Searching for Affordable Business Phone Service? Icon

If you're on the hunt for business phone service that is reliable and budget-friendly, Voice over Internet Protocol (VoIP) is your answer.

Today's small-to-medium-sized (SMB) businesses and large enterprises are saving on their monthly communications costs by making one simple decision: to switch to a VoIP service solution from their old, outdated Plain Old Telephone Service (POTS). By choosing a new VoIP service, these companies enjoy the flexibility, reliability, call features, and audio quality that only a VoIP service can provide. Plus, they cut their phone bill by up to 70%!

  • Best MUD engine I have tried, very modern.

  • This is THE best codebase for newbies and pros alike! The ability to modify your mud inside of your browser is an excellent feature and the creator responds quickly to any questions you post in the yahoo group. Try it!

  • An excellent MUD codebase; has all the features you can want (and then some), absurdly easy to administer, and since it's Java it'll run on near anything.
