Keep Your Phone System. Upgrade Your Connectivity.
Replace Outdated PRIs with flexible SIP trunking. Better reliability, lower costs, same equipment.
Ready to Upgrade How You Connect?


If your PBX still works, you shouldn’t have to replace it just to reduce costs or add capacity. Legacy PRI circuits cost too much, take weeks to provision, and can’t flex when your business changes.
DQE’s SIP Trunking connects your existing phone system to our fiber network, delivering better call quality and instant scalability without changing phones or retraining staff. Keep what works. Upgrade what doesn’t. Get support from engineers who pick up the phone.

What Makes DQE Reliably Different
Connectivity you can count on, backed by people you can reach.
