Show diagnostics shows the PVDM is in place. But when I try to configure max sessions for the dspfarm there are none available. This is the only dspfarm profile although another had been previously configured. Why no channels available??

So if I am to assume that you have a voice circuit coming in to the vwic2-1MFT-t1 card, then you are probably maxed out on your dsp resources. They dsp resources are allocated to that card as well as the 4 port FXO and 2 port FXS. Use the DSP calculator, to see how many DSPs you should run with what you have, but note the DSP calculator does not account for DSP resources needed for auxilary items such as conference bridges. I think you need to add another DSP resource in there.

Great stuff Ken. I'll check out the calculator and likely have the local guy remove the FXS module which are not used at all.

I think you are still going to need more DSP resources - if you are using a voice T1 in the MFT card. I ran the calculator on your setup and assumed 24 calls on the MFT, 4 calls on the FXO and 2 calls on the FXS. That needed 2 of the 16 PVDM cards of which you needed one, and remember that doesn't account for extra DSP resources needed for a dspfarm.

you have only 16 and the cards that you have need around 40 so you have to add more DSPs to you router it is better to put one 64.
if you want to test it remove all the cards if the router is not production and check.
