Not sure why you mention "from DID to SIP"one is a phone service/feature and the other is a protocol.

You can have DIDs in SIP

Hi Sameer

This document will give you little insight about CUBE (ip-ip gw) and how to set it up.

You can check the interop guides from the link that I added initially and see if it covers your ISP. They are usually comprehensive.
