I have a OpenVBX/Twilio setup where I use its dial applet to call
particular people in my company. However, when viewing an incoming
call on my phone, I have no way to know if the caller is calling via
OpenVBX or not.

Is there a way to customize
OpenVBX/Twilio so that when viewing the caller’s Caller ID on my
phone, I can see the Caller ID information and some indicator that the
call came through Twilio?

Every time I receive a call from or make a call to somebody in my
contacts list, when I check my call log afterwards there is a call
listed from an unknown caller at the exact same time as the previous
call. This results in an unknown caller always being at the top of my
call log, which isn’t a huge deal, but is kind of annoying.
my searches for the same problem I’m having turn up results about
getting and/or blocking calls from unknown callers, but I am NOT
actually getting these calls.
Any ideas on what is causing this?
Haven’t rooted my phone or anything. Thanks!
Edit: Downloaded the
app Call History Manager, it’s saying the contact name is

Implementing voicemail in Twilio. How can I get a call back if the
caller hangs up before the recording starts?

After the incoming call’s <dial> times out, the
call back URL responds with this:

<Say>Please leave a message.</Say>
<Record playBeep="true" action="http://..." />

The issue I seem to be having is that if the caller hangs up while
the <Say> verb is executing, the
<Record> verb never executes and thus the
application never receives a call back.

Is it possible to receive a call back under this circumstance? If
so, how do I make that happen?

How to Find Out the Number of a Withheld Call

Have you ever gotten a call from an anonymous caller ID? Of course, you have! These pesky blocked number calls are not only annoying but can be a one-way street to a financially damaging scam or identity theft. In the most extreme cases, sinister people withhold their numbers to harass and threaten those who answer the phone.

Getting a threatening call from a withheld phone number can make you feel powerless. Can you go to the police if you don’t even know who’s calling you? How do you block a number that you can’t see? The truth is that getting to the bottom of a blocked number isn’t easy – but it is possible.

Reveal A Blocked Number With Automatic Callback

Blocking a number is as simple as dialing *67, but so is calling that number back and catching the telemarketer who won’t stop offering you a Caribbean Cruise or Florida Timeshare. Most phone providers have an automatic callback service.

If you receive a call from an anonymous number, don’t answer it. Dial *69 to return the call and see the number. If the line is available, your call will go through. If it’s not, the service will actually try to call the number every minute for the next half hour.

Unfortunately, an automatic callback isn’t available in all areas, and sometimes, withheld callers are actually diverting the location of their original call. In that case, it won’t work. Even so, this service usually costs just a few cents, so it’s worth a shot.

Trace A Call If A Blocked Number Is Harassing Or Threatening You

While you may not be able to get the exact withheld number, you can rest assured that the police can figure out who is trying to contact you by tracing the call. Call Trace should only be used in serious situations where someone is harassing or threatening you. Don’t bother local law enforcement because you’re annoyed with telemarketers or hang-ups.

To trace a call, answer your phone and immediately dial *57. You should get a confirmation tone and message if the trace was successful. You’ll receive an error message if it was not. Keep a log of the date and time of these calls or you won’t be able to retrieve the caller’s information. After tracing the call, contact local law enforcement who can work with your phone provider to retrieve the records.

The only downside of Call Trace is that this option isn’t available in every location or with every phone provider. It also incurs a charge which will show up on your next bill.

Use An App Like TrapCall To Discover Withheld Numbers

There are numerous apps around the web offering the service of revealing withheld numbers. Most of them are a total toss up – they don’t usually work. TrapCall has been widely regarded as the preferred unmasking service with features in publications like Wired and The New York Times.

To unmask a restricted number with TrapCall, install the app on your cellphone. When a blocked number calls, decline to answer. In a few moments, you’ll get a call back from the actual number. You can then opt to blacklist whoever is calling.

Sign Up For The Do Not Call Registry

Rather than spending a lot of time or effort figuring out who’s on the other side of a withheld number, you may simply want to sign up for the National Do Not Call Registry. This removes your number from various telemarketing call lists. If you still receive telemarketing calls after signing up, you can report it to the Federal Trade Commission.

How to Uncover Who’s Calling You From Unknown Numbers.

If you own a mobile phone you have at some stage received a call or missed a call from an unknown number, if you haven’t, you’re either lying or don’t own a phone. The good news is there is a way to figure out who these sneaky devils are that lurk in the anonymity of the unknown call.

There is now a way to detect a large portion of calls and texts coming from unknown numbers, using an app downloadable from the Google Play Store. It goes by the Name: DU Caller: Caller ID and Recorder which is a bit of a long name, but I guess they wanted to get the purpose of their app out there.   

If you’re wondering how this all works, it’s quite simple and clever, uses a completely different system to other Apps that claim to identify unknown callers. Du caller is backed by a huge international number database which makes identifying the name or organization of the calls easy. With the basics of DC caller out of the way, let’s have a look at some of the features and how to actually use them.

How to Use the Features of DU Caller: Caller ID & Recorder.

The first feature and the most important one is the Caller ID, this does exactly what the names states, it identifies the caller and shows you the name and address associated with the caller. It also takes this one step further by automatically notifying you if the caller is a known spam caller. For example, telemarketing companies, banks, and insurance providers. It does this by highlighting the name and number in red, however, you will still have the option to answer if you choose.

Apart from identifying callers, DU Caller also allows you to block callers, sounds great, doesn’t it. You can also add custom numbers to the blocking list as you please, simply flick over to the BLOCK tab on the far right of the main screen, tap Blocklist Management, then add a new number. If you ever wish to remove the number from the blocked list, visit the same screen and remove it.

As well as a custom blocking option, Du caller also has a preset list that blocks a range of other numbers. This can be can be accessed from the three horizontal lines in the top left-hand corner, then selecting Settings. (It’s the first item on the menu) Inside the settings, tab you will see the following options.

Common Spammer: Turning this on blocks telemarketers and nuisance callers reported as spam by others. (they recommend using this)

International Numbers: Turning this on does exactly what it says, it blocks incoming calls from international numbers.

Numbers Not In Contacts: Enabling this will block any number that you do not have saved in your phone’s contact list.

Hide Numbers: This will block numbers hidden by the telecom service. (not sure exactly what this one does or means)

Du Caller also has an option to replace your phone’s stock dialer and the contacts app if you decide to do so. Once done it will make all of the above services much more efficient, however, isn’t compulsory. This process isn’t done automatically when you download the app, so if you wish to keep your default dialer, you can do so without any problems.

Something else really cool and maybe creepy depending on your outlook is the option to enable the call recorder, which will allow you to record every single incoming and outgoing call you make from your phone. (This option is available when receiving a call or making one) If you think this all sounds too complicated, the app only has three screens and a simple settings interface. Blocking spam callers and recording conversations has never been this easy.

How to Stop Solicitation Calls on a Voice Over IP Phone

by Andy Walton

Solicitation and telemarketing calls can be a significant problem for your business, causing distraction and wasted time to you and your colleagues. Many VoIP providers allow you to block certain numbers, helping you to prevent regular repeat offenders from calling back. Alternatively, you could invest in a robocall blocker to automatically block calls from automated numbers. You could also sign up to the National Do Not Call Registry, making it illegal for some telemarketers to call you.

Block Number

Blocking the caller’s number is probably the simplest way to stop incoming solicitation calls. Most VoIP providers allow you to configure call blocking either through your VoIP software or by contacting your provider to have the block placed directly. However, blocking a single number in this way is only useful if you know the number of the person who is calling you. If the organization sending you solicitation calls keeps their number hidden then regular number blocking is of little use.

Call Filtering

Call filtering is effectively a more advanced version of number blocking. With call filtering, calls are filtered according to specific rules, such as whether the incoming number is already in your VoIP address book. This allows you to create whitelists of numbers, where only numbers that meet certain criteria can call in to you. However, call filtering can also create its own problems, such as when clients or colleagues call in to the office on a number that the system doesn’t recognize.

National Do Not Call Registry

The National Do Not Call Registry allows you to opt out of receiving most telemarketing calls. Once you add your number to the registry, telemarketers have 31 days to stop calling you. After this time period, companies can face heavy fines if they call you on the number you registered. You should file a complaint with the Federal Trade Commission if you suspect that companies are violating the registry’s terms. However, charities, political organizations and companies that you have a pre-existing business relationship with can still call you, even if you add your number to the list.

Robocall Blocker

A robocall blocker is useful if you regularly receive solicitation calls placed by an automated dialling machine. Robocall blockers are able to detect whether or not a call has been generated manually or automatically and cut calls off accordingly. For example, Nomorobo analyzes incoming phone activity for specific patterns common to autodiallers. If the service suspects that a call might be automated but isn’t sure, it picks up on the caller and asks them to input a PIN number.

Take Sensible Precautions

You can cut down on the number of solicitation calls you receive by modifying your own behaviour. For example, do not pick up the phone if you suspect an incoming call is a solicitation call, as this confirms to the company doing the soliciting that your number is live. If you do pick up the phone to a solicitation call, calmly tell the operator that you are not interested and then hang up the phone. In addition, consider reporting repeat offenders to your VoIP provider, as they may be able to help you.
