Conferencing fail at Branch site

[ev1205]

We have a CUCM ver 10 platform on a client with one branch office.

On branch office we configured a dspfarm on Cisco 2921 to  enable conferences, as you can see here:

sccp ccm group 1
 associate ccm 1 priority 1
 associate profile 2 register XCODE-Branch
 associate profile 1 register XCONF-Branch
 associate profile 3 register MTPCUBE
!
dspfarm profile 2 transcode  
 description Resources for Transcoding
 codec g729r8
 codec g729br8
 codec g711ulaw
 codec g711alaw
 codec g729ar8
 codec g729abr8
 maximum sessions 12
 associate application SCCP
!
dspfarm profile 1 conference  
 description Resources for Conference
 codec g711ulaw
 codec g711alaw
 codec g729ar8
 codec g729abr8
 codec g729r8
 codec g729br8
 maximum sessions 3
 associate application SCCP
!
dspfarm profile 3 mtp  
 description MTP HW CCM
 codec g711ulaw
 maximum sessions software 35
 associate application SCCP

On my CUCM we have transcoder "XCODE-Branch", conference "XCONF-Branch", and MTP "MTPCUBE" properly REGISTERED.

We have included these resources on Media Resource Group List of this Branch office, and all Ip Phones are using it.

But when we try to establish a conference (with external<-->internals and internal<-->internal calls)  at branch site, the call fail !!!

Do you know what can be missing on my configuration??

When you configured the conference media resources, did you assign the appropriate Device Pool with the correct Region? Also did you reset the media resource? Can you perform an internal conference and verify that the DSP resources are being used at the branch office. Do a "show dspfarm dsp active" on the branch router to verify.

Thanks Yosh !!!

Yes the Media resource is on proper DP /Region.

I did a reset of Conference Media Resource at CUCM, and shut/no-shut of conference profile on router. Later I tested with a PSTN call, and trying to establish a conference with another internal DN.....it failed.

Here you have output of "show dspfarm dsp active" during test

I hope this can help !
