[Freeswitch-users] E1 hangups

Hi. I'm trying to correct this behaviour, but can't figure out, where is the problem. Here's the scenario: - we're trying to execute simple dialplan * answer * play sound * wait for 3 seconds * hangup - for SIP caller it works as expected - problems are when, we try to call into it from E1 line - for E1 we're using sangoma winpipe & openzap - dialplan in freeswitch console is done in a moment ending with hangup - on the E1 line I hear nothing and after 2 seconds it disconnects - similar problem when there's only bridge to another number (E1) - it rings (on the destination phone) for a short moment (0.5-1s), but then hangs up spontaneously Thanks for any clues. mZubac
