Microphone and / or speaker sound volume is too low on mobile devices (CL-274)

Observed behavior

If calling via SIP on an android or iOS device, the callee can’t hear the caller very well, because the caller is “too quiet”.

Affected devices

All Android and iOS devices.

Reported by @Robin and confirmed by @voipstack and @a.frankenhauser here and here.

The current beta version of the pascom Client resolves an issue where the sound amplification was disabled despite being connected to a pascom 18+ server.
