Improve ivr routing for phone dialins.

[liske]

I had some problems with the default dialplan extension for phone callins:

• if the caller enters a 5 digit pin but no conference was found by the pin he gets dropped
• if the caller fails to enter a valid pin (read: 5 digits) three times in a row he got dropped, too
• if the caller enters the correct pin he is directly placed into the conference without any further indication which might feel irritating

The patch changes the ivr sequence this way:

• BEGIN: play the conf-pin.wav only once
• query the pin, on syntax errors use conf-bad-pin.wav to ask the caller to try it again
• after three failures transfer the call to BEGIN again
• if a pin was entered and a conference has been found:
  • playback conf-welcome.wav and join the caller into the conference
• if a pin was entered and no conference has been found:
  • playback conf-bad-pin.wav
  • transfer to BEGIN again

IMHO this improves the usability for dialins since the caller is no more silently dropped or transfered.

I like you're PR, but isn't it wrong at this place? This is for documentation. I think your PR belongs to https://github.com/bigbluebutton/bigbluebutton/pulls. Could you correct this?

And maybe you could have a look at this Freeswitch-dialplan issue: https://github.com/bigbluebutton/bigbluebutton/issues/9161?

So where do I find the 2.2 documentation sources? The _pages/install.md is just a symlink to the the modified file.

Check out the file 2019-02-15-install.md -- I'll update the symbolic links so they are pointing at the right items.

The correct file is 2019-02-14-customize.md, isn't it? I've updated and rebased the PR.
