Estech Systems, Inc. (ESI (News - Alert)), a provider of telephone systems and cloud services to small- to medium-sized businesses (SMBs), announced the successful interoperability of its family of VoIP systems and products with the Session Initiation Protocol (News - Alert) (SIP) trunking solution from Vintalk.

Vintalk provides wholesale, business and consumer IP communication services throughout the U.S and other countries. Through this interoperability testing, Vintalk (News - Alert) will be able to offer enterprise telephony capabilities with cost effective SIP trunking services to ESI users.

Vintalk’s telephony package for small- to-medium business customers includes local, long-distance, conference calling, and SIP trunking services. With Vintalk solutions, businesses can deploy SIP trunks in five business days. The company also offers bundled SIP trunks and international long distance and conference calling plans.

Vintalk’s solutions now seamlessly integrate with an existing ESI investment. The company also offers a free 30-day limited SIP Trunk trial for authorized resellers and their customers.

“We are pleased to receive the certification of interoperability of our SIP Trunking services with ESI,” said Tom Judkins, vice president of Sales & Marketing for Vintalk, in a statement. “To celebrate this collaboration, we are offering a free 30-day Vintalk SIP Trunk trial for ESI Certified Resellers and their customers.”

 ESI Communications Servers deliver standards-based technology, advanced features and highly differentiated applications in a flexible, easy-to-use, and cost-effective package, according to company officials. The company also provides customer service, support, and training to Resellers.

“This certification substantiates the seamless integration of ESI’s phone systems and Vintalk’s SIP Trunking solution, providing business customers with the confidence that they have reliable telephone service and equipment,” said Jason Hearon, director of Sales for ESI, in a statement. Earlier this year, ESI  demonstrated the new Android (News - Alert) based ESI 250 Smartphone for reseller partners.
