Business Internet and Phone Services

Business Internet | Phone Service | SIP Trunking

Office Telesystems can provide your business high-speed internet and SIP Trunk phone services in Dallas Fort Worth and nationally from all of the major carriers. We often pair a cloud or hosted VoIP phone system with business internet such as fiber or broadband for additional bundled savings! We offer the major brands in business internet and phone services, including broadband, fiber and VoIP voice services such as SIP trunking.

For the premise based phone system user, the switch from analog phone lines to SIP trunking is no longer a question of if, but when! In 2019, the FCC removed the obligation for phone line providers to maintain copper analog lines (also known as POTS lines) infrastructure with the goal to utilize new technologies in phone service delivery. The results are not only lower cost options for phone lines with SIP trunking, but better call quality and more options available in your phone system with SIP trunking. SIP trunks will allow your phone system to support both Kari's Law and Ray Baum's Act features. (see middle of our home page for more information)


50% of all copper analog lines will be decommissioned by 2025

Many providers will not accept orders for new analog line service after September of 2024

The price for analog lines is skyrocketing, so you need to move to new services, such as SIP trunking
