The Session Initiation Protocol (SIP) is a signaling communications protocol, widely used for controlling multimedia communication sessions such as voice and video calls over Internet Protocol (IP) networks.
The protocol defines the messages that are sent between peers which govern establishment, termination and other essential elements of a call. SIP can be used for creating, modifying and terminating two-party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. Other SIP applications include video conferencing, streaming multimedia distribution, instant messaging, presence information, file transfer, fax over IP and online games.
We offer many SIP solutions from basic SIP, hosted VOIP and Microsoft Teams.
SIP is a tool not an end all solution for all voice connectivity. Contrary to what you may have heard SIP calls are not free. No one makes a living and no company makes a profit offering free services. SIP services large learning curve for the provider. An inexperienced SIP provider will make your daily communications a mess. A new SIP provider can ground your business to a stop.
