Plain Old Telephone Service (POTS) is the voice-grade telephone service that remains the basic form of residential and business service connection to the telephone network in most parts of the world. The name is a acronym and is a reflection of the telephone service still available after the advent of more advanced forms of telephony such as Integrated Service Digital Network (ISDN ) mobile phones and Voice Over Internet Protocol (VoIP). Plain Old Telephone Service (POTS) has been available almost since the introduction of the public telephone system in the late 19th century, in a form mostly unchanged to the normal user despite the introduction of Touch-Tone dialing, electronic telephone exchanges and fiber-optic communication into the Public Switched Telephone Network (PSTN).

The most attractive feature of a fixed line POTS telephone is that it works even when there is no electricity. Subscribers therefore do not need to have electricity at their homes, offices, or shops to use the phones since they are powered directly from the PSTN by the service provider. Fixed line phones therefore provide greater reliability than other telephony systems (mobile phone, VoIP, etc.). Many fixed line telephone service providers attempt to achieve "dial-tone availability" more than 99.999% of the time the telephone is taken off-hook. This is an often cited benchmark in marketing and systems-engineering comparisons, called the "five nines" reliability standard. It is equivalent to having a dial-tone available for all but less than five minutes each year.

Voix’s Networks fixed-line network has the ability to provide high-quality calls for both international and domestic traffic. The fixed-line network gives a higher call quality than the wireless operators due to the fiber optic backbone and copper last mile infrastructure. Critically, call rates are significantly less expensive via the fixed-line network, as low as 4 cents a minute for international calls and 11 cents a minute for domestic calls.

These rates compare with wireless operators of around 25 cents international and 19 cents domestic a minute. Nigerian market benchmarks indicate an average call revenue per user (installed line) of at least $12.20 per month. On ordering a Voix line, customers pay a one-off connection fee of $84.50 for the installation of the line at the customer’s premises and then pre-pay for call charges. The connection fee covers ‘last mile’ deployment where copper is laid from the nearest shelter to the premises of the customer and the line is installed and activated.

Highlighted below, is an overview of some features of Voix Networks Voice products that stands it out among competition.

Voice Conference

offers advanced conference services for businesses and individuals. Supported services include conferences that are traditional, scheduled, invite-only, private and public. The system supports three levels of conference user roles that include Administrator, Regular Caller ,and Muted Caller. Administrators can manage conference rooms from the phone (Administrative IVR) or via Web (Web console). Two types of conferences are supported: private (PIN authenticated) and public conference. The conference participants may be asked for PIN authentication to enter the conference, if required, or authenticate with Name (conference screening). Administrators can disconnect, mute, and unmute participants via Phone or web at any time, terminate conference, or record the conference and manage the records online or via phone. Scheduled conferences are fully supported based on time or administrator login event. Conferences support private bridging (allows two participants to talk privately), and status services (provides conference status). Conference access can be Service Number based (single-stage) or Extension Number based (two-stage), based on the subscriber profile setup.

Global Roaming

allows global roaming and hunting services for subscribers that need to be non-conditionally reached. The services supports up to 20 phone numbers that will be attempted (hunted) once a call is received. For example, a caller calls the subscriber Service Number, and the system starts to sequentially call all numbers in the Follow-me list. If the subscriber does not pick up the phone on all lines, the call will be forwarded to Voicemail. If the subscriber has enabled the call screening feature, once he picks up the call he can decide to accept, reject, or forward the call to Voicemail. Follow-me is used to achieve two main goals: global Roaming -- allows people with multiple phones to receive calls while travelling, and call screening -- allows subscribers high level of security.
