Phone Line over IP technology is now included as standard in all new Business Flex packs. In practice, this mean that everyone who opts for a new Business Flex can make calls on a HD phone with excellent digital sound quality.
You already have a pack with Phone Line and you also want to benefit from this excellent sound quaility? Then call our customer service on 0800 55 500 or visit a Proximus Shop to switch of charge to Phone Line over IP.
Your calls go through your modem instead of the traditional voice channel. Since voices are first digitized by the HD phone, they’re transmitted almost undistorted. So, ideally, all callers should have a HD phone to get the most out of the quality.
Calls in digital quality don't cost more than normal calls. The standard Phone Line rates remain applicable. And the HD phone itself is not expensive: you can get one for just €49.58 (VAT excl.).
Do you want to benefit from this excellent sound quality on your fixed phone? Then call our customer service on 0800 55 800 or visit a Proximus Shop to switch free of charge to Phone Line over IP. A Proximus technician will come by to install this technology (and, if necessary, a more recent modem) free of charge. Your can still use your current phone but to make calls in HD you will, of course, need a HD phone.
No. A call with IP technology has no impact on the internet volume.
If you don't have a telephone exchange, these devices can be directly connected to the "b-box 3V+" modem (2 ports possible).
For an alarm that uses the landline as a communication channel, we recommend you equip the line with a UPS battery (battery backup b-box 3V+) to prevent power cuts.
Phone Line over IP phones have to be connected to the electricity grid. To guarantee the functioning of devices for which continuity of voice and data connection is crucial (alarms, surveillance lines, etc.), we recommend you equip your modem with a battery (battery backup b-box 3V+). This battery ensures Phone Line over IP continues to work by providing one hour of electricity on a "b-box 3V+" modem and an optical-fiber modem (OLT: Optical Line Termination). To guarantee the functioning of your telephone exchange, we also recommend you opt for a UPS battery (Uninterruptable Power Supply).
In the rare cases where there no DSL access or optical fiber is available (less than 5% of Belgian territory), Proximus will continue to provide a traditional PSTN telephone service in the years to come.
