I configured a FXO trunk port to a Valcom 9964 feedback eliminator. When I dial the route pattern associated with the FXO port on the Gateway there is about a second delay then I recieve a fast busy tone. If I sh call active voice compact I see the following...
462 ORG T22 g711ulaw VOIP P 10.82.4.95:21720
461 ORG T22 g711ulaw TELE P
464 ORG T0 g711ulaw VOIP P 0.0.0.0:0
463 ORG T0 None TELE P
The 0.0.0.0:0 call is the FXO. If I watch that port it just blinks green for a split second then turns off.
