DNS name in QR code instead of IP Address Email Template - GS Wave


Is it possible to have the fully qualified domain name (fqdn) inserted in the Email sent by the PBX with UCM account information? My ISP changes my IP address very frequently. I have Dynamic DNS setup for my site. Everything works great with GS Wave when I scan the QR code until my IP address changes. Then it no longer works. If I edit the account in GS Wave and change the SIP server to the fqdn it works great. It is easy for me to do this. However, I would like to avoid having to do instructions to tell my users how to make this change. Please advise. QR Code configurations sure make it a lot easier.
