SIP trunking 
Session Initiation Protocol (SIP) trunking is the use of voice over IP (VoIP) to facilitate the connection of a private branch exchange (PBX) to the Internet.
SIP Trunking enables your business to reduce costs and simplify IT management by combining voice and Internet access over a single Internet connection using your existing IP PBX system.
With Apsystems International SIP service, you purchase only the trunks you need based on the maximum number of concurrent calls your business requires. A SIP trunk is significantly less expensive than analog lines, further helping businesses reduce costs. Apsystems International offers SIP Trunking for single-site businesses and Enterprise Trunking for multi-location businesses.
