I opened a bug report to report confbridge was mixing different announcement languages but it was closed as normal operation.
In short I set announcement language in channel and expected confbridge to inherit the setting but it defaults back to EN and there is no option to set a language in confbridge other than remapping all the announcements in confbridge.conf
Current experience: Users get local language when in the dialplan but after they are the conference all joiner and leaver announcements are in EN
Add a language setting which can be set from the dial plan
Is it tool late to get this feature into Asterisk 12?
