Pause Callgroup Membership/Callgroup Self-Signup

[Ech0klang]

Is your feature request related to a problem? Please describe.
No.

Describe the solution you'd like
It'd be awesome to be able to either sign into a callgroup or pause receiving calls in a callgroup from your Handset. Something like:
1, Call an extension for group management
2. Enter callgroup extension
3. Enter legitimation pin/password
4. Depending on your state you're now either receiving or no longer receiving calls in said callgroup.

Describe alternatives you've considered
An alternative would be to manually manage the callgroup every time a change is needed. This seems rather inconvenient for some use-cases like manning an info-desk and allowing people on-shift to receive calls, etc.

Just in case you didn't know - there is an official API to manage the callgroup membership and state: https://guru3.eventphone.de/api/help

Besides that - we already have this feature on our internal roadmap. Due to your request we will increase the priority and hopefully deliver this on one of the next events.
