I told that this works. But do you really think it is the good way to go to enforce a Conference URI like "sip:[email-masked]" to be a GRUU? In my opinion, this is a pity, because even if there were many servers in the network example.com having the ability to host this conference (e.g. server could be dynamically chosen according to load before when starting the conference), here GRUU limits the possibility to host the conference on only one server; if the server is not registered, then the conference can not be started. Another case is that, if the server that has the GRUU is removed from network, it is not possible to restart the conference on another server (ie: conference URI has to be delete and re-created).
