I can't blind transfer a call that comes in on a trunk as it rings one time and then places the call on HOLD. It works fine on a station to station call. I have one combo card with 1416 and 1408 digital sets. Everything worked fine until yesterday and all of a sudden it wouldn't blind transfer. I checked MANAGER and can't seem to find anything unusual. I have had the system for almost a year and it has worked perfectly. Any help would be appreciated. Thanks
