Good day all We have a voicetronix openline4 card.Asterisk is configured for sip with all the extensions and all&all. I can call out and internally,to dial out I have to dial 0... My problem is with incoming calls If I call my external PSTN number,asterisk answers with the default message and if I press the extension it goes to the right sip client. BUT As soon as I hangup this call all gets buggered!: If I dial out it plays my answering message and when I try calling back in it doesn't pick up it just rings. Even if I'm in asterisk and do a STOP NOW it just freezes! I have to do a kill -9 Can this be from my ISDN analog line or something Please HElp Thanks Altus
