# Message Registration Message

Each time a hotel extension makes a trunk call, the system sends a message to the PMS to update the total count of outside calls made against the guest room. No distinction is made between local and long-distance calls. Message Registration works by counting the number of meter pulses made over the duration of the call.

Output Format:

where :

SP = the ASCII blank character

n = the station number digit (range from 0000 to 9999)

The status code in this case is a fee or peg count. This is the one exception to the length of the status code, being 4 bytes instead of 2.

If the system does not receive a proper acknowledgment from the PMS, it generates a hotel log indicating the PMS is out of order. When the PMS is out of order, the system generates occupancy logs for every check in and check out operation. See Occupancy Logs.
