[asterisk-dev] Module Deprecation, Default Not Building, and Removal

[BJ Weschke]

I don’t think anyone would have suggested beginning any process of removal of the chan_sip module when development of chan_pjsip first began. In fact, the discussion and decision of deprecation of chan_sip didn’t come about until AstriDevCon 2018 which occurred nearly 27 months after that July 2016 milestone.

>>> Four years, is indeed, really long. I do agree with this. As an example, I work with another project where the work involves some integrations with software that is in the head units of vehicles. Right now, they’re working to certify and lock down code and functionality for the 2023 vehicle model year which will hit dealer lots for the first time in just about two years from now. Once final certification occurs, in the vast majority of cases, nothing changes and the vehicles roll off the assembly line with the integration that was certified. If software that is involved in the manufacturing of vehicles can manage change risk within a two year window, it only seems reasonable that the Asterisk project should be able to do the same.

The answer could be its fine. I don't really have a concrete answer though at this moment and likely wouldn't until put into action.
