ULTATEL SIP Trunk Service

Reach your customers anytime and anywhere while enjoying cost savings with our SIP trunk service.

Why SIP Trunk?

SIP stands for Session Initiation Protocol. SIP trunking moves your voice traffic through a network that’s powered by the internet.

If you want to eliminate various restrictions from your existing phone and be able to make international calls, reduce expensive equipment, and always stay connected to your customers, your business will benefit from SIP trunking.

SIP Trunking Benefits

Save Money While You Scale
