Not strictly speaking a FreePBX thing - more Asterisk - and I’ve been meaning to post for sometime. The male voice artist responisble for en-GB has sadly passed away.
I got in touch with Jay Benham a few years ago wanting to get some new prompts recorded that sounded like the originals - and he was happy to oblige. We became friends and amazingly I found he only lived a few miles from me.
Sad news, but he’ll remain immortal in many Asterisk-based solutions
