In order to use our service, you must have a device with a static IP address or DNS name that is capable of receiving SIP calls. Some examples include IP-PBXs, SIP Servers, VoIP Gateways and IP-Based IVR systems. When you submit your order, you need to provide us the IP Address(es) or domain name of your equipment. We will then route all of your access numbers (DIDs) to the IP Address that you have provided and call you to perform a test.

A channel is a virtual phone line or virtual connection between your equipment and ours that allows a single phone call to pass through. If you have multiple channels, you can have multiple calls at the same time. All our DIDs come standard with 20 simultaneous channels.

A DID is a phone number assigned to you to operate your service. When your customers call this DID from the PSTN, our system instantly routes the call to your system.

SIP (Session Initiation Protocol) is the signaling standard for real time communication including VoIP. SIP is open standard which allows a logical connection between an IP PBX and a Service Provider’s application servers that allows voice over IP traffic to be exchanged between the two.


Theoretically, there is no correlation between the number of DIDs that you have and the number of channels that you can have. Our DIDs come standard with 20 channels. If you need more that 20 channels then we can give you buy additional channels for $1 each. For example, if you need 30 channels then you pay $10 extra per month for your DID.
