Blocking Caller ID

There are two ways to defeat the transmission of your phone number to called parties.

  • Call Blocking The first way is to block the transmission on individual calls. Typically by punching *67 (depending on your telephone company) immediately prior to dialing the remainder of the phone number, you can block the sending of your phone number to the called phone. You need to prefix the phone number with *67 each time you want to block sending your phone number to the called party.

  • Line Blocking By making a request to the phone company (in some places the public utilities commission) you can block the sending of your phone number on all calls. If you have line blocking, you may choose to send your phone number to the called party by typically punching *82. This unblocks "line blocking" for that call only.

When you dial (700), (800), or (900) area code numbers you are transmitting your own phone number to the called party. This is because a different technology is used, called Automatic Number Identification (ANI). Calls from a pay phone cannot be blocked. You also transmit your phone number when you dial the 911 emergency number.


A T1 line can provide voice, data, as well as integrated voice and data communications. Many small businesses find this saves money compared to individual phone lines.

A T1 line is a digital line connecting your site to another site, such as the junction switch to the national phone network.

We can provide full T1, fractional T1, multiple T1, or T3 connections at the lowest price available.
