It depends on your application and your understanding of the constrains you will be facing...
PVDM2-16 contains only 1 DSP and as you might have known, you cannot do both conferencing & transcoding on the same DSP module; so if you wish to implement both on the same router, you will hit a bottleneck. Also with only 16 available g711 channels and 6 if you enable the high-complexity codec or 8 if you chose the medium-complexity; you might not even have available channels to enable conferencing or transcoding depending on the number of PRI timeslots already enabled. I was having the same problem with the PVDM2-16 on one of my 2811; where I could not complete or test some labs scenarios because of the limitations on the DSP, initially I thought I could manage by utilizing resources in the other routers, but after a while of cutting corners, I bit the bullet and upgraded to PVMD2-32.
