Hi Everyone,

I would like to hear some stories about moving away from proprietary telephony services whether on premises or on cloud to FOSS solutions and how much stable, secure, efficient and cost effective it was.

I would like to present to my managers such cases to convince them to move away from proprietary telephony as it is just huge amount of cost and technical debt.

Thanks everyone and really appreciate any insights, also I am sorry if this is not the place to ask for such!
