We use the power of the cloud to deliver business phone service over your existing internet connection.
The power of the cloud
Cloud phone services combine your phone system and extensions, long distance service, and technical support, creating a predictable, per-extension, per-month model.
Costs for business phone service can be reduced significantly due to the removal of physical phone lines to maintain, and having calls routed through the cloud instead of those physical lines.
GreenLink is proud to offer the most flexible Cloud Phone System solution which enables you to configure your system, your way, to best meet your needs.
We believe in providing the flexibility for a customer to sign up and use their existing IP phones.
