Digital IP-Phone communication system
A VoIP phone or IP phone uses voice over IP technologies for placing and transmitting telephone calls over an IP network, such as the Internet.[1] This is in contrast to a standard phone which uses the traditional public switched telephone network (PSTN).
Digital IP-based telephone service uses control protocols such as the Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP) or various other proprietary protocols.[2]
it’s sound quality is compared to none, it has ability to enable communication in large organization and multi states business that require constant office to office communication, with it deployment over the internet your staffs or users can make calls across different states for free without the need for any additional cost
Anaolgue Intercom Phone System
An intercom, also called an intercommunication device, intercommunicator, or interphone, is a stand-alone voice communications system for use within a building or small collection of buildings, functioning independently of the public telephone network. Intercoms are generally mounted permanently in buildings and vehicles. Intercoms can incorporate connections to public address loudspeaker systems, walkie talkies, telephones, and to other intercom systems. Some intercom systems incorporate control of devices such as signal lights and door latches.
Intercoms are used on a wide variety of properties, from houses that only require one connection between a resident and the property’s entrance to multi-unit apartments that require intercom hardware to be installed in every individual apartment. Some are equipped with video, and its wiring (electrical installation), can be connected to the outside with few pairs (4-6 pairs) while controlling an electric strike.
IP - Phone Common functionality and features
- Caller ID display
- Call transfer and call hold
- Dialing using name/ID (differs from speed dial in that no number is stored on the client)
- Locally stored and network-based directories
- Conference calling and multiparty calls
- Call park
- Call blocking feature.
- Support for multiple VoIP accounts – the phone may register with more than one VoIP server/provider.
- Accounts are usually set and memorized on the phone itself. A more sophisticated feature is dynamic download of account settings, also known as “extension mobility”. This feature allows settings stored on a server to be downloaded to the phone, based on user login. The user logs into the phone and that phone becomes the user’s extension. This feature requires both a client (phone) and a server, usually in the context of unified communications systems.
- Secure encrypted communications
- Call to GSM network using connected gsm gateway wireless terminal device
Difference Between IP intercom System And Analog Intercom System
IP intercom systems have more new and practical features. For example it allows video call with voice, while the analog system cannot support duplex communication for voice and video between rooms.
The video quality for IP system is also much more stable regardless of the distance of the terminals, as long as the Ethernet network is stable. But the video quality of analog system will get poorer when the distance is longer. So for long distance video transfer, video amplifier is needed.
- Less limitation for IP system
For analog systems, there is not only limitation on the distance between the terminals, but also limitation on images for each room if no more amplifiers are installed. Also it’s not possible to have video call between rooms.
There are a still variety of helpful convenience and entertainment options on IP intercom systems like playing music, setting alarm clocks, changing ringtones for different rooms etc. Welcome to check with your IP intercom system integrator for more detailed information.
Difference Between PBX and IP PBX
A PBX (Private Branch Exchange) was developed to provide large companies a cost reduction in their telecommunications bill by letting them handle their own telephone system while still providing a trunk line for calling outside the companies network. An IP PBX (Internet Protocol PBX) is an improved version that brings the PBX systems into the 21st century. The single most significant feature addition to IP PBX is VoIP support. VoIP lets companies route calls over the internet reducing costs even further, especially with long distance calls. Since an IP PBX system is designed to work with packet-switched networks, it is also capable of handling data and can even synchronize with outlook.
The internal operations of an IP PBX have also been converted to software instead of hardware, like the older PBX systems do. This makes IP PBX systems so much more flexible than older PBX. The consistent improvement of microprocessor technology meant that they are now much cheaper and much faster to implement. IP PBX are also more scalable compared to traditional PBX systems. In older systems, you are limited to a certain number of lines as they are hard wired to the circuitry. With IP PBX, you can add as many extensions as you want but how many concurrent calls can occur is still limited to your hardware‘s capabilities. Upgrading your current IP PBX is also much easier compared to older PBX systems. Adding additional features is also as easy as a software update that is usually released by the manufacturers.
The high price of PBX systems means that most companies cannot just instantly upgrade their system regardless of the advantages. As a result a lot of the older PBX systems are still in use today. But as the aging systems are beginning to wear down, companies have no choice but to replace the hardware. But instead of using the same PBX, most are looking to implement an IP PBX to take advantage of the benefits.
Summary:
1.IP PBX adds IP VoIP support to the older PBX systems
2.PBX can only handle phone the switching of phone conversations while IP PBX can handle both calls and data
3.Most functionalities of an IP PBX is done with software unlike a PBX where it is commonly done by hardware
4.An IP PBX is very scalable while a PBX system is limited to the designed number of slots
5.Most companies are now installing IP PBX systems rather than PBX

VoIP in unified communications
VoIP consolidates communication technologies into one unified system — meaning that VoIP can allow for a number of audio, video or text-based communication methods. This can be particularly useful for businesses, so teams don’t have to work with multiple different applications to communicate with one another effectively.
VoIP creates this network by allowing users to make calls and hold web conferences using devices like computers, smartphones or other mobile devices.
- Higher-quality sound. With uncompressed data, audio is less muffled or fuzzy.
- Access for remote workers. Good for employees who work remotely as they have a number of options to call into meetings or communicate to other teammates.
- Added features. These features include call recording, queues, custom caller ID or voicemail to email.
