SIP Operational Telephony
In order to operate, Rail Infrastructure Providers use fixed telephony (beside GSM-R mobile telephony). The VOIP-system will be used by many different types of users depending on the roll they have in the organisation. The station master will need one or more lines to manage the operation of the station. The power dispatcher (controlling the high-tension power on the line) needs to be able to talk with the transformation stations. Most railways also have track side telephones that can be used by track workers or even by train drivers in case of emergency. There will also be telephone services offered to the general public, e.g. an emergency phone on a station platform or in a tunnel. The RideOnTrack VOIP fixed operational telephony system can also be used to connect with the public address systems.

The VOIP fixed operational telephony system is not to be mistaken with an (IP) PBX. (IP) PBX’s are typically used in an office environment and offer many type-of-office features (eg. boss-secretary function). These type-of-office features are not supported by the RideOnTrack solution as they have no use in an operational environment.
