8 port IP Telephone Gateways

The Cisco 8 port IP Telephony Gateway is an all-inclusive phone adapter analog (ATA) for small-sized businesses that provides enhanced communication by connecting via broadband via the Internet.

Its Cisco SPA8000 features eight RJ-11 FXS ports for connecting analog telephones to IP-based information networks. It also has a single 50-pin multiport connector RJ-21, giving you a second option of connecting when using the telephony gateway in various situations. It also features a 10/100BASE-T RJ45 Ethernet interface that connects to a router, as well as a switch with multilayer.

 Customers can safeguard and increase their investment by using their analog phones and teleconferencing equipment.

It is installed by the user and remotely configured, provisioned and maintained from the company providing the services, each Cisco SPA8000 converts the voice transmission into packets of data that can be transmitted via an IP network. It also uses the common standards for data and voice network to ensure an efficient operation of fax and voice.

VoIP is a shorthand as Voice over Internet Protocol. VoIP is a technology family that allows IP networks to use for voice-based applications like telephony, voice instant messaging and conference calls. 

Benefits and functions:

Voice data is transmitted electronically through the same networks you are already using for the internet. By avoiding traditional telephone lines, basic phone costs are drastically reduced – typically by up to 40% for normal calls and more when calling international calls.

Automated attendants Automatic transfer of calls to voicemails to transcriptions of emails. All of this makes your office communications quicker and more responsive than before. You’ll always be in charge of these features using an easy-to-use online dashboard accessible from any smartphone or computer. It is easy to add features or users, and get the details of usage statistics to aid in saving more.

Components of a VoIP Network

IP Phones – IP phones offer an IP endpoint to voice communications.

Gatekeeper – The gatekeeper offers Call Admission Control (CAC) Control and management of bandwidth, as well as address translation.

Gateway – The gateway offers the ability to translate to VoIP and non-VoIP network, for example, the PSTN.

Application server: These servers offer services like voice mail as well as unified messaging. Cisco Unified Communications Manager Attendant Console.

Videoconference station The videoconference station gives the possibility of participation by users at the end of video conference.

Background

 

When IP phones first came out using Office Communications Server, a common area phone model was not available. This account configuration relied on the Active Directory Contact object, which was not able to use traditional authentication methods. They also could not be enabled for mailboxes.

This is why Microsoft developed PIN Authentication to Lynn Server to provide a method to log in to an existing phone by using contact objects.It was smaller than the typical handset designed for normal users. 

There was a change in the options for devices, however, as newer phones hit the market using Microsoft’s 3rd Party Interoperability Program (3PIP) and there were no longer models designed specifically for CAP-related use cases from one of their partners.
