What happens when voice calls break down into static or loud noises? Users care - of course. Users ditch the service provider with poor quality. Ditech Networks watched users fleeing poor service providers with bad voice and moving to service providers with better voice quality:
1. Ambient Noise–affected up to half of all calls in some regions.
2. Acoustic echo from headset or phone affected 11% of calls and results from calls being made in such small spaces as automobiles.
3. Voice level mismatch, where volume is set too high or too low causing one caller to shout while another is whispering, happens in 28% of all calls.Ditech Networks, a provider of voice quality solutions globally, conducted an audit to measure the level of mobile phone voice quality that currently exists, and found a whopping 39% of all calls were deemed “unacceptable” or likely to cause churn to another carrier. In mature markets, 23% of all calls fell below industry minimums and in rapid growth markets, 59% of calls fell into the same category.
[…] The cost of the churn is estimated at $23.6 billion.– “Why more than 182,420 mobile subscribers a day left service providers”, Carolyn Mathas, Mobile Handset DesignLine
Unified communications means different handheld devices will support voice. In this environment, each handheld guarantees optimal voice quality across all conditions. This means careful engineering for FMC products!
