Voice Services

best of both worlds

Replacing old technology with new can be cost-prohibitive and difficult to deploy. Those with on-premises phone systems have had to forgo the benefits of sophisticated advances like VoIP (Voice over Internet Protocol). Until now.

Crocker Voice Services are simple, highly affordable solutions that merge old and new telecommunications technology, enabling you to enjoy the best of both worlds—old infrastructure with benefits of new technologies such as enhanced performance and reduced overall costs. Two examples include our SIP (Session Initiation Protocol) Trunking Service and Digital Voice Line.


With Crocker SIP Trunking Service, the Internet connection you currently use for data can be used to carry voice transmissions from your existing premises-based phone system. This service enhances your telecommunications infrastructure with such cost-saving VoIP benefits as shared access, bundled minutes, private voice network and reduced hardware components.


Also called VoIP Dial Tone, Digital Voice Lines are designed for legacy, premises-based phone systems at small- to medium-sized businesses. Providing seamless voice connections to the Public Switched Telephone Network (PSTN), Crocker VoIP Dial Tones serves as direct, cost-saving replacements for Verizon POTS (Plain Ordinary Telephone Service) lines.

During our recent conversion of the City of Greenfield’s phone system from multiple, diverse premises-based PBX’s to a unified town-wide Hosted PBX solution, Crocker’s team displayed strong project management and problem solving skills, in particular as it relates to Public Safety’s complex call recording requirements. They always responded rapidly and professionally when any issues surfaced.

After installation and initial training on our new VoIP phone system, I was hit by a barrage of questions well beyond my comfort level. So I called Crocker Customer Service and spoke with Tim. Tim was patient, supportive and clear in his instructions. I needed process explanations in simple step-by-step terms and that is what I got. As new questions arose among the staff I went back to Tim several times and each time he was as patient and “sympathetic” and effective as the last.

The technical team at Crocker has been very responsive to our needs. The system is very deep – we only scratched the surface of it in the beginning. The Crocker team has helped us maximize the capabilities of the hosted phone solution. They have also been very helpful in the rare event where there was a problem with the system.

Having Crocker for our broadband provider and our telecommunications provider has been the best thing to happen to this little town in a while. The Crocker sales representative went above and beyond when helping us discern what we needed within our municipal buildings for equipment as well as service. Technical support has been friendly and more than capable. Crocker was a great choice for us.
