Wireless LAN Solutions:

• Wireless LAN (WLAN) technology provides growing companies with fast, secure and easy setup networks.
• Wireless LAN (WLAN) connections offer several advantages over the LAN connections. The benefits are obvious since the user can actually move from one point to another and stay connected to the WLAN (WLAN) connection and its resources.
• The network can be established without placing cables or installing connectors inside walls. This is particularly useful when installing temporary networks or when working somewhere temporarily, changing locations periodically, such as companies that move to bigger offices when exceeding the capacity of the existing facilities.

CANTTEL LTDA.:

• Offers consulting and connection design by specialists optimizing quality and energy saving.
• Specializes in programming and wireless installations.
• Offers support and a 24-hour service.

CANTTEL LTDA.’s connectivity services aim to establish a high-speed network for the transmission of voice, data and video between the branches of the client company, centralizing information on a single network.
 
The total connectivity will result in wireless links in two or more places, depending on the number of the company’s branches. This will ensure the highest level of availability, reliability and information security.
 
With this solution, the client will be constantly connected to high capacity, high quality and low cost wireless connection.

Analog telephony:
CANTTEL LTDA. offers solutions for business phone systems that meet the needs and requirements of the client companies. Panasonic, Intelbras and Cesller’s analog phones provide the necessary functions for voice communications that are optimal and technologically appropriate.
 
IP Telephony:
IP Telephony combines two historically separate worlds: the transmission of voice and data. This means transporting voice, previously converted into data between two distant points. This will enable the use of data to make phone calls and going one step further, the development of a single network that will include all communications, voice or data.
 
This implementation eliminates completely long distance phone calls between different branches. In places where there is no institutional network, coverage calls can be made over the internet.

Asterisk is a very safe, stable and efficient software that runs under a Linux environment. Asterisk is a virtual phone center, mounted on a Linux server.
 
It works through a communications protocol, as well as over the Internet. In fact the client needs to be connected to the Internet to work with IP Telephony. Through Digium, OpenVox and Sangoma the client can connect analog or digital lines and support many simultaneous communications. It does everything a conventional telephone does and much more. The client can actually connect multiple phone types: conventional analog or virtual IP.
 
Analog phones are the cheaper phones available, but they require a voice adapter or gateway to connect to the PBX. IP phones are digital phones that connect directly to a network, while USB phones are very common in the market and they need to be connected to a PC to operate. Similarly, soft phones are software and only require a headset or headphones to make a call.
 
CHARACTERISTICS OF AN ASTERISK PLATFORM:

• Music on hold,
• Voicemail,
• Traffic Reports,
• Keyword Annex,
• Receipt of FAX to PDF,
• Records for all calls, incoming or outgoing,
• Delivery of voice messages to email,
• Use of existing structured cabling CAT 5,
• Wi-Fi Phones,
• Phone-edge management,
• Phone Software,
• Calls to mobile phones using celulink,
• WEB Panel activity,
