PVDM2-32 with one E1. I have no free dsp to create HW conference resources. Max sessions is 0. Is there a way to find out where my dsp's are allocated? I have alot of efxs ports, but i dont know what they are. fxs are analog, dont know what efxs is. thanks

efxs is the ephones. These don't actually use anything. You can try reducing the timeslots on the PRI if not using all.

many things you can do to view your dsps, usage and availability:

first, if your E1 uses all 30 channels, then you have ZERO dsps available to use for anything else...you must get more dsps.

if you use only 28 channels or less, you have at least one dsp to use for other purposes.

you can view your dsp allocation with 'show voice dsp group all'

you can verify how many dsps you require for your needs with the dsp calulator if you do not know how to calculate them yourself
