Do you have caller ID? If so, you probably enjoy knowing who is calling before you answer the phone. On the other hand, if you don’t subscribe to this service, you might not feel you need it or believe it will be worth the extra fee to obtain. Caller number identification isn’t for everyone, and it certainly isn’t a necessity if you own a telephone. However, it can be very useful in helping you avoid unwanted calls, and also makes learning information about unknown callers an easier task, because it provides you with the phone number you need if you would like to conduct a reverse phone search.
If you’re in the above situation, though, you need a service that will tell you the name of the person using the number and their physical address; mapping is important, too, because maybe you want to find exactly where he or she lives. In that case, you need a service that will do a reverse cell phone lookup for you, at nominal charge.
If you subscribed to a toll-free number service just for this purpose, and you achieved what you wanted by finding and reporting the individual, then you can discontinue the toll-free service at any time. Most do not require a contract.
VOIP is also rich with features, features that cost you noting extra. You have Call Blocking, caller ID, Voicemail, 3-way calling and in some cases more. You can take your contacts off the computer and ad them to your VOIP account. Since it is a virtual service, you can have as many virtual numbers as you want without installing more lines. VOIP is rich with features which makes it a better choice for your home and your business.
How it works is pretty simple. TrapCall reroutes your unanswered blocked calls through a 1-800 number, then back to you. Anonymity is denied to 1-800 numbers, so TrapCall picks up the number as the data moves through their servers. According to a Wired test, the rerouting process only took 6 seconds on AT&T-and during that time all the caller hears is standard ringing.
The list of acceptable source phone numbers is created with the isdn caller command. Luckily for us, this command allows the use of x to specify a wildcard number. The command isdn caller 555xxxx results in calls being accepted from any 7-digit number book number beginning with 555, and rejected in all other cases. We’ll configure R2 to do just that and then send a ping from R1 to R2. To see the results of the Caller ID Screening, debug dialer will be run on R1 before sending the ping. I’ve edited this output, since the output you see here will be repeated fire times – once for each ping packet.
Make suggestions. If you must verify spelling, lend a hand where you can. Instead of “How do you spell that?” or “Would you mind spelling that for me?” prompt callers with your best guess: “Is that Neal, N as in Nancy, E-A-L?” If correct, your caller need only respond with a quick “Yes!” and if not it’s just a hop, skip, and a jump: “Actually, it’s N-E-E-L.” Some virtual receptionists keep a phonetic alphabet on-hand for just these occasions.
The reverse phone lookup is simply a matter of entering the complete telephone number, including the area code, that you recorded from your Caller ID. The reverse phone site will then provide you with the name and address associated with the telephone number. From there, you can take the action you need to stop the harassment in its tracks.
