With many years of Network Engineering work experience, I'd say it's highly unlikely this problem is caused by a DHCP assignment change. Especially if the only change in your internet connection is outbound voip call quality. I also wouldn't put too much into geo-ip mapping either. ISPs are assigned blocks of ip addresses from IANA and those assignments are not geographically based. Geo-ip location takes extra logic, such as Google's My Location service which requires a browser that supports W3C's Geolcation API. Google also makes use of it by getting your web browser to provide information an wifi access points nearby.
