connected the sip trunk, calls are made every time but sometimes the caller in response hears only beeps although our operator picked up the phone.
As the provider told us what needs to be replaced SIP/2.0 180 Ringing with SIP/2.0 183/ or ban at all SIP/2.0 180 Ringing
Is it possible to do this or somehow solve this problem ?
