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
