Enhance recall on busy management

SebastianMB-IT commented 2 years ago

As actually implemented on the NethCTI the ROB is correctly working though needs some enhancements. The request made by the client must be done using only the main-extension and the server must check if the extension to add already exists in the recall queue.

Steps to reproduce

1 - Inside the NethCTI select a device with extension different than the main 1 - Book a call and note that when the called becomes available and the recall starts, only the previously selected extension rings

2 - Book a call to the same user more times and note that every time the called becomes available the caller receives a call until the extensions in recall queue end

Expected behavior

1 - The client must use ever the main-extension as caller when the user books a call 2 - The server must check if the caller extension extension already exists in the recall queue

Actual behavior

1 - The client uses the extension of the selected device as caller 2 - The server don't checks if the extension already exists on recall queue
