SIP powered telephony is paving the way to the new world of Unified Communications.

Published: 17/09/2021

What is a SIP Trunk?

 With a traditional PBX the business leases a high-capacity, multi-call line circuit, often an ISDN, that connects the internal phone system to the outside world via the public switched telephone network (PSTN). ISDN is a service offered by carrier providers offering from 2  to 30 channels. This service is now redundant and will cease service in 2025

Alternatively the business has multiple analogue lines based on the expected number of simultaneous calls during peak call periods. This service will also cease in 2025

A SIP trunk, in contrast, uses Internet protocol (IP) technology to provide the connection to the outside world. SIP trunking is a service offered by an Internet telephony service provider that connects a private business telephone system to a Voice over IP ( VoIP ) service network. The SIP trunking service allows the business to realise the cost-saving,  technological  and  operational benefits  of  VoIP when communicating with branch offices as well as the outside world. SIP trunking can be implemented either with or without replacing the organization’s existing voice network equipment.

Benefits for the Business

Reduced call charges

Reduced capital expenditure - moving onto a single platform that handles both voice and data traffic reduces capital expenditure by a huge margin, both initially and long term.

Lower operational expenditures - SIP trunks allows one converged network for Data and Voice services.

Enhanced employee productivity - through the use of Unified Communications applications.

Enhanced customer satisfaction - through the integration with CRM software, web chat, web based click to call, video conferencing etc.

Redundancy and failover - an  outage  with  the  service  provider  would  leave pstn customers without service for the duration of the  outage.  With  IP-based  telephony voice and data services are automatically re-routed.

What is Unified Communications?

Unified communications (UC) is the integration of  communication services such as :

Instant messaging (chat).

Unified messaging (the ability to remotely retrieve all messages)

Presence information.

Voice (including IP telephony).

Mobility features (including extension mobility and single number reach).

Audio, web & video conferencing.

Desktop sharing.

Data sharing (including web connected electronic interactive whiteboards).

Integrated voicemail, e-mail, SMS and fax.

UC is a set of products that provides a consistent unified user interface and user experience across multiple devices and media types.

Mobile applications - extending UC to smartphones and tablets

UC allows an individual to send a message on one medium and receive the same communication on another medium. For example,  receive a voicemail message and choose to access it through e-mail or a cell phone. If the sender is online according to the presence information and currently accepts calls, the response can be sent immediately through text chat or a video call.

Benefits of Unified Communications

Mobility conecting remote workers, all communication features available in the office are accessible from any location with an internet.

Increases employee productivity using UC for internal communication allows the presence status of co workers to be known and the most effective form of communication to be chosen. eg voice call, email, chat, conference (audio/video), file sharing,

Enhanced customer experience because employees can both communicate and collaborate in an instant they can solve customer problems faster improving the business reputation.
