Freezing

[Hokid]

Looks like this line of code makes all threads froze(blocks entire script) if a call is discarded by calling end so fast(0.5-2s after start):

pytgvoip_pyrogram/tgvoip_pyrogram/base_call.py

Line 134 in 13c0a19

del self.ctrl

And this helps to avoid that:

import time
# ...
del self.ctrl
time.sleep(0)
# ...

I am new in python and may wrong. Can someone to confirm that?
