[cisco-voip] using my DSPs on a 3845

[Lelio Fulgenzi]

I've got a 3845 with a PVDM2-64 as far as I can tell. Well, that's what I ordered and I trust Cisco! A "show voice dsp" shows the following:
  DSP   DSP              DSPWARE CURR  BOOT                         PAK   TX/RX
  TYPE  NUM CH CODEC     VERSION STATE STATE   RST AI VOICEPORT TS ABRT PACK COUNT
  ===== === == ========= ======= ===== ======= === == ========= == ==== ============

  C5510 001 02 g711ulaw    9.2.2 busy  idle      0  0 0/1/0:23  22    0  63104/64754

  C5510 001 04 None        9.2.2 idle  idle      0  0                 0          0/0

  C5510 004 15 None        9.2.2 idle  idle      0  0                 0          0/0
  C5510 004 16 None        9.2.2 idle  idle      0  0                 0          0/0
  ------------------------END OF FLEX VOICE CARD 0 ----------------------------
I gather that each DSP can handle 16 voice calls, so if I have two T1s = 23 calls * 2 (each has their own Dchannel)=46 calls / 16 = 2.875.

So that means three DSPs are required to handle my voice calls and I have one left for conferencing.

Do I just create a DSP farm with one DSP and somehow assign it as a conference resource in Call Manager?
