allows your business to run on a single box that is attached to IP phones. The other option is to scale to a network of hosts that literally processes hundreds of calls between thousands of business callers.
This new VoIP software is called the Vovida Open Communications Applications Library or VOCAL for short, and is a completely functional phone system, which can be run on Sun Solaris or Red Hat Linux. If you want to download this VoIP software, you can visit www.vovida.org
The VOCAL VoIP software is based on a communication standard known as Session Initiation Protocol, or SIP. This standard describes a series of network components and signaling methods that includes a User Agent (UA). This agent is the main interface and can be used with a unique piece of hardware just like what is used with an SIP IP phone. This adapter is able to translate the difference between an analog phone signal and the SIP, or VoIP software, which runs on a computer.
Okay, so how does this VoIP software work? The UA, when on the hook, is considered inactive and idle. When a business call is made, the caller presses “A”, which activates the UA, or like taking the phone off the hook to get a dial tone. The VoIP software then creates an off the hook event that is entered into the FIFO database located within the UA. The special OpStartCall operator receives this new event, processes it accordingly, and takes that call to the dialing state. The caller then enters the phone number and when finished dialing, the Dialing Complete event begins. At this time, the OpInviteURL operator sends an SIP Invite message to the VOCAL system for the call to be routed and forwarded.
Once the VOCAL has finished routing the call and the call begins to ring, eventually, the call is answered on the other end. The VoIP Software then sends an SIP 200 “okay” message to the caller to indicate the call session has started. The OpFarEndAnswered operator then processes that message, taking the UA to the InCall state. Now, the call remains in progress until one of the individuals hangs up. When this happens, the phone is once again in the “on-hook” status. All of these operations working together create a calling experience very similar to a normal phone call.
