Java Script VoipJS Create a SIP connector on the front-end
668 USD 
General description: using the sipjs or jssip library, it is necessary to implement the ability to make calls from the browser to one phone number simultaneously from multiple sip accounts.
(For example, on the page, 4 sip accounts are authorized at once)
In the final version, the completed task should look like this: On an empty page, there is a clickable phone number. The user clicks on the phone number. Each SIP account should start calling the same phone number. As soon as any SIP account successfully connects, all others should be disconnected (stop calling). Minimal visualization for the user is mandatory: Visualize in a modal window the display of which SIP accounts have started calling and a timer. Opposite the visualization of each SIP connection, there should be a button to cancel the call specifically from that SIP account. At the bottom of the modal window, there should be a button to cancel all calls. After a successful connection, when the other SIP accounts are disconnected and only the SIP account that has already connected remains, only one active SIP account should also be displayed on the front end.
Optional request (can be completed as a separate task for an additional fee):
It is necessary to implement call recording and saving on the server.
