Hi,
We have got a 2800 router configured in CCM5.1.2 as an H.323 gateway. There are plenty DSP resources in it so we want to use it as a hardware transcoder. But as soon as we try to create a transcoder in CCM with the gateway's IP address the CCM says: "Error - duplicated line." We can create a Transcoder with any other IP address different from the gateway's. Is there any kind of restriction in CCM that an H.323 gateway can not be used as a Transcoder? Thanks.

Hi, Alexander!
You need to configure transcoder using the part of its MAC address as the name. The whole name will look like MTPaaaabbbbcccc.
You need to configure your dspfarm profile as sccp resource on the GW.
Good luck!

Actually the name can be anything you want it to be as long as the name matches on the CallManager and the GW, such as this:
sccp local GigabitEthernet0/0
sccp ccm x.x.x.x identifier 1 version 5.1
sccp ccm y.y.y.y identifier 2 version 5.1
sccp ccm z.z.z.z identifier 3 version 5.1
sccp
!
sccp ccm group 1
associate ccm 2 priority 1
associate ccm 3 priority 2
associate ccm 1 priority 3
associate profile 1 register NAME_ME
!
dspfarm profile 1 transcode
codec g711ulaw
codec g711alaw
codec g729r8
maximum sessions 16
associate application SCCP
HTH,
Chris

Hi Chris,
We have actually tried this, but could not make the transcoder to register with CCM. That is why we have decided to use the IP address as the name. By the way, in the gateway IOS we use there is no "version 5.1" option for "sccp ccm" command, only "version 5.0". Does it make any difference?
Thanks.

Well, it depends on the version of IOS you have, however what I have found on numerous installs is that using version 4.1 works great even with CM 5.1, if that does not do the job then try it without the version parameter.
Trust me, you can use any name you want there.

OK, we'll give it another try. Thanks a lot for your help.
