Short DSPs due to Router calculating DSPs for T1 (MPLS)

I have a 2851 router. I am trying to set conferencing to use the local router resources and not the ccm server. It has PVDM2-48. In the router is: 2- vwic-1mft-T1 (1 pri and 1 MPLS T1) 1- FXS/DID 8port 1-FXO 6port. This is a SRST router with most calls going out local PRI's. When I try to set the- 2851 (config)# dspfarm profile 2 conference

!

Maximum sessions 2

it will only allow 0 for max.

Is there a way to share the dsp's between T1 and conference sessions instead of the router automatically using 24 for the T1?

You can not share a DSP between voice termination ports and conference bridges. PVDM2-48 has 3 DSPs and you'll need all 3 to support 23+8+6=37 ports using G.729. If you decide you use G.729 for example for tail end hop off you may not have sufficient PVDMS for that.

Your only option is to add more PVDMs at this time in order ro support hardware conference bridges.

HTH,

Chris
