VoIP SIP (Voice Calls) System : Source Code

amorosik said:

I do not have an external service of this type
But if I had to do it I would do it with a service of this type Messagenet
Or others like it
Simply by registering on the website it is already possible to obtain a telephone number to call, which will make the connected 'client sip' ring
If the connected 'client sip' was the B4J server, then the call will ring all clients (or some of them) that will be able to answer
With the payment of a little fee, even a minimum of 6 euros, it is also possible to make calls to the public telephone network
Certainly in every country there are several service providers of this type

Important note:
Messagenet is an operator with a general authorisation for providing "telephone service accessible to the public" throughout the Italian territory issued by the Communications Department of the Ministero dello Sviluppo Economico.

Any additional services present on the telephone line destined for number portability will not be maintained.

• Forward to a Phone Number – Forward all incoming calls to your business phone number.
• Forward to IP – Forward all incoming calls to your voice platform IP address. The IP address must be public and static, and your platform should support SIP.
• Forward to Softphone – Use this if your voice platform is not available over the public and static IP address. User credentials are used as an authentication method. Here, the Voice number is used as a user name and you should set up the password. Integration is done using SIP.
• Trigger Number Masking – This is a special case of forwarding a call to a phone number. The number Infobip forwards the call to is defined in a response Infobip receives from your platform as an answer to our number masking API request. The Number Masking feature guarantees security and anonymity. Refer to Number Masking for more details.

I put it as an example because it has agreements with telephone companies and has SDK's, messageNet only works in 8 countries.

I can not understand you
What authorization are you talking about?
What sim card are you talking about?
If I want to connect my sip client to a voip service provider to call/receive calls to/from public telephone network, I do not have to request any authorization, nor do I need to have sim cards
I register on the supplier's website, buy the credit I need, and then use the data (port_address / user / password) to configure my sip client
By 'client sip' I mean my hardware ip phone, or my software phone (like Zoiper, MicroSip, cc ..), or my voip switchboard (Asterisk, 3cx, etc ..)
We are not talking about replacing a voip service provider
We are talking about using the systems offered by a voip service provider
To do this no authorization from the telecommunications department is required, nor the use of particular api (except those necessary to communicate using the sip protocol)

if that helps...

...For example in Greece... https://www.modulus.gr/
giving info for their API... if you call them - but it is very "difficult" if there is no native support from the same the language or from a sip/pbx library...

Ofcourse at this site you can pay for outcoming calls... to all the world... there is no any restriction.... you can get telephone numbers too

But please read the following (i am feeling that making you feel bad)

I know that all requests you get sometimes... are so difficult for a small team... a person... may be for JAVA too
+ That is the problem ----> at first posts of your Projects... you said give me what you wanna add... and will be add at next updates... but some "updates" are impossible - maybe is the Java limits or the knowledge (have in mind that you are example-pattern for all of us in forum and never want to put you on the wall - sorry if now saying our opinion)

It is better to take the requests and someway answer at first post after a lot of thinking them if it is possible to do it or not (do not answer - that will add it soon) - you are not forced to do them (you will sick)
Some updates that you will think will always welcome... and make us happier..

There is a greek "saying" ---> as far as the feet can go

And I am adding again ---> Saif you already broke the rules/limits - you are the best and your creations too... ☮ ?
