[cisco-voip] DSPFARM Question

[steve.siltman at assurant.com]

I need to better understand DSP resource allocation.  Please look at the 
following:

voice-card 0
 no dspfarm
 dsp services dspfarm
!
voice-card 1
 dspfarm
dsp services dspfarm


This is all thats configured on one of our voice gateways.  This voice 
gateway has dial peers configured into CVP/ICM fun stuff.  There are no 
dspfarm profiles, no sccp back to CallManager and no dspfarm max anything. 
 This router does have a few T1 controllers configured.   We recently had 
an error message in the log FLEXDSPRM-5-OUT_OF_RESOURCES.    Operations 
worked with Cisco to fix the issue by doing a no dspfarm/dspfarm and 
cycling the T1 controllers.  The error went away. 

Now with my questions. 

1.  The dspfarm command allows the dsp's on that voice-card to share its 
resources with the routers resource pool?  The no dspfarm command keeps 
those dsp resources for that voice-card only?

2.  What are the dsp's doing on this router if no profiles and sccp isn't 
configured? 
     Issuing any show dspfarm commands always comes back with the same 
result (Total number of DSPFARM DSP channel(s) 0)

3.  Do the T1 controllers use the dsp resources with only the above 
configured?

The 3845 router is running 12.4(7g).  The router is not configured as a 
gateway in CallManager.

Thanks,
