We have a client looking for a solution for on call after hours which would queue callers and have them hold while trying an agent's cell phone number. We have attempted to use EHDU in a Terminal Cascade Ring group but the calls ring through the 5 extensions programmed, even though they are not logged in. It doesn't actually call the cell phone programmed, but the timer rings the extension for 20 seconds before moving to the next, so if you have 3 out of 5 agents not logged in, you lose a minute of time It appears that it is looking at the presence status of the extension and if all 5 members are present in the ring group it will still ring them, regardless of if they are logged in or not. If I make them absent from the ring group, then it will not ring them. Any suggestions are appreciated.
