Is there a way to restore the chan_mgcp module to Asterisk 22?
What is your coding skill level? There is obviously a way, given that it is open source, but it may require significant coding effort, from you.
I am not that skilled. I did however try to see if I could just take chan_mgcp out of the Asterisk 20 version and slot that in to 22, and it seemed to work.
That means your usage of it doesn’t rely on anything in the Asterisk core that has changed. At some point, that will cease to be true, and it may already be true for some scenarios. It’s unlikely that anyone has analysed.
