When setting up an account in the Android app and entering the Host option for the domain that is setup on our SIP server, the app rejects the host input with a message that says "Invalid Fully Qualified Domain Name". This only occurs when the host itself has an underscore ( _ ) in the domain. I am seeing this on the Android version and not the Windows version; however, I do not have other devices that I can test this with. Any input would be appreciated or a patch to fix this would be even better.
Please let me know if you need me to clarify further.
