when a user make a phone call thru PABX using the VOIP gateway, ocassionally you can hear 2 call progress tone overlapped, after the call established (e.g. one call progress tone gone), the called party still hear a call progress tone while the caller didn't, also, both can't hear each other.

anyone has this problem?
