Appia Communications, a provider of managed communications and network services, has unleashed the power of SIP by removing concurrent call limitations on its SIP trunking products.

"Call path restrictions do not adapt to customers' changing requirements," said Victor von Schlegell, president of Appia, in a statement.

Schlegell said that customers need their phone services to support marketing campaigns, seasonal changes in workforce levels, cyclical call volumes, and so forth. SIP trunks should enable -- not limit -- customers as these demands arise.

"We continue to simplify our products to address our customers' needs," said Jason Ulm, vice president of channel sales at Appia.

Ulm said that customers get to decide how many concurrent calls to make -- as they need them -- for a consistent and predictable price.

Recently, Appia Communications announced the immediate availability of its new Appia, or Appia Cubed, hosted VoIP offering.

Appia Cubed is a fully managed hosted phone service for companies and organizations. Featuring mobility, scalability, and competitive pricing, Appia Cubed is a complete solution for office communication, without the headaches or expense of managing an in-house phone system.

Appia Cubed is compatible with and auto-provisions Cisco, Grandstream, Polycom and Yealink phone handsets.

Key features of the solution include-Softphone mobility - iPhone (News - Alert), Android, and Windows; Unlimited auto-attendants; Find-me, Follow-me; Customer-managed portal and CRM and Outlook integration.

Earlier in May, Appia Communications had announced the successful expansion of its data center and cloud services at its facility in downtown St. Louis.

Appia will use this managed facility to offer enterprise-class virtual private servers, managed dedicated servers, cloud based storage, and turn-key data center services.

Appia's data center offering includes advanced monitoring of both devices and applications. Administrators are updated about the status of their critical operations via email, phone, or text message. The data center also includes smart hands support.
