Need ISDN lines installed?

Some people do not have the time to deal with the telephone company business office. Ordering ISDN service can sometimes be a confusing process, especially if you don't speak the "lingo". For a single flat fee DIGIFON will act on your behalf and order the ISDN lines for you. We will contact the local telco ISDN center, specify the correct line configuration, provide the telephone company with the technical data it needs, get an installation date, obtain your directory numbers and spid format, confirm correct provisioning, and cause repairs to be made if neccessary. We will see the installation through to completion to your satisfaction and basically make the process painless. Call DIGIFON at 203-254-0869 and we will take care of it for you.

But....if you wish to order the service yourself, then follow these....
