In the headquarter i have CCM 4.0(2).
In a branch office i have a router 2811, 1 PVDM2-16, Unity Express (Service Module) and 4 FXO (VIC2-4FXO) ports.
How I can calculate the exact number of DSP resources for intall 4 FXO (VIC2-4FXO) aditional ports?

You can use the dsp calculator. each fxo should occupy 1 dsp slot. You should have 12 left for conferencing or transcoding purposes.

If you are only going to need PVDMs for voice channels then you need 1 PVDM channel per G.711 call, so PVDM2-16 will allow for 16 calls. With G.729 it takes 2 channels per call for a totoal of 8 calls.

No you don't need more PVDMs for Unity Express, unless you will need to transcode calls from g729 to g711 as that is the only codec CUE supports.

This site is a branch office.
Some times it establishes calls between this site and the headquarters or to others branches,
Will I need more PVDM resources??? and What about HW MTP?
Very Thanks
