If the Communications System is operating in Key Mode and Outcalling is used, you must assign one or more outside lines to the MERLIN Messaging System ports (extensions) used for Outcalling. You must also set the lines to No Ring on these extensions, as described in the next procedure, to ensure proper operation. These procedures are not necessary if the Communications System is operating in the Hybrid/PBX mode.
For MERLIN Messaging System Release 2 or later, the port(s) used for Outcalling are Port 2 when a 2-port card is installed, Port 4 on a 4-port card, Ports 5 and 6 on a 6-port card, Ports 7 and 8 on an 8-port card, Ports 9 and 10 on a 10-port card, or Ports 11 and 12 on a 12-port card. For Release 1 or 1.1, the port used for Outcalling is Port 2 when a 2-port card is installed, Port 4 on a 4-port card, or Port 6 on a 6-port card.
