Typically just leave the complexity the default unless you have a reason to change it. It would only affect conference resources if you built hardware conference resources on the router in question (or transcoder resources) and then put them in a MRG in callmanager.

Thanks guys for the information,  it is clear now,  I'm reading about this right now, but i can't figure out when I should use High-complexity codec or Medium.complexity codec if I have 8 FXO ports. This selection can affect the conferences that I made?



Thansk again

Also a PVDM2-8 is half of a dsp. The PVDM2-16 is 1 DSP.

Thanks a lot for the link man, but according with the DSP Calculator, this relationship is correct?

                              1 PVDM2-8 (1 DSP) has 8 voice channel to g711.
                              1 FXS/FXO port needs two voice channel (1 for TX and the other 1 for RX)
                              then
                              1 PVDM2-8 can support 1 VIC2-4FXS

Thanks for your answer
David
