Hello everyone

First of all and as always we start by thanking the great @Erel for making this possible for us

We made a post asking the lovely B4X Family about what to create next, a VPN or VoIP and most of the votes went to VoIP, so here we are

Today we would like to announce that in exactly 4 weeks (28/03/2021) (dd-mm-yyyy) we are releasing a new amazing project :
VoIP (Voice over Internet Protocol) system, which will consist on the following :
1- Text messages
2- Real Time voice calls
3- Group Voice Calls

Real time voice calls will work locally or publicly (through the internet) by using the SIP technology
The Audio Codec will be : PCMA (G.711)
Supported Audio Codec : h.264 codec

The Project will be built using :
1- B4J System Admin + System Server :
- Managing Incoming Calls
- Managing Outgoing Calls
- Managing Users information
- Able to disconnect any active call
- Calls and text messages log
- Able to record any active call and save the call as a MP3 file
- Able to get any text messages sent/received as save the log as a .txt file

2-B4A Client
- Each client registers will get a unique ID (just like a phone number)
- Speed Dial (able to add anyone to the list by typing the ID)
- Call block (able to block any incoming call from a specific ID)
- Able to send text messages
- Phone book (able to add anyone to the list by typing the ID)
- Calls History

3- B4J SIP Client has been released!

VoIP SIP (Voice Calls) System : Source Code

exactly no, i know they wrote the library from scratch, updated the b4j server, the b4j client and the b4a client, it seems enough to me, I trust Saif, he will have done a great job, as always. Nobody doubts the technical abilities of Saif and his colleagues I think they have demonstrated it...
www.b4x.com

3-IOS Client - Coming Soon...
- Each client registers will get a unique ID (just like a phone number)
- Speed Dial (able to add anyone to the list by typing the ID)
- Call block (able to block any incoming call from a specific ID)
- Able to send text messages
- Phone book (able to add anyone to the list by typing the ID)
- Calls History


More information will be posted once we finish developing feature by feature

The source code will be for sale : 150$
Project Price : 35$ Only

Purchase the source codes :
*If you have any question or you need help please contact us @ : info@b4xcode.com or @ : b4xcode.com@gmail.com and we will get back to you right away.


We have added to list "Features to be added" :
-Avaya integration
As many of you know that Avaya is leading in the field of VoIP so we will add a feature to integrate the features of Avaya in the project which is amazing because with this feature you can transform the call from Avaya phone device to your own server which will give you the ability to :
1- Control and manage the call from the server side (record , log , etc...) (B4J Server App)
2- You can answer the phone call from anywhere in the world (B4A + B4i Client App)

*This is an extra feature to the app meaning the app will not need any Avaya equipment and it does not need Avaya SDK to work, it's only an extra feature.



We will keep you updated

Thank you guys for your support

It's okay it will be our next project after this one

VoIP had more votes that's why we picked it :

Next Big Thing?

Hello everyone :) We are still in the search of the next big thing, and we just had this idea, why not create a VPN app and sell the source code ? i think a lot of users are looking into making their own vpn but as you may know it's not that simple in fact it would take us maybe more than 30...

Thanks, VOIP will require quite an expensive server i think!

Yes it doesn't require a huge server, just a normal VPS

the only two thing that is required to make it run smoothly is :
1- The internet speed of the server (if you want to run it publicly)
2- The bandwidth

As for the CPU and RAM it won't be an issue if the ram was 4GB and the CPU was Intel Xeon E5 (Low CPU)
*You can get a free vps from google (https://cloud.google.com/free)

Sincere congratulations for the new project that you are going to attack
I believe it is a system that will be increasingly used because data transmission lines are now available in most of the inhabited areas, moreover the possibility of using VoIP providers compared to the classic supplies of standard telephone operators allows considerable savings.
Finally, the convergence of the telephone system with the company information system is a natural way to improve the effectiveness of work
Being able to transfer a call that arrives at the office on a mobile phone of an operator who is traveling hundreds of km away is a convenience that once tried is never abandoned.

Yes, I use several bare metal servers that are basically just raspberry pi's but with limits on bandwidth. The limits would be very problematic for both VOIP and VPN but I think I would still try the vpn one...

Because of this feature we have added the support for : h.264 codec , almost all the phones use h.264 codec so it will be easier to integrate any VoIP service in the project.

Would this be also to run as a switchboard to receive incoming calls to one number and do transfers to other numbers ?

For example if a company advertised 1 number , they would get multiple calls on that number which would play a message until the person was free to answer and then divert the call to another user.

I just received 50 Avaya SIP phones from a client to resell , so I am looking for a solution.

Thank you

Hello,

As you may have read in the first post we said the project will have B4J admin system that will control any incoming or outgoing calls.
so once you have that control you could manage messages, waiting list, and any other feature you would like to implement.

And to make it simpler and easier for the developers to understand the concept we will add the waiting list to the :
"Features to added" meaning we will develop it and add it to the project.

Thank you,
Saif
