DSPFarm 2851 / NM-HD-2V

[dangilley1]

Hi Everyone,

Quick question. I'm trying to set up cbarge on CME 8.6 running on a 2851. I see that I need dsp to accomplish this. Can I use  nm-hd-2v (has 8 dsp?) for dsps for cbarge (and then fxo/fxs? or without vic card?) or must I use a nm-hdv2 with pvdm2s?

Thank you,

Dan

You don't need any NM for DSP on an ISR router. Just install PVDM2-xx directly on the motherboard.

Hi Paolo,

Thanks for the reply. I don't have any PVDM2s but I do have a NM-HD-2V without FXO/FXS that I was hoping to be able to use for cbarge conferences, but I can't seem to get it to work. Is it possible?

Thanks,

Dan

Can you post "sh run"?

Hi Chris,

I reloaded the router after I was unsuccessful just to remove anything I did that may have been erroneous. I followed the post by aokanlawon in the thread below to the letter:

https://supportforums.cisco.com/thread/2011036

The only thing I did additionally was to add the cbarge softkey to the ephone template. I did get the same error in the thread above when dialing the conference # (Can not complete conference), and I tried to remove conference hardware from telephony-service as mentioned in that thread as well.

Thank you,

Dan

Dan,

This gives a major clue as to whats going on:

Application : SCCP   Status : NOT ASSOCIATED

You'll need to create a loopback, then associate the dspfarm profile via SCCP so it registers. You'll need all of the following, with some modifications based upon your config:

sccp local Loopback0

sccp ccm identifier 1 priority 1 version 7.0

sccp

sccp ccm group 1

bind interface Loopback0

associate ccm 1 priority 1

associate profile 1 register CME-CONF

voice-card 1

dspfarm

dsp services dspfarm

dspfarm profile 1 conference 

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 8

associate application SCCP

telephony-service

sdspfarm tag 1 CME-CONF

no privacy

conference hardware

Remember to bring the dspfarm up with no shut.

Best,

David
