CT CLOUD SIP – Lower Cost, More Flexibility

As businesses move away from traditional TDM-based phone systems to an all-IP environment, they will need to embrace SIP trunking as the standard for voice and multimedia communications. This need will only intensify as older phone systems reach end-of-life and require replacement.

CT Cloud SIP trunks include all inbound usage and have 24 concurrent call paths with the ability to scale higher. User friendly web administration through CommPortal for managing the SIP trunk, DID’s, call forwarding and call screening. All of our SIP trunking packages include one local DID with features such as 911, CNAM, directory listing, one toll free number and depending on package size outbound minutes and DID’s without features.

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


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


Operating illegally or offshore, robo calls and unwanted telemarketing calls harass and scam your employees, degrading your quality of service as well while damaging your reputation. Now there’s a simple, cost-effective, solution.


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.


Colocate 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.


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.


CT Cloud SIP trunking customers now have the ability to send and receive text messages between employees and customers through a windows PC or mobile device (IOS or Android)


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.
