BusinessCo SIP Trunks interface with all major PBXs. They can be connected directly to the PBX and replace any existing telephone lines.
SIP Trunks can be programmed directly into an IP phone and act as a stand-alone telephone line with its own telephone number.
No need for a telephone handset to make SIP Trunks work. Use a PC, laptop, or a mobile software app that will turn your device into a fully functional phone.
