Both wireless and
wire-line must contend with a variety of different
factors that can degrade the quality of voice communications.
It isn't just about the network coverage and bargain
rates to win customers. If network delays can cause
acoustic echo and other distortions must be dealt
with in order to achieve voice quality.
NMS's family of carrier-grade voice
quality system and echo cancellation meets the requirements
of wireless and wireline telecom operators, deliver
superior clarity anytime, anyway, on any call to every
network, everywhere. These solutions not only eliminate
background conversation, noisy traffic or echo and
network distortion. They improve the quality of voice,
which translates more calls and longer duration of
use.
There are several
reasons why to improve in voice quality:
- Increase
revenue per use: Better
voice quality encourages subscribers to make more
calls and talk longer and that means increase revenue.
- Reduce churn:
The quality of voice service can be directly linked
to increase customer satisfaction.
- Gain market
share: Superior service translates into greater
market share.
- Lower costs:
NMS voice quality systems have low operational costs
because of their low power consumption, minimal
space consumed and high reliability.
- Speed ROI:
It's fast and easy to improve voice quality and
it's inexpensive way to get back returns.
- More competitive
advantage: Offer to subscribers what they
demand and expect, with clear voice quality.
Echo cancellation is an integral part
of virtually every network that supports voice communications.
In addition to echo cancellation, features offered
by these products include:
- Acoustic echo control.
- Studio
Sound voice quality enhancements for consistently
clear calls in noisy environments.
- Signal processing control for flexibility
in mixing voice and data on the same trunks.
- Dynamic speech restoration.
- Tandem free operation (or Vocoder
Bypass) capabilities.
