Collaboration Solutions Set

• High availability: the ability to backup when part or all of the equipment fails, or when the system is shut down for routine maintenance.
• Save on long distance connection costs: companies or organizations that apply IP Telephony can reduce intercity or international phone charges for calls over PSTN.
• Information ensures smooth: connected devices can detect problems in the transmission line and switch to other transmission lines, ensuring that the communication between the two ends is always maintained smoothly.

The outstanding advantages of IP Telephony system compared to traditional PBX system:

• Softphone: is software running on a PC providing the functions of a phone. This service helps users to set up calls, answer the phone while still working on the computer.
• Meet-me Conference: is a regular and periodic conference service. The members automatically access the "conference room" at the agreed time without having someone in charge of connecting.
• Web access: via IP phone to get XML information on that Web page. This Website may be a Web site containing internal information of a company such as price updates, policies ...
• Mobile user: this is an extremely effective feature for employees wishing to travel regularly. From the company's branches around the world, through the WAN, the employee can subscribe to the company's IP Telephony network to use the phone service as if they were at their regular workplace me.
• Expansion services: IP Contact center: IVR, ICD, CTI ... customer support systems, automatic answering allow today's businesses to better support customers in a competitive environment.

3. The basic components of the voice system based on IP
3.1 Central switchboard components
Call handling center Cisco Unified Communication Manager (formerly known as Cisco CallManager or also known as IP PBX) is the center that handles all voice calls for IP Telephony network. Cisco Unified Communication Manager enhances the capabilities of IP voice networking through network devices such as IP phones, media processing devices, VoIP gateway equipment, and multimedia applications.
Furthermore, Cisco Unified Communication Manager allows the distribution of all IP phones, gateways and applications over an IP network forming a Telephony IP network with all designs ranging from single, distributed or virtualized. (virtual). The number of users that Cisco Unified Communication Manager manages depends on the hardware as well as the software structure with the maximum number of tens of thousands of phones and Voice devices.

3.2 Voice Gateway System
Voice gateway provides communication between different types of Voice control signaling protocols. For example, Voice Gateway provides communication between Voice systems using H.323 protocol and PBX systems using other protocols through a protocol conversion system. Provides connectivity of IP Telephony system to PSTN systems, traditional PBXs or connects to analog phones or fax machines.
Cisco Voice Gateway products are usually divided into two types:

• Analog Gateway: Here are two common types of Analog Gateway devices:
  • Analog station gateway devices provide connection between the IP Telephony network and a traditional post office phone system (POTS).
  • Analog Gateway devices connect to trunk lines, provide interfaces between IP Telephony systems and PSTN CO switches, or connect to other PBX systems.
• Digital gateways: The digital gateways are also devices that provide communication between IP Telephonyh network systems with PSTN networks or PBX systems through digital trunk lines. 

3.3 Gatekeeper System
Gatekeeper is an H.323 device providing call control service to endpoints and transferring addresses between E.164 and phone list. Gatekeeper will manage the inbound and outbound bandwidth between centers and between zones. Gatekeeper will provide the following services:

• Address translation: transfer E.164 address and phone list
• Manage incoming and outgoing calls to each region and each member company
• Support unlimited number of sites.

The terminals (for voice service) will be configured to automatically search for the gatekeeper (gatekeeper discovery) through a sending multicast gatekeeper request (GRQ).

3.4 Endpoint System
Terminal communication devices include desk phones and voice software installed on the PCs and each of these devices has Ethernet connections. Details of the equipment are as follows:

• IP telephony allows direct IP calls.
• Software IP phones: these are voice applications installed on the user's PC and have all the features of the phone such as call tracking, dial-up….
• Video Terminal: including camera linked to a computer, fully compatible with Cisco Unified Communication Manager. When the user's PC is physically connected to the Cisco IP phone, the user can make video calls.
• Wireless IP phone: allows wireless voice link with other devices via wireless network according to 802.11 standards.
• Mobile phones: in addition to support for receiving and making calls from normal GSM networks through Simcard, these phones also support Dual-mode (with wifi support), then through wifi In the building, these phones subscribe to Cisco Unified Communication Manager and become desktop phones and every employee can go anywhere in the wifi zone without having to miss a call when someone calls. to your desk number.

4. VoIP deployment models
There are currently many models for implementing Unified Communication Unified Communication, but any unified communication system must be based on a call center device, Cisco Unified Communications Manager. This is the central processing system for the entire Unified Communcation system of Cisco.
Here are some models of implementing IP Telephony systems based on the platform:

            

Single Site Model
A single site Cisco Unified Communication system deployment model consists of a call center that is uniquely located on a site. IP Telephony services will not be available over the WAN environment. For this deployment model, all equipment serving the IP Telephony system including PBX system, voice gateway system, Endpoint system is located at a central site, voice data will be concentrated. at a single point.
Single Site deployment model will provide high availability, the ability to utilize the available network infrastructure. When using the Single Site model, the system can completely use the G.711 Codec standard for voice services, because the voice data does not have to go through the WAN environment, where there are many limitations on the tape problem. information.
However, when deploying the IP Telephony system under the Single Site model, VoIP services are concentrated at one point without the distribution of branches or other transaction offices.

Multi-Site model with centralized call center
Multi-Site deployment model is designed according to the principle of having a call center located at the headquarters, providing VoIP services to remote sites connected to via IP WAN infrastructure. The WAN network is responsible for the transport of VoIP traffic between the central site and the remote sites. Remote sites will rely on Cisco Unified Communication Manager system deployed as Cluster to use services such as Voice Mail, IVR (interactive voice response). These applications are usually located on a central site together with Cisco Unified Communication Manager to reduce administration and maintenance effort.

Distributed call processing multi-point communication model
This model is only applicable when a Cisco Unified Communication Manager Cluster is not large and powerful enough to support the entire system either due to geographic or organizational conditions. This model consists of the Cisco Unified Communication Manager cluster connected to each other through the H.323 trunk. Each Cisco Unified Communication Manager Cluster will then include Cisco Unified Communication Manager, gateway, gatekeeper, MCU, endpoint, and applications. In addition, QoS service quality management must be applied to WAN connections between sites.
