I have a strange problem with a new Elastix install. When outside people call us via our sip trunk (bandwidth.com), the users don't hear the first 3-4 seconds of our receptionist's greeting. It's only on inbound, never outbound. It doesn't happen every time, but more often than not. She also reported to me that she was experiencing a lot of echo this morning. I've searched all over google and haven't found a solution (only others with my problem). I've taken tcpdump captures of both the outside and inside interfaces on my server and in the captures, I can hear all the audio (wireshark playback feature). I've attached a capture of one of our test calls and here is my trunk config in sip_additional.conf: [bandwidth.com] canreinvite=yes context=from-pstn dtmfmode=rfc2833 host=126.96.36.199 nat=no outboundproxy=188.8.131.52 progressinbound=yes qualify=no type=peer Thanks.
