life in 2025 when the <a href=\"https:\/\/business.bt.com\/insights\/digital-transformation\/uk-pstn-switch-off\/\" target=\"_blank\" rel=\"noopener\">public switched telephone network (PSTN)<\/a> is due to be retired. <a href=\"https:\/\/exa.net.uk\/business-services\/voip-phone-systems\/\" target=\"_blank\" rel=\"noopener\">Voice over Internet Protocol (VoIP)<\/a> will predominantly replace this service and will therefore become the mainstream way of making telephone calls particularly in a commercial environment.<\/span><\/p><p><span style=\"font-weight: 400;\">VoIP is simply a way to make calls over the internet, rather than using the conventional landline. It works by taking your analogue voice signals, turning it into digital data and transferring it over your internet connection.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">VoIP is a cost effective alternative to a normal phone line; it has lower network infrastructure costs because it utilises your existing internet connection. You may also benefit from advanced features depending on your provider such as call dashboards, conference call functionality and application integrations.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6d88040 elementor-widget elementor-widget-heading\" data-id=\"6d88040\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">VoIP Services<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-13207f4 custom-posts elementor-widget elementor-widget-text-editor\" data-id=\"13207f4\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">You may be familiar with WhatsApp, FaceTime and Facebook Messenger which are all types of VoIP application. These services are generally for one to one communication and require the participants to use the same platform. However the key difference between these apps and VoIP services is that they do not incorporate the public telephone network and therefore cannot be used as a like for like replacement for a landline telephone.<\/span><\/p><p><span style=\"font-weight: 400;\">Commercial VOIP services will generally refer to two technologies, hosted private branch exchange (PBX) or session initiation protocol (SIP) trunks.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2ac582a elementor-widget elementor-widget-heading\" data-id=\"2ac582a\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">SIP trunks<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3b88fc0 custom-posts elementor-widget elementor-widget-text-editor\" data-id=\"3b88fc0\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">SIP trunks are, in the simplest terms, virtual phone lines that run on your internet connection. You will still require a phone system (PBX) at your premises which must be compatible with SIP trunks in order to make this a viable option. Due to the fact SIP trunks rely on physical infrastructure at your premises, they still have some of the disadvantages associated with traditional phone systems.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">A downside of SIP trunks is that because the system is based in your office it isn\u2019t compatible with remote working. Homeworkers can\u2019t take the handsets home to use as they wouldn\u2019t connect to the service because it isn\u2019t cloud-based.<\/span><\/p><p><span style=\"font-weight: 400;\">They can be a cost effective solution if your existing PBX supports the use of SIP to transfer data, as you do not need to have a licence for every single handset at your premises. However, if your system isn\u2019t compatible then it can be expensive as you will have the responsibility of setting up and maintaining a PBX box on your premises.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8c57b33 elementor-widget elementor-widget-heading\" data-id=\"8c57b33\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Hosted PBX<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a4dc462 custom-posts elementor-widget elementor-widget-text-editor\" data-id=\"a4dc462\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">As the name suggests, a hosted PBX service replaces your on site phone system with a cloud based solution. The service is managed via a web browser-based portal and there is no hardware on your premises other than pre-configured handsets.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">Hosted PBX services work on a licence subscription basis so you will usually pay a monthly fee for each handset you have on site. A key benefit of a hosted service is that if your power went off your service wouldn\u2019t be affected because it\u2019s in the cloud. It\u2019s also far less disruptive and much easier to deploy, basically once you receive your new handsets you plug them into your internet connection and they\u2019re good to go.\u00a0<\/span><\/p><p><span style=\"font-weight: 400;\">A major plus for a hosted PBX service is that it is completely flexible and can be used anywhere. So, if you have remote workers you can provide them with a handset and the phone will work in the same way as if it was still in the office.<\/span><\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-190ce26 elementor-widget elementor-widget-heading\" data-id=\"190ce26\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Which one should I get?<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b649de custom-posts elementor-widget elementor-widget-text-editor\" data-id=\"4b649de\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><span style=\"font-weight: 400;\">As you can see there are pros and cons to both solutions.
