I am going to visit Astricon’2018 and made chan_unistim channel talk – https://astricon2018.sched.com/event/Fmlx/unistim-channel-past-and-present. In case of anyone would attend this event it’ll be great to meet and discuss any topic you like.
There is fixed issue, that cause chan_unistim do not free RTP ports resources on every call. This fixed in latest asterisk 13 and 14 codebase. Also patch provided for correct call hold implementation.
There was a bug with MWI lamp off after headset up. Now it fixed, thanks to Daniel Bohling. Also error changed to warning in case translation file does not exists on hdd. RTP initialization moved to unistim_request, so strange ast_obj2 …
Hopefully after long development and review chan_unistim driver in asterisk trunk was updated
