Hello,
I need some help with setting up the maximum sessions on my conference and mtp dspfarm profiles.
Here is a "show inventory" of what I have:

I'm looking to use the IOS router as both a conference bridge and for mtp resources. I am unsure as to how many maximum sessions to use. Any help would be appreciated. Thank You!

The number of sessions to configure depends on your telephony requirements and also based on your engineering design. Your router seems quite heavily equpped with DSP resources. I belive there is a reason why you have that much DSP. Example. How many conference session are you expecting or do you want to provision for. Each session supports about 8 participants I believe. So if you have 10 sessions then you can have 80 people at a time etc. For MTP its the same. If your engineering need is 10 g729 software MTP session then you configure that. It all depends on your needs / customer requirements
