Hi there! We found Markus' draft after a discussion in the SIP area. The problem that we have is to tell a SIP user agent (which is typically a voice over IP phone according to RFC3261) that the access to the Internet has changed (for example, the ISP has changed the IP address) or has been rebooted. In the case of an IP address change, the client must reregister as soon as possible in order to stay reachable from the outside world. In the case of a reboot it is helpful to restore the state in a possibly present application layer gateway in the Internet access device. To me this looks like a problem that potentially other applications (for example, online gaming) also have. Therefore I think it makes sense to use a standard out of the scope of SIP to solve this problem. Practically, DHCP is used in these networks and to me it seems only natural to use the DHCP to solve our problem. Therefore, I support the draft written by Markus. For the problem that we see it would solve the problem in an easy and efficient way. Please continue the good work in this area!
