CUCM software voice conference bridge

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.

Thanks experts

Thanks for confirming that the software bridge streams can be variable sizes.

Is it correct that you create specific bridges (ie: b1, b2, b3) and allocate specific maximum streams to each, or is it more dynamic than that?

I understand that the MeetMe sofkey initiates the conf call, but my question is more from a scheduling / reservation standpoint from an employee perspective...

Say I have a call coming up in 2 weeks w/ ~8 people and need to send out an invitation with the call in number, etc. I assume we're not having people initiate by pressing the MeetMe button 2 weeks in advance? So, how would I go about 'reserving' that bridge? Or can everyone have their own MeetMe number and the bridges are basically transparent to employees so long as stream resources are available?

It is on-demand allocation, you don't need to specify the size of the conference before hand.

No capabilities to schedule the reservation of the resource. What you may want to do, is restrict access to the MeetMe number so that just the initiator of the conference can access the route partition assigned to the number.
Your help has saved me hundreds of hours of internet surfing.
