Asterisk sometimes is confused

Hi. I know that Asterisk works like that.

  1. When sip has incoming call, then it can not do outgoing call.
  2. When the during conversation sip do call outgoing the current call going to the hold.

But in the my log i see some incorrect cases. How it can be?
Sip 185 has incoming call on 16:06:12, but it can be do call outgoing on 16:06:13.

Sorry, but who is sip? You need to be technically more specific, if you expect help. I couldn’t figure out what you are trying to say.

Thanks for answer. But from log file seens that sip is SIP/185.
It 's not possible that at the same time there would be these two things.
Incoming ringing and execute outgoing call.

That’s perfectly technically possible with SIP, even for simple phones.

Can i prevent it with some parameters ?

Salam .) what do you want to prevent tell me

.What is the problem exactly :slight_smile:

give me your sip.conf and extensions.conf for this 2 users
