Releases for VoIP Drupal

This is a maintenance release containing mostly bug fixes and code cleanup. No major features have been included.

Fixed bug with local numbers and normalization.
Added new hook_voip_number_alter()
Fix for #1944786: Non-English voices don't read non-English characters correctly Non-English voices don't read non-English characters correctly

This release brings important new improvements to the VoIP Drupal platform, including:

* Phone number standardization. Different VoIP providers format phone numbers in different ways, which makes it practically impossible to compare calls with one another. Starting in this version, VoIP Drupal expects call source and destination numbers to be prefixed with either a "+" and country code (ITU E.164 standard), as in "+1 617 222 3333" for US numbers, or with a "sip:" (for SIP numbers). While writing numbers without the recommended formatting might work in same cases, that's not advisable and might generate unexpected side effects.
** NOTE: VoIP Number 2.0 (http://drupal.org/project/voipnumber) provides a common API for handling area codes and other features associated with the new number format adopted by VoIP Drupal

* Advanced SMS features. The new release extends the already-existing VoIP Drupal texting capabilities in many ways. By going to "VoIP Drupal -> Default call configuration"(admin/voip/call/settings) and selecting "Advanced text message options" you will find options to:
** Accept incoming text messages from the SMS framework
** Use the SMS framework for outgoing text messages
** Reduce text message size and server issues by converting special Latin characters (ç, ã, é, etc.) to their ASCII equivalent (c, a, e, etc.)

#1813522 - Fixed %input_digits returns different empty value for different servers
Reverted voipscriptsamples to use '' instead of 'no_input'

This version includes:

* A variety of bug fixes
** Twilio SMS bug
** bug with voipsessions not loading for outbound calls
** label and explanation associated with phone prefix conversion in /voip/call/settings
** bug in voipsession.inc that affected inbound call sessions
** bug that affected outbound calls in Tropo
** #1789272 - Trying to get property of non-object warnings
** #1789234 - variable $channel always NULL
** Changed the return value of addGetInput() from '' to 'no_input'

Welcome to VoIP Drupal Beta 9!

In addition to small bug fixes and code improvements, this version is important for a couple of reasons:

* Default script voices are now handled on a server-by-server basis (issue http://drupal.org/node/1416534). This way, instead of going to call configuration (admin/voip/call/settings) to set up the default voices for the scripts, you will have to do that at the VoIP server level by going to admin/voip/servers/.

Welcome to VoIP Drupal Beta 8!

In addition to bug fixes and code improvements, this version brings a major revamp in the way voices are handled by VoIP Drupal. In particular, Beta 8 introduces a new VoipVoice class (defined in voipcall.module) that can be extended to create new user- and computer-generated voices that go beyond the ones supported by VoIP services.

Twilio now saves recorded files locally, to make it consistent with tropo.
Added new Tropo voices support: http://blog.tropo.com/2011/07/01/tropo-speaks-your-language-24-in-all/
Fixed getInput() bug.
other minor bug fixes and code improvements.

ATENTION: to properly install this release, you will be required to uninstall the existing version of voipcall.module. That will DELETE all the VoipCall instances that you might already have in the system. If you need to preserve your existing call information, please let us know and we will be able to help you out.

In addition to general bug fixes, this version implements important changes in the VoIP Call API and database structure. In particular

Removed dependency on VoipExtension module.
Hangup permissions fixed.
