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 ... View more

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        CME#sh dspfarm profile 1 Dspfarm Profile Configuration Profile ID = 1, Service = CONFERENCING, Resource ID = 1 Profile Description : Profile Service Mode : Non Secure Profile Admin State : DOWN Profile Operation State : DOWN Application : SCCP   Status : NOT ASSOCIATED Resource Provider : FLEX_DSPRM   Status : NONE Number of Resource Configured : 2 Number of Resource Available : 0 Maximum conference participants : 8 Codec Configuration: num_of_codecs:6 Codec : g711ulaw, Maximum Packetization Period : 30 , Transcoder: Not Required Codec : g711alaw, Maximum Packetization Period : 30 , Transcoder: Not Required Codec : g729ar8, Maximum Packetization Period : 60 , Transcoder: Not Required Codec : g729abr8, Maximum Packetization Period : 60 , Transcoder: Not Required Codec : g729r8, Maximum Packetization Period : 60 , Transcoder: Not Required Codec : g729br8, Maximum Packetization Period : 60 , Transcoder: Not Required        CME#sh voice dsp group all DSP groups on slot 0: DSP groups on slot 1: dsp 1:   State: UP, firmware: 28.3.5   Max signal/voice channel: 16/16   Max credits: 240   num_of_sig_chnls_allocated: 0   Transcoding channels allocated: 0   Group: FLEX_GROUP_VOICE, complexity: FLEX     Shared credits: 240, reserved credits: 0     Signaling channels allocated: 0     Voice channels allocated: 0     Credits used (rounded-up): 0   0 DSP resource allocation failure ...
