    Do you need to create a seperate dial in phone number for each external person to use to conect to a UM conference?

    DID extension would work fine as long its defined properly in the OCS.  Dial In Audio Conferencing requires # be configured in proper E.164 format ( as recommended for user externsions as well) and defined Line URI on the conferencing properties in FE.  Once this is defined on the OCS and PBX, the external users should be able to dial in (usually toll free since in many scenarios i have deployed, the callers can call in from any location with no long dist charge).  If you have an IP gateway deployed e.g. Audiocodes Mediant, then you will need to define the 'Tel to IP' inbound route for your dial in conf.

    In addition, OCS R2 Dial In conferencing has dependencies on CWA server since it processes end user PIN/Proxy Auth and Conferencing Attendant and Conferencing Announcement services on FE server.

    Nope. Just one number will work. Assuming you are using a digital trunk to the PSTN.

    Well it depends on how your pbx is configured. usually you create the conference attendant which will give you the settings for the phone number. but then you have to get the number to the conference attendant from the pbx
