Tom Waterman Posted May 14, 2009 Report Share Posted May 14, 2009 Is there anyway the PBX would prevent a call from coming in? Here is my setupo. I have an older T1 that comes into an AUdiocodes Mediant 1K. I can make 2 calls at the smae time with no problem. On the 3rd call the caller receives a fast busy. It does not make any difference if it is 3 calls coming intot he system or one in and 2 out or 3 out. It is the addition of the 3 call that causes this. Here is what I see in the Gateway. SIP/2.0 500 Line Unavailable<013><010>Via: SIP/2.0/UDP 10.130.1.236;branch=z9hG4bKac388051577<013><010>From: And then the reorder tone is played. Any help would be greatly appreciated.

Tom I just got a response back from the gateway support folks and this disconnect is coming from the PBX side. Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted June 1, 2009 Report Share Posted June 1, 2009 "500 Line Unavailable" means the trunk uses CO-lines (see http://wiki.pbxnsip.com/index.php/CO_Lines) and all lines are in use. Quote Link to comment Share on other sites More sharing options...
