Telephony

Telephony

Good communication on board a vessel means that between the vessel and shore the connection need to be working efficiently. If you think about communication you can think of: Analog long range telephones, high tech conference call solutions and also advanced VoIP telephone centrals. Verhagen IT Group has a lot of experience with all kinds of communication solutions for the Maritime world.

VoIP

Telephony on board a vessel usually depends on a VoIP network. VoIP stands for Voice over IP and means more or less that you call through an internet cable instead of a telephone cable. There are a lot of benefits with VoIP. One of them is the ability to create complex telephone network. Especially with our customers in the cruise market that have a need for complex telephone networks.

At sea it is necessary to use a satellite connection for telephone traffic, because there is no GSM network coverage. Usually a VSAT connection is used to call.

It is possible to connect a VoIP telephone central on a GSM gateway. This enables the ship to call to another ship or shore via a GSM network. However you do need GSM coverage for this.

Our systems are also able to create a phone list. This way the reception can see which cabin called and how many minutes they called.

Analog telephony

Verhagen IT Group also supplies analogue telephone centrals. This is especially interesting if there is no need for a complex telephone network.

Private GSM

Mobile phone network coverage on board of a vessel can be poor. Coverage inside a vessel is due to the metal walls and wiring not always optimal. To solve this you can use a Private GSM network. With a Private GSM network you have strong receivers on board with a strong signal. These powerful receivers have better range and coverage than the receivers in mobile devices, the signal from the receivers are distributed by custom made transmitters.

Public address

To address a large group of people in one instant on board a vessel you can use a Public Address (intercom). A public Address can be used to inform passengers or crew members. These speakers are installed in all public areas and connected to a central system. This way you can address passengers or crew members from the bridge or reception.
