Manually written pages reference old versions of things which are not on the site

There is too many dead links:

1. All links that reference asterisk 12 \ 13 docs, for example: https://docs.asterisk.org/Asterisk-12-Application_MessageSend
2. All links that still reference to the old docs site

You can simply scan docs.asterisk.org with a dead link scanner, you will find a lot

This fix is not enough
90% of the links on the web goes right to the home page.

Example here: https://community.asterisk.org/t/tonescan-in-asteirsk-20/97269

Old link: https://wiki.asterisk.org/wiki/display/AST/Asterisk+20+Application_ToneScan
New link: https://docs.asterisk.org/latest_api/API_Documentation/Dialplan_Applications/ToneScan/

Please file a new issue. This issue was regarding links within the documentation site itself, not externally referenced links. I've investigated trying to preserve external links but haven't come up with a sane way since they don't all match like that.
