DIDX CTO Kamal Panhwar explains, “Phone numbers are available in different directories and sometimes such information is revealed. There are many companies that spam their messages on Whatsapp numbers. If I have a Google Voice number (always a +1 US number), I can set it up as my WhatsApp number and send someone messages that way. This is true no matter where I am in the world. Now the person who receives my messages, that person has the option to report any of those messages to Whatsapp… as spam. Once the receiver reports this, it is up to Whatsapp to deactivate my number.
“It is easy also if I buy a DID number from, for example:
“At the same, there are some libraries in PHP that can still connect*. Hope I am clear. I welcome comments and requests for more information. I actually ran several tests in the past week to make sure the information I am sharing is correct.”
*This means there are some open source PHP libraries which can connect, but the programmer is not updating them to the latest version. For some professional people, these libraries can connect and send a message to WhatsApp, and others can’t.

Traditional speaking, Direct Inward Dialing(DID) is a service of a local phone company (or local exchange carrier) that provides a block of telephone numbers for calling into a company’s private branch exchange (PBX) system. Using DID, a company can offer its customers individual phone numbers, one for each person or workstation within in the company. Even early on, some local phone companies began to provide multiple numbers on one single telephone line. This very concept started to gain momentum when even CLECs began to provide these numbers by routing them on a SIP server. SIP (Session Initiation Protocol) is a protocol used in VoIP communications which enables users to make/receive Voice and Video calls over the Internet instead of through traditional telephone lines.
When DID(Direct inward dialling) is transferred via SIP, it becomes boundary-less. This means, for example, if your USA number you have purchased for your communications service customer is routed on SIP, it provides the possibility to ring on any device that is linked to the Internet anywhere in the world. This is where SIP gives the big boost to DID numbers. When a call routes on a SIP server, it can be handled in any way and transferred in many ways. It can even be controlled programmatically. The voice can be transcribed, digitized, recorded and replied back to by using Text to Speech software, for example. So that is just one example. There are numerous, exciting use cases for this technology.
IAX is also a protocol created to save bandwidth. It lets multiple SIP servers connect together. SIP is very famous and has received more attention than IAX. Even people who do not have much technical education dropped the acronym VoIP and began talking more about SIP. IAX is a very good protocol for connecting servers to servers. That does not mean IAX cannot be used on the client side, but commonly SIP is more famous for connecting with clients.
Note: In Europe, DID is referred as DDI(Direct Dial in). There is also a growing number of people who define the acronym “DID” as direct inbound dialing.
