# COLT ONLINE, NUMBERS ON DEMAND AND B2B APIS

We would like to introduce Wholesale customers to our B2B interface: [Colt Online](https://my.colt.net/dashboard/#/), which can be used for unrated CDR delivery for voice services (e.g. SIP Trunking, Wholesale SIP, Voice Line & IN services). 

Here you have easy access to the Unrated CDR guide to facilitate the setup and usage of our tool: [Colt Online](https://my.colt.net/dashboard/#/).

Wholesale SIP customers should now use our Numbers on Demand web interface or our B2B APIs in order to reserve & activate numbers and port-in numbers to Colt. Online help, user guides & video guides are available below.
