VoIP protocols are a group of technologies that make calls possible over the internet in the form of data packets sent from one IP to another. A variety of protocols have been developed to serve different purposes, from transmission of voice calls to sending of fax messages and SMS. Several VoIP protocols, such as SIP and H.323, are the dominant choice today. To cover all requirements of the VoIP business, it is a good practice to use a softswitch that supports multiple protocols and codecs and can convert them. Such softswitches do not limit carriers to establish networks which consist of any type of traffic and destinations geography.
The telecom carrier business is undergoing constant change. With technology advancing and traffic volumes rising every year, carriers must be well-equipped to respond to the changes. One of the most needed instruments for that purpose are the softswitch add-ons.
