SIP Trunking: How It Works

SIP Trunking replaces your existing telephone lines with a VoIP alternative, but allows you to keep using your current phone equipment! You select the number of office locations, number of phone lines and types of phone numbers.

In some situations, SIP Trunking requires a " VoIP Gateway" device to connect to your existing phone system and in other cases, SIP Trunking connects directly to your phone system. Your Certified Installation Technician will determine the best fit for your phone system.
