[Serusers] Hold Status in Mediaproxy session.

Hello List. A quick question for mediaproxy users: What does it means the HOLD status? I see this when i execute the ./sessions command : Caller Via Called Status Duration Codec Type Traffic ---------------------------------------------------------------------------- -------------------------------------------- 200.xx.xx.x:50179 - xx.xx.xx.35:35050 - xx.xx.xx.66:23240 hold (558) 9'48" G723 Audio 49.50k/99.94k/51.34k The call is already over, but the mediaproxy still shows the hold status. Any ideas? Thanks in advance, Regards Ricardo Martinez
