Hi,
You can run the command show voice dsp group all to check the dsp status. It should show UP.

Hi,
you can run the below commands in sequence:
first login in the GW
a. term mon
b. debug isdn q931
c. Now place the call.
d. After u place the call, u will find call has gone through port at bottom like se0/0/3:15 with called and calling number
003980: Feb 8 17:43:15.814: ISDN Se0/0/3:15 Q931: TX -> CONNECT_ACK pd = 8 callref = 0x000C
e. Now run the command show voice dsp detailed which will give output as below with DSP NUM
DSP DSP DSPWARE CURR BOOT PAK TX/RX
TYPE NUM CH CODEC VERSION STATE STATE RST AI VOICEPORT TS ABRT PACK COUNT
====== === == ========= ========== ===== ======= === == ========= == ==== ============
SP2600 001 01 g729r8 36.1.2 busy idle 0 0 0/0/3:15 31 0 7163/7331
f. Now, u can run the command show voice dsp group all also
dsp 1:

Right now I can't proccess calls on this DSP so I'm looking for somthing like :
DSP from slot 1 process calls from voice port 0/0/0 , 0/0/1 .
DSP from slot 2 process calls from voice port 0/1/0 , 0/1/1.
Is it possible ?

On the 44xx series routers/gateways, the DSPs for the interfaces are on the interface card. DSPs on the motherboard are purely for conferences/transcoding.
