Hi Philipp, PK> BUT: There is no guarantee that a SMS message reaches PK> the destination; that's how the SMS network is designed.
That's why we implement higher level protocols that send an "ack" when alarm delivery is vital. If the "ack" fails to arrive before timer expiry, we resend the alarm; it's not rocket science! If the alarm is not service affecting (Eg. information alarm) no "ack" is usually required. "You pays your money and makes your choice". Anyone with limited experience of protocol design, whether the transport is IP, V.24 etc., should be familiar with these basic principles. Other techniques that can be used to implement acknowledged SMS transmissions between IT systems include the use of delivery reports (where supported). As with Asterisk, there are many ways to achieve the same goal, it's more a question of finding the combination that best suits your needs.
