Conditions
• Hardware Requirement: An optional Caller ID card.
• The PBX relays text messages from the SMS centre to SMS-enabled SLTs, and vice versa.
• 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 SMS-enabled SLT must be programmed to receive Caller ID information through system
programming ( 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 on-hook, and then make an SMS centre call
again.
• 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.
