ВРЕМЕ: 2021-11-01 ХИТОВЕ : 2

The VOIP system is based on IP language transmission, which is a voice call technology. VOIP can also be used to include VOIP phones. In recent years, IP technology has developed by leaps and bounds, and more and more products are produced using VOIP technology.

In addition, VOIP is also widely used in the industrial field. The VOIP telephones produced by Нинбо Джойво can be used in pipelines, subways, tunnels, wharfs, highways, power plants and other places. VOIP telephones also play a significant role in anti-freezing, dust-proof, waterproof, fire-resistant, moisture-proof and other fields. Joiwo currently has waterproof loudspeaker telephones JWAT909 and JWAT910 whose protection level can reach IP67. At the same time, there is also a waterproof sound and light telephone JWAT903, the protection level is IP68. In terms of explosion protection, there are two products, JWBT820 and JWBT821.
