PHP extension Joomla Override JChatSocial extension

Hi everyone, I would need to have an extension override created for my JChat social extension. The problem is that in the video conferencing mode, the call chains are not working to an agreeable UX. I need to have an override inside the joomla template. Current UX: Person A has the conference call with persons B, C and D. Person E then calls Person A. The call chain makes it so that Person E automatically also calls person B, C and D (all of which need to accept the call, meaning that you get disturbed by a constant ringing). UX wanted: Person A has the conference call with persons B, C and D. Person E then calls Person A. Person A then accepts the call. Upon acceptance, persons B,C and D automatically call Person E (without realising that they are calling ie an automatic call chain). Person E then accepts ALL the calls at the same time by clicking on a pop-up that says "do you want to join the conference?". If possible, without that last pop-up then please do so. Please start your offer with "I am the PHP Overlord" . Any offers without it will not be considered.
