VoIP users can now access CRM leads directly from contact-related areas in the softphone, making it easier to connect calls with sales opportunities. The change also generalizes shared VoIP extension points so similar buttons can be reused across related apps.

This commit adds a button that connects the contacts to its leads via the VoIP module. It uses the same logic as "Applicant" button introduced before.
