I ended up in building the solution myself.
here I publish some work-in-progress details if you're interested:
Also I'll be glad to use my new knowledge for someone's project if there's a
need for a similar solution.

Subject: [swinog] looking for a virtual PBX provider
I'm building a technical infrastructure for a new on-call support service. This will
require a virtual PBX where the support engineers would login and manage the hotline
redirection to their personal PSTN or SIP destinations.
Those interested in providing such a service, please contact me off-the-list, and I'll
send you detailed technical requirements.
