What technologies and what programming language should be chosen to create a call center operator's workstation?

Question

Java

The management is tired of paying for 1C licenses, and the business is growing, and with it the call center.
The programmers were given the task of writing a "front" or workstation (AWP) of a call center operator to replace the one used. Now it's a bunch of 3CXPhone + Asterisk + FreePBX + 1C 8 CRM + a lot of file work.
I know about AMI, I could write something for the web, but I really want to integrate the sip-client "under the guise" directly into the workstation.
I also know about WebRTS, but, they say, it’s tight with incoming events.
Please advise from experience. What technologies and what programming language should be chosen to create a call center operator's workstation? Can ready opernsors what is?
UPD: After a couple of sleepless nights, I tend to think that this will be my own development with borrowings either in C # .NET WPF or Java c JavaFX. From ready-made sip-clients - linphone - embed into your application as a library liblinphone.

Answer 1

As a variant of TAPI

outcall.sourceforge.net
But then you will have a hard binding to desktop Windows

Answer 2

developed his own workstation - used SipekSDK to embed the softphone into the form and Asterisk.NET as an AMI library. there are no complaints about the libs - tested on systems from XP to windows 10 TP (the latter is purely out of curiosity) Sipek may scare you by the fact that it has stopped developing, but on the other hand it is just a wrapper over pjsip, which are more alive than all the living, and if memory serves is just the heart of the linphone. If you are interested in details - write in a personal
