mod_voicemail_ivr: Added the new param for API vm_fsdb_pref_greeting_get WARNING, you must add it to the config or else module will complain of missing value... With the new API, it will now playback the greeting when setting it. Will need to figure out a better way to deal with api being added in the future... Add support to auto start new message playback and made it default in the config file.
mod_voicemail_ivr phrases : make value = 0 as plural (0 messages). Don't tell the option for new message if no new message present. Changes a few default key to match more closely mod_voicemail key settings.
Enhancements to trace logging, include threads and context ID.
Changed default opal_conf.xml to allow more than just G.711 uLaw and not to clutter log file with debug logs.
Added to opal_conf.xml item for "disable-transcoding".
Updated build/buildopal.sh to use correct ./configure items for PTLib, allow for something other than standard install directory for PTLib/OPAL and be able to easily bind to a specific release of PTLib/OPAL.
These codecs are non-free which creates issues for distributions, so
let's not require these by default to run our example configs. We can
add back in iLBC once we resolve the licensing situation with our
in-tree implementation.
