[Freeswitch-docs] Defunct Provider Configurations

[Ryan Harris]

It seems that the following providers are no longer operating:

FreeDigits

https://freeswitch.org/confluence/display/FREESWITCH/Provider+Configuration%3A+FreeDigits

GrnVOIP/ezcall

https://freeswitch.org/confluence/display/FREESWITCH/Provider+Configuration%3A+GrnVOIP

Free World Dialup

https://freeswitch.org/confluence/pages/viewpage.action?pageId=13174208


Can we archive or remove these? They're just taking up space at this point.
