Setup Aastra Phone outside of office LAN

[gsitsupport]

I am very new to 3CX and I am looking to setup some phones outside of my internal network. I have them with the auto provisioning configured and they register just fine. I can make calls to them from 3CX for Android to the Aastra phone, but cannot do the reverse. I get the below error in the System Log. Any advice would be greatly appreciated. Thank you.

Put the real URL that you've replaced with mydomain.com, in, as the domain name setting in 3CX.
