James,
Have you redacted the SIP To URI (sip:612****@10.1.10.10:5060;user=phone) for privacy reasons? If not, possibly there are restrictions enabled for extension 111 in the Options of the extension Managment Console.

James,
You could try removing the extension and recreate it or cross-posting your question to the 3CX forum and ask what Warning: 499 Royal3CX "Not found" means.

Running out of ideas on what to check to fix this.
Have a problem where I can't make an external call on the M85 with a M700 Multicell setup. I can receive external calls though. This is part of a 3CX system.
The odd part is if I register the handset with an extension that already has a desk phone tied to it, I can call out. I've attached the SIP log below.
