Adhearsion crashes on sending cyrillic to FreeSWITCH

[utgarda]

Hello! Trying to get Adhearsion working with FreeSWITCH and Russian TTS on flite. FS is built with flite, en & ru.

adhearsion.rb :

# encoding: utf-8
...
  config.punchblock.platform = :freeswitch
  config.punchblock.password = "ClueCon"
  config.punchblock.host = "127.0.0.1"
  config.punchblock.media_engine = :flite
...

FreeSWITCH output:

> freeswitch -version

My default terminal encoding is UTF8, just checking before starting ahn:

Same thing for non-interactive controllers.

I'm digging into this a little hoping for a fix, but in the meantime you should update your gems (bundle update) since you're behind on a few (RubyFS and Celluloid for sure).

[benlangfeld]

This is pending getting the RubyFS specs passing again (they appear to be timing out due to some dependency update) and a test case on RubyFS (a pull request for which would be awesome) for this specific issue.

[benlangfeld]

RubyFS test suite should be passing again now, so the next step is a failing test case for non-ASCII commands/responses.

Closing in favour of adhearsion/punchblock#201
