Deployment Options: There are two service options to choose from depending on the type of existing equipment you have. Each service provides SIP Trunks which route traffic to the IP Platform.

Next Generation ISDN – Ideal for users who currently have traditional TDM PBXs allowing you to connect your equipment to a Koicoms CPE device,converting traffic from TDM to IP. This is then routed to our IP Platform and you are provided with SIP Trunks.

SIP Trunking – Ideal for users that have an IP enabled PBX (IP PBX) you will connect directly to our IP Platform and you will also be provided with SIP Trunks. Inter-operability testing will be performed as part of the provisioning process.
