Hi,
Can Cisco CME to act as the DSP farm host for MTP resource?
I know it's OK for transcode and conference resource. But It's not successful with MTP resource.

I seem to remember that you cannot register an MTP to CME. As you are probably aware, the XCODER is a sort of super MTP, so XCODERS will do the job of an MTP, abeit rather inefficiently.
If you are using CME 3.4 or less, you need "transfer-system full-consult" under your config to do consultative transfers etc.

Do you have some document or release notes that I can support this comment: That I cannot register an MTP to CME, because my client said that He already register a MTP in a CME version 6.x, so I need to sustain that!

Miguel,
-There's no such thing as CME 6.x:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/requirements/guide/33matrix.htm
-Regarding the MTP question, I couldn't find any external documentation, but if you read the CME admin guide:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/admin/configuration/guide/cmeadm.html
-You'll find nothing about MTP configuration on CME, that means is not supported, or in other words, not needed.
-Finally, there is a MTP command that you can use for IP Phones registered to CME:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucme/command/reference/cme_m1ht.html#wp1108535
To send voice packets from an IP phone to the Cisco Unified CME router, use the mtp command in ephone or ephone-template configuration mode. To return to the default, use the no form of this command.
mtp {video-only | both}
no mtp {video-only | both}
Normally, media packets (RTP packets) that are sent between IP phones in the same Cisco Unified CME system go directly to the other phone and do not travel through the Cisco Unified CME router. When these packets are sent from a remote IP phone to another IP phone in the same Cisco Unified CME system, they may be obstructed by a firewall. The mtp command instructs a phone to always send its media packets to the Cisco Unified CME router, which acts as a proxy and forwards the packets to the destination. Firewalls can then be easily configured to pass the RTP packets because the router uses a specified UDP port for media packets. In this way, RTP packets from remote IP phones can be delivered to IP phones on the same system. The default is that this function is off and that RTP packets that are sent from one IP phone to another IP phone in the same Cisco Unified CME system go directly to the other phone.
If you use an ephone template to apply a command to a phone and you also use the same command in ephone configuration mode for the same phone, the value that you set in ephone configuration mode has priority.

on CME 8.6 works.
1) under telephony-service enable auto-reg-ephone
2) under telephony-service increase max-ephones
