Lync currently allocates me a random dial-in conferencing ID. Sometimes I'll get a 'friendly' number, and other times it'll be one devoid of nice numeric sequences or patterns.
I'd like the Administrator (or maybe even the user!) to be able to specify their preferred dial-in conference ID, perhaps when the user goes to the dialin page, or otherwise via PowerShell.
Lync should quarantine IDs that have been used before, to protect you from anyone inadvertently trying to join an old meeting.
Choose a more easily remembered code for your static meeting space
Choose a longer, more complex code for a one-off meeting
Longer codes with patterns might be preferred by users and/or execs alike
