Hi, I'm having a problem with one (out of five) FXO line that when a call comes in on that line it just keeps ringing. This line has been working fine up until pretty recently. When looking at the asterisk console output, Elastix seems to think that it answered the call and is playing back the greeting. If there is anyone that had this or might otherwise know what it is, please help. (This may be related to an issue that I've seen in the past in which after a restart calls are not picked up on any line until there is an outgoing call from that line.) Thank you.
