Granite Delivers Complete TDM-to-Cloud Communications Suite Under Merged Voice Brand

Granite Telecommunications has announced the availability of Granite Merged Voice, a complete communications suite that includes Granite’s proven TDM and hosted voice services to help organizations today and as their needs change and grow.

Granite Merged Voice services encompass key solutions along the path from POTS to cloud communications, including:


Plain old telephone service, including analog lines, digital trunking and PRI services, enables companies to use traditional phone systems for local and long-distance calling.

Emulated POTS

This service allows companies to use existing analog phones for Voice over IP (VoIP) calling over any access connection.

SIP Trunking

A replacement for PRI enabling companies with existing on-premises private branch exchange (PBX) phone systems to make and receive VoIP calls.

Direct Routing

Companies using Microsoft Teams for collaboration can use Direct Routing via SIP Trunking to make and receive VoIP calls to the public switched telephone network (PSTN) from the Teams app.

Hosted PBX (HPBX)

HPBX delivers always-updated office phone capabilities as a fully hosted and managed cloud service, so businesses no longer have to buy or manage an on-premises PBX.

Unified Communications as a Service (UCaaS)

An upgrade to HPBX, UCaaS offers features like chat, video, “find me, follow me”, whiteboarding and more over any internet-enabled device to office, mobile and remote workers.

Contact Center as a Service (CCaaS)

This cloud-based solution allows companies to enable sales and service reps to interact with customers through voice, email, social media and the web from virtually any internet-enabled device.

Granite Merged Voice also can be purchased with Granite Guardian, a comprehensive managed network solution that safeguards business connections and improves quality of service (QoS) for critical voice and video calling over data connections.
