Conditions
•Hardware Requirement: An optional Caller ID card.
•The PBX relays text messages from the SMS centre to
•To receive SMS information, you must subscribe to the telephone company's Caller ID service and enable Caller ID for the appropriate outside (CO) lines through system programming (
Caller ID [900]).
•Each 
SLT Caller ID [628]).
•If an SLT user sets the Automatic Callback Busy feature by dialling "6" because the selected line is busy when he or she tries to send a text message, the SLT will ring when the line becomes idle. To send the text message, the user must answer the callback ring, go
•When a call is received on one of the outside (CO) lines preprogrammed in an SMS Routing Table, the destination SLT may ring one time.
•If a user wants to receive SMS messages on an SLT, it is recommended to not connect a proprietary telephone (PT) in parallel. If the PT user answers the call, the SMS message will not be received.
•When an SMS centre call is received at an SLT that has set the Call Forwarding (FWD) feature, the FWD feature will not function and the SMS message is received by that SLT.
•When an SLT user makes an SMS centre call, in some cases the duration of the call may not be verified with SMDR (
1.20.1 Station Message Detail Recording (SMDR)), because it takes very little time to send SMS messages. To verify the duration of these calls, it is recommended to set the start timer of call duration to "5 s" or "Instantly" through system programming (
Call Duration Counter Start [204]).
•When a user on an SLT that is in "TONE (DTMF)" mode makes an SMS call using outside (CO) lines set to "Pulse" or "Call Block" mode through system programming (
Dial Mode [401]), if the SMS centre number is longer than supported, for example 16 digits, the SMS call may not be completed. In this case, set the dialling mode of the SLT to "PULSE" mode using the switch.
