Features

Phone System Co-location

Co-locate your phone system in our data center for security and business continuity. Colocation also puts your phone system right where your SIP services are, so there’s less latency and better voice quality.

Auto-attendant & Voicemail Box

Should your phone system or network fail or possibly doesn’t support auto attendant you can take advantage of our AA or VM in the cloud to provide uninterrupted services to your callers.

SIP Edge Router

Our SIP edge routers reserve bandwidth for voice so call quality is maintained even when bandwidth utilization exceeds available capacity.

Call Screening Capabilities

Setup anonymous call rejection, which will automatically block calls from private, unknown and anonymous numbers. You can also enter specific numbers to be blocked using selective call rejection.

Advanced Call Routing

Prepare your entire trunk or any DID’s for “unavailable call forwarding”. This allows your callers to reach an emergency phone number, answering service, cell phone etc. during a phone system failure or network down event.

Emergency Notifications

Provides an extra level of safety and protection by notifying people in your organization via phone and email when someone makes a 911 call.
