Hi all,

Sorry for this newbie question, but i've been searching for the answer and still can't find it. In the transcoder configuration, there are Cisco IOS Media Termination Point and Cisco Media Termination Point Hardware. Also, In Conference Bridge configuration there are IOS Conference Bridge and Conference Bridge Hardware. Can anyone tell me what is the difference between the two of them?

Thanks,
Sumarto

The difference in both cases is that the IOS version refers to modules, such as the NM-HDV, which are in devices running Cisco IOS. The other hardware resources are non-IOS devices, such as the Catalyst 6608 module.

I would recommend you read through the IP Telephony Solution Reference Design Guide. You can find a lot of good information in it including Media Resources.

Hi Rob,

I've read the IPT SRND before and again. Yes, It does has a lot of information about DSP modules, but i can't find information on how to configure IOS MTP. The module that i'm testing right now is NM-HDV-2T1. When i select MTP Hardware as Transcoder Type and enter the MAC Address, it can register with the call manager. I can verify it on the CCM and the IOS gateway. But the i select IOS MTP, it prompts me for Device name. I tried using IP address and hostname, but i cant't see the registration on both ends. Is there any specific configuration that i have to do on the IOS gateway?

Thanks,
Sumarto

The configuration steps for the IOS device can be found at the following url:

http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080110bc5.html

On the CallManager configuration page use the IP address of the interface you identify in IOS with the "sccp local <interface>" command.

The Voice command reference guides and feature guides for 12.2T IOS are also essential, if somewhat dry, reading.

Hi Rob,

The Transcoder configuration in http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a0080110bc5.html#76100u is for CCM 3.2. In the document i can't see the difference between IOS MTP and MTP Hardware because both are using MAC address.
Here is my observation:
In CCM 3.3, IOS MTP Transcoder will ask for Device name. I put the ip address as defined in IOS "sccp local" command, but it can't register with CCM. When i tried using MTP hardware and put in the MAC address, it was able to register with CCM and obtain the ip address automatically. This verifies that my configuration on the IOS device is correct.
Any suggestion?

Thanks,
Sumarto

My bad, gave you incorrect info.
IOS MTP resource should be added to CallManager using MAC address in format

xxxxxxxxxxxxMTP

where x's = MAC address

you can use show sccp and debug sccp all command in ios to troubleshoot.

The correct format is MTPXXXXXXXXXXXX. Thanks, it's working now. But i still don't get why they need to put 2 types of transcoders on the menu, but there's no difference in configuration.

Actually, in CallManager 3.3 documentation, including the help files installed with CallManager, the format is as I gave. Conflicting/incorrect documentation from Cisco? Say it aint so...

I know, the MTP leads, not trails the mac address. It just that you'd think that they could get the help files on the server right.

Hi All,

The reason for the breakout between std. hardware CFB and transcoder vs. IOS CFB and transcoder under Media Resource config. is that CCM requires a unique device name in SQL. The new IOS resource selection prepends CFB or MTP in front of the MAC so you can register both CFBs and XCoders from the same router to CCM. The previous fields for 6608 and AGM generate the the device name only using the MAC address which is a single value using the DSP Farm feature. Hope thats what you were looking for.
