We're looking at rolling out the latest business edition of Cisco Unified Communications Manager 5000 series appliance paired with a 2911 voice gateway.

Per docs- table 22-2
http://www.cisco.com/en/US/docs/voice_ip_comm/cucmbe/admin/8_5_1/ccmsys/a05confb.pdf
Software conference devices support G.711 codecs by default. The maximum number of audio streams for this type equals 128. With 128 streams, a software conference media resource can handle 128 users in a single conference, or the software conference media resource can handle up to 42 conferencing resources with three users per conference.
Caution If the Cisco IP Voice Media Streaming Application service runs on the same server as the Cisco CallManager service, a software conference should not exceed the maximum limit of
48 participants.

Question 1- can the streams (48 in our case) be configured in bridges of any size so long as the max streams is not exceeded? ie-
Bridge1 - 24 max participants
Bridge2 - 16 max participants
Bridge3 - 8 max participants

We've been told that it is either 1 bridge w/ upto 48 partipants OR 16 bridges with upto 3 participants.

At 48 total participants, the upper bound will rarely be an issue for us, but we're concerned with the process of schedulign a Meet-Me call a few weeks out and being assured there will be enough resources and that the dial in information that would have been sent out will be accurate.

Question 2-How are people typically handling the directory numbers for Meet-me conferences? Treating it like a resource reservation seems logical to us, but we aren't using a cisco system today, so we could be missing something. Please share your insight.
