[Serusers] STUN and public ip address change

When testing with X-lite and GPX-2000 behind NAT using only STUN for NAT 
traversal we loose registration and calls fail if the public ip address 
changes i.e. if the ISP is assigning with DHCP. The reason it fails is 
because the UA's fail to recognise the change in public IP and continue 
to use the old IP.

Just wondering if anybody has suggestions to avoid this (other than use 
an RTP proxy) and/or experiences with UA's which have a STUN 
implementation which solves this.
