Any VOIP Providers supporting AAC-LD codec?

[uptime1]

If anyone stumbles across a VOIP SIP Provider offering AAC-LD codec, will you please let me know!
Oh, and 3CX, AAC-LD is the highest quality audio with the lowest bandwidth usage, is standards based, great for voice and music, and it's FREE!
It's the same codec that Facetime uses which isn't surprising because Apple doesn't settle for anything but the best.
Thanks!

Hello, In my experience with VOIP I have not seen a provider that supports that yet, and upon doing some research this standardization didn't really pick up hence why its hard to get any one using it except apple. But 722 seems pretty close in terms of bandwidth and compression.
