IP500v2 running 8.0 software. SIP trunking up and running. Inbound and Outbound both connect. When making an outbound calls, about 50 per cent of the time, you get no ringback, the called party answers and you start talking. This does not happen all of the time, but is just frustrating that the outside party answers the call prior to you hearing any ringback at all.
