const RINGING_SECONDS: i64 = 60;Expand description
How long callee’s or caller’s phone ring.
For the callee, this is to prevent endless ringing in case the initial “call” is received, but then the caller went offline. Moreover, this prevents outdated calls to ring in case the initial “call” message arrives delayed.
For the caller, this means they should also not wait longer, as the callee won’t start the call afterwards.
