Why am I having trouble receiving calls from the customers of other local service providers?
In some areas, Charter customers may have been temporarily unable to receive calls that originate from third-party providers. Federal regulation requires that all local service providers coordinate network resources so that customers can make and receive calls from all providers. In some cases, local providers may not be as active in complying with this requirement as Charter is. However, Charter is working diligently to assist other providers in this respect. If you are aware that customers of other providers are unable to reach you, please contact Charter.
