The patch was written specifically for this site. They took the patch into the newest release that was just sent out. The patch did work on the system co line and intercom calls, but did not help with the ESI-Link calls. Actually, we are now back to square one. It seems when we tweak the ESI, we need to tweak the EnGenius. Trying to balance the two ampified sources to provide clarity across the system on both CO and intercom calls is turning out to be an event that just can't be done! We are now looking at putting a Iwatsu ADIX in to support the cordless phones and remove the EnGenius from the ESI altogether. Obviously, we lose the functionality of having the cordless on the system. What a nightmare.
