Grandstream Systems

Many Grandstream systems previously supported by Unitel have been classified as end of life by the manufacturer. Customers should begin planning to upgrade or replace these systems.

Munger Technical Services or another qualified local VoIP provider may assist with replacement options and future support.

System Backups

Unitel’s automated backup services will be discontinued during August 2026. Customers should work with their internal IT staff or technology provider to establish a replacement backup process as soon as possible.

Software Subscriptions and Renewals

Customers with Sangoma or Digium software subscriptions should contact Munger Technical Services or Sangoma Cloud Support to confirm their current coverage and arrange future renewals.

A system will not normally stop operating solely because a software subscription has expired. However, updates, support, security services, and certain features may become unavailable.

Open Invoices and Account Questions

Existing invoices, outstanding balances, and questions concerning prior Unitel equipment or service charges will continue to be handled by Amherst Communications.
