Open ITSP List

Welcome to the Open ITSP (Internet Telephony Service Provider) list, a directory of ITSPs who have registered with DIDWW and have opened their network for free incoming voice traffic. This is very attractive feature that allows customers to enjoy the benefits offered by VoIP communications.

The names of all listed ITSPs are directly integrated into the DIDWW’s distribution network websites and ordering wizards, providing visibility to the ITSP and promoting their services.

This directory is free of charge to all ITSPs and is open for listing, updating, downloading and synchronizing. The Open ITSP list is rated according to the number of DIDs that are forwarded by our infrastructure to each listed ITSP.
