SIP (Session Initiation Protcol) is a service that comes in on a high speed internet connection. SIP trunks eliminate the need for standard telephone lines and equipment, which greatly reduces the costs of maintaining and servicing telephone system equipment. For these reasons, Sip trunks are a cost effective and highly efficient alternative to traditional telephone services. Customers love SIP trunks, because they cost less monthly and when used in conjunction with our on premise VoIP systems, also reduce new equipment costs. SIP is quickly becoming the new standard for telecommunications service.
