However, if your current network quality is poor, Opus can provide you with a better audio quality than other narrowband codecs. Its hearing aid compatible (HAC) handset helps the person who is with hearing loss to hear the voice more clearly.

Furthermore, a unified firmware and auto-p template that applies to all T4U phone models, saves even more time and costs for businesses, as well as simplifies the management and maintenance.

It’s also compatible with leading soft switch suppliers, such as 3CX, and Broadsoft Broadworks. Moreover, it is carried with dual firmware images that give you enterprise-level protection to avoid bricking your system once an upgrade fails.
