I'm coming out from under a rock and jumping from V11 to V15. The V15 is on a virtual server up at Amazon AWS. I tried but could not use the 3cx cloud based demo due to our antiquated mail system, this gets replaced next. We are now a distributed company so this was next best option I could think of. I also could not interrupt the V11 system running in what's left of our main office. I have everyone up on the 3cx soft phone and it is working great. I have a few small sites/users that want their old faithful desk phone with BLF. Some of these are 3-5 user sites, others are a rep at his house. These are all working today as they are on a VPN. What I am seeing is that the provisioning url under the extension (provisioning tab) is for the internal IP of the box up at AWS. Is there a way to change this to the public address? I found a doc on the 3cx site about guidelines on provisioning remote phones but it stops at V14. https://www.3cx.com/blog/docs/provisioning-a-remote-extension/ Is this still possible and would it really require the SBC running at a one user site? Any tips, best practices or suggestions would be appreciated here, I'm still in test mode so an uninstall/re-install is trivial and not disruptive to the operation. Thanks in advance.
