I have two Merlin Magix systems connected via PRI. At the remote site they have no LS/GS trunks, they strictly dial out over lines off main sys. When you dial 9 to access an outside line and dial the number there is about a 6 or 7 second delay before you hear any ringing. The dead air causes users to hang up and issues with faxing. What system settings if any would affect this.
