The command "srst mode auto-provision all" tells the router that "when you learn info from a phone in srst mode (via SNAP) keep that info in running config." If you desire to keep all that info in running config you also need to keep the command in when saving the config.
Althought I haven't tested it, I would expect that removing this auto provision all (or dn) would also remove the dynamically learned info from the running config but any command you manually typed (such as a hunt list) would stay. If you let srst learn the ephone dn dynamically, then you manually add a description (as in your original question) I would not expect than ephone dn or description to show in running config after removing the auto provision all. The link below discusses the various srst options and gives many cli examples of features you can deploy with cme as srst and using auto provision all. I would suggest revieiwng these config samples to help prepare for the lab. http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmesrst.html I have heard the same advice for srst in the lab from several people: configure srst, test it once and exit, then save and reload. Do not test srst again, trust your config if it worked the first time. The reason for this advice is that the older router code has some bugs and if you try to enter/exit srst multiple times the first will work but it may fail on subsequent tries.
