SIP Trunking


SIP Trunking

As the major telccos have retired their legacy TDM networks, SIP Trunking has become the defacto standard for modern Enterprise communications, but this doesn't mean it's reduced the complexity. 

Running SIP Trunks in an Enterprise environment requires a lot of upfront work to ensure the toll quality voice you've been accustomed to with TDM networks is replicated with SIP Trunking. Wide area network (WAN) bandwidth and quality of service (QoS) are required to optimally
support Enterprise voice. 

At Vocio we help our clients design, procure and manage SIP Trunks from a portfolio of the largest providers, AT&T, Verizon, Lumen, BCM One and numerous other carriers.

What clients are saying


"After going through three different service providers and running into the same problems, I was thrilled that Vocio was able to get it right the first time."

"Managing Telecom charges and information can always be a challenge. Most companies don't have the benefit of accessing the data from one location. The staff at Vocio designed a dashboard that tailored not only to my needs, but created logins and limited access views for other co-workers that shared a need to view this data. The staff at Vocio is knowledgeable, efficient, and handles even the smallest request as a priority."

Ray R.


"For over four years Vocio has provided us with excellent service. Most recently we were charged over $5,000 for Internet usage on one of our cell phones. We believe it was a faulty phone but after several unsuccessful calls to the carrier I called Vocio and explained what happened. They asked me to send the bill and within 24 hours we had received a full credit. It was very impressive."
