Difference among Phone Numbers: Landline, Mobile, VoIP, Tollfree, National

Landline numbers operate on PSTN over copper phone lines. Remember our childhoods when we had a party line and the phone set was connected to a cable that connected through the wall of the room and from there through the phone lines on the telephone poles? Landline numbers are traditionally linked to a specific device like a landline phone set or traditional PBX. If people call your landline phone number, you will not hear your device ring if you are not near enough to it. As silly as that sounds, it’s true. If your landline phone number linked to a phone set at your office in Panama City, and you travel to Istanbul, you won’t receive made to it unless you pay your traditional phone company exhorbitant per minute charges for call forwarding.

Cell phone numbers (aka mobile phone numbers) operate over cellular networks through handheld devices.

VoIP phone numbers operate on VoIP networks. It is an identifier used to place phone calls. VoIP phone numbers look and act like regular phone numbers on the surface. The set of digits are spoken to or entered on a dial pad and then connect two or more people to talk. People carry their VoIP phone numbers with them no matter where they do in the world. VoIP phone numbers look, on the surface, like they are associated with a certain area code. To a VoIP network, there is not much difference among local, national or international numbers…because again, we note that you can received on your VoIP number no matter where you are on planet Earth. If you have a Tokyo, Mexico City, Bangkok, or Manhattan area on your VoIP phone number, people can dial any of those five VoIP phone numbers, and you will receive the phone call on the device that you have set for it to be received. You could be in Canberra, Paris, or Harari, and still receive that phone call.

What’s so great about VoIP phone numbers is that incoming calls can ring on more than one device you own at at one time, so you can receive calls in the most convenient way for you. You an have VoIP phone numbers ring on an IP hard hand set, on a SIP client, on a mobile app, or on a special gadget meant for enabling you to receive phone calls on your laptop or tablet. Because VoIP numbers do not have to be linked to a specific area code or city, they are also called virtual phone numbers or virtual phone lines. VoIP numbers follow the “owner” wherever she or he go. This offers the highly empowering feature of mobility!

Tollfree phone numbers (aka freephone numbers) are phone numbers that are billed for every single phone call made to them. The person or organization that owns the tollfree phone number pays that bill, not the people who dial the tollfree phone number. The person who originates, from a landline or even some mobile lines, the call to a toll-free pays zerio charges. People and organizations that own tollfree phone numbers have them so that their current and potential VIP (customers, colleagues, vendors, etc.) can place phone calls to them free.

National numbers are phone numbers that are not geographically-specific. They are available with a goal to make a person or organization reachable from anywhere in a certain country. No matter where an entity is calling the national phone number from, the cost will be no different. National phone numbers are available in many nations, but not in the United States or Canada. They are used by people and organizations that want to make it affordable and easy for their potential and current VIP (very important people) like customers, colleagues, and vendors.

How does SMS figure in? Customers can send SMS (aka text) messages to any of the above phone numbers and phone lines, only if they are “SMS enabled.” In turn, businesses can send SMS messages in to reply to the customers.

Our DIDX team plans to share a Facebook Live talk soon by DIDX Business Development Executive Moeed Alam,  in which the topic will be about different kinds of phone numbers on the DIDX Facebook page.

DIDX VP Interviews Anthony Minessale II and Brian West of the FreeSWITCH Project

Thousands of customers and vendors that participate in DIDX wholesale direct inward dialing marketplace use open source communications solutions like FreeSWITCH, OpenSIPS, Kamailio and Asterisk. Anthony Minessale and Brian West, co-founder and General Operations Director, respectively, staff and huge worldwide developer community played and still play crucial parts in why and how DIDX enables the globe with wholesale direct inward dialing.

iMiller Public Relations’ Ilissa Miller, Kamailio’s Daniel Constantin-Mierla, TMCnet’s Rich Tehrani and Peter Dunkley contributed the questions and topics that DIDX discusses with Brian West and Anthony Minessalle.

lissa Miller, CEO of iMiller Public Relations
1) OpenSource and OpenCompute projects are changing the way companies develop solutions (such as FreeSWITCH) –
what is a key driver for the development of your platform?  What problems does it solve?
2) How are you leveraging the open compute initiatives to develop the platform capabilities?
Asipto and Kamailio’s Daniel Constantin-Mierla
1) It’s now more than 10 years since the start of the project — with the experience accumulated now, but going back when you started the project, would you do something different?
2) What are the biggest challenges you faced or still face as an open source application that tries to disrupt the rigid and somehow walled garden market of telecommunications?
3) Freeswitch has outstanding support for video conferencing and webrtc. Are these technologies going to change radically the way we communicate? How do you see their impact to residential users as well as enterprises?
4) Can you give some numbers regarding the performances of Freeswitch as a video conference system on a commodity server these days (e.g., price range 2-5000USD, 2-4 CPUs, 8-16GB memory)?
5) How is the performance affected when running on virtualized systems, what are the characteristics of the virtual machine that impact the most?
Rich Tehrani, TMCNet CEO and director of the popular ITEXPO, AllAbouttheAPI, and IoT Evolution and other tech conferences asks:
1)      How did you come up with the idea to launch FreeSwitch?
2)      As the product has evolved – what accomplishment(s) are you most proud of?
3)      Are there any specific geographies or markets most suited to FreeSwitch?
Peter Dunkley, Director of Product Management – Telephony at NewVoiceMedia
1) For the features that are the same as they were as many as ten years ago at the beginning, why have those survived the test of time?
2) A few years ago WebRTC was a hot topic, now people talk about RTC (encompassing more than just audio and video), where does Freeswitch fit with this new (beyond next-generation) technology?
3) Traditionally Freeswitch would have been installed in the “owners” data centre or machine room.  Today everyone is moving to the cloud.  How well does Freeswitch fit into this new deployment model?
4) More and more enterprises and individuals are using technologies like Skype, Skype for Business, Slack, etc.  A lot of these technologies do not require organisations to deploy or own anything, some push a lot of (what used to be network) functions into the client.  What benefits does Freeswitch bring to organisations using these technologies?
5) More generally, what are the biggest three industry developments or changes you’ve observed in the past 10 years? Which industry initiatives and technologies have proved to be over-hyped?
