Configuring Conferencing and Transcoding

[pkluss]

<moved from the General section>

I'm attempting to configure transcoding and conferencing on my Cisco 2811. We're running CME and CUE. I did not setup this router initially, so there are gaps of knowledge about my own config. I know that we have conferencing setup, but I cannot figure out how to run transcoding along side of it. Here are the lines from my config that I believe are pertinent.

!

voice-card 0

dspfarm

dsp services dspfarm

!

sccp local FastEthernet0/0

sccp ccm 192.168.100.253 identifier 1

sccp

!

sccp ccm group 1

associate ccm 1 priority 1

associate profile 1 register mtp001cf6806720

keepalive retries 5

switchover method immediate

switchback method immediate

switchback interval 5

!

dspfarm profile 2 transcode

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 8

associate application SCCP

!

dspfarm profile 1 conference

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

codec g729r8

codec g729br8

maximum sessions 4

associate application SCCP

some results from a 'show diag' are below:

Slot 0:

C2811 Motherboard with 2FE and integrated VPN Port adapter, 2 ports

PVDM Slot 0:

16-channel (G.711) Voice/Fax PVDMII DSP SIMM PVDM daughter card

PVDM Slot 1:

48-channel (G.711) Voice/Fax PVDMII DSP SIMM PVDM daughter card

WIC Slot 2:

2nd generation - FXO Voice daughter card (4 port)

WIC Slot 2:

2nd generation - FXO Voice daughter card (4 port)

WIC Slot 3:

FXS Voice daughter card (4 port)

I've looked at all of the documentation for this subject, and I'm not sure I've found the case that applies to my hardware setup.

Thanks for the assistance.

The DSP farm support a combination of transcoding sessions, MTP sessions, and conferences simultaneously. The DSP farm maintains the DSP resource details locally. Cisco Unified Communications Manager requests conferencing or transcoding services from the gateway, which either grants or denies these requests, depending on resource availability.

If this is going to be for CME use the config should look something like this

sccp ccm group 1

bind interface Loopback0

associate ccm 1 priority 1

associate profile 1 register conf

associate profile 2 register trans

keepalive retries 5

!

dspfarm profile 2 transcode

codec g711ulaw

maximum sessions 5

associate application SCCP

!

dspfarm profile 1 conference

codec g711ulaw

maximum sessions 2

associate application SCCP

telephony-service

sdspfarm units 2

sdspfarm transcode sessions 5

sdspfarm tag 1 conf

sdspfarm tag 2 trans

conference hardware

That seemed to be what I needed essentially. Unfortunately I'm getting a 403 error on the configuration guide you linked, but most importantly I am up and running.

Thanks.

Hi Philip,

Here is a link for that doc that you should be able to see;

http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmetrnsc.html

When you see a link like that one that has the word "partner" in the url, just remove that word and re-paste. You and I don't have access to these links in that version :)

Hope this helps!
