Hi,
I have one site configured as cme and rest all the sites are registered in one cucm. Now transcodoing, conferecing & MTP configuration on cme router would be poiting to cucm or would remain for only local phones in cme.

Hi Omer
You can use resources of your CME to register for your CUCM and when your SRST start to work , your resources can be used on SRST. Please find the below:-
sccp local Loopback105
sccp ccm 10.50.X.X (cucm ip) identifier 1 version 7.0
sccp ccm 10.50.X.X (cucm ip) identifier 2 version 7.0
sccp ccm 10.1.184.65 255.255.255.0 identifier 3 version 7
sccp
sccp ccm group 1
associate ccm 1 priority 1
associate ccm 2 priority 2
assocuate ccm 3 prio 3
switback method immediate
switchover method immediate
swithback interval 3
telephony-service
sdspfarm units 3
sdspfarm transcode sessions 4
sdspfarm tag 1 abc_CONF
sdspfarm tag 2 abc_XCODE
sdspfarm tag 3 abc_MTP
As you see on my configuration , i set priortiy for your CUCM than CME. When the link is ok between your CUCM and CME , all resources will be ok for your CUCM. During SRST , the resources will be register for your CME.
Thank you

Hi.
If you have defined CME conference bridge and mtp resources as Hardware conference bridge and MTP on CUCM and you have associated them to a MRG MRGL and Device Pool, these resources can be also used by CUCM registered ip phones.

Hi
Based on your configuration , these resources will point to your CUCM only.
1-You can make the resources of your CME is only serve registered Phones on CME. with the same configuratio as you do above , with some modifications, as below;-
sccp local Loopback105
sccp ccm 10.1.184.65 255.255.255.0 identifier 1 version 7
sccp
sccp ccm group 1
associate ccm 1 prio 1
telephony-service
sdspfarm units 3
sdspfarm transcode sessions 4
sdspfarm tag 1 abc_CONF
sdspfarm tag 2 abc_XCODE
sdspfarm tag 3 abc_MTP
2- If you use the resources of CME to CUCM , just register Transcode ,MTP and conference bridge to your CUCM .Create MRG and MRGL and assign MRGL to device pools.

Hi omerpal,
Where to register DSP resources depends on the requirement.
If a site is CME and CUCM is connected Via WAN, DSP resources should register to CME.
Just assume what will happen if WAN fails. These resources will get unusable.
If you are Using MTP for fast start/ early offer calls from CUCM. You should register this MTP with CUCM.
Conferencing will not work during WAN failure if Conf. bridge is registered to CUCM.
Register these resources to CME using ommands suggested by islam.

+5 to Carlo, Islam and Aman..Excellent answers to both. I just want to add to their ideas. Currently your ccme phones will not be able to use the media resources registered to CUCM. Your cucm registered phones can and will use the media resources that you have configured on ccme and registered to cucm. You will need to configure media resources for ccme registered phones as shown by Islam

Thanks all for your replies.
For cme-cucm , it's agreed to configure media resources in cme. But in h323 gateways where srst is configured what could be configuration. I mean to say media resources shall be configured in cucm or cme.
10-25-2013 04:34 AM
On your srst gateway you only have one option, whic is to configure media resources to register to cucm. You cant use media resources outside of the ccme gateway itself. It has to b e co resident with ccme.

In a nutshell, We need Media Resources in both ways.
I can understand that in cucm scenario, transcoding can be used to convert G.711 into G.729 since CUCM will be across the wan link.
In CUCME, do we still need transcoding? I need to understand MTP requirement in CUCME too
Thanks

Hi
1- If you need to use transcoding to convert between Codecs, so you will still need that during SRST.Based on that you will still use the resources on the both CUCM or CUCME
2- Look Transcoder is as MTP but needs hardware resources from your routers.
The best scinario to regiter all resources for your 2 X CUCM as high priority , and during SRST it will register to your CUCME. Please find above my configuration for this scinario,
Thank you

Hi
Let me share with you some details :-
1- you have transcoder , to transcode between codecs .
2- conference for (ad hoc or meetme).
3-MTP ( For RSVP) , if you need to guarantee bandwidth between sites.
1- Based on your configuration , all of above required resouced from your router.Based on that we will register all of above to your Pub and Sub on your gateway.
2-Quesyion here , you will enable SRST?. If you enable SRST without registering these resource to your SRST IP or CME IP , the phones will resgiter but without (transcoding, confernce , MTP) , so you have to register these resources to your CUCME , so all will work as same on CUCM up or SRST up.

Hi
Some defines for media resources , to know which will be used for you:-
Media Termination Point
•Define Supplementary Services.
•Used when SCCP communicate to SIP Devices
•H323 v1 communicate with v2.
Music On Hold
•Provide music when call is on hold
Conference
•Provide resources when party initiate a conference sessions
Transcoding
•Converts codec from G.711 &G.729
