Videoconfrence : Help with MCU to configure in CCM

I have a confusion with the configuration of the MCU in CallManager when i want to have a multipoint videoconference where 3 SCCP viedo endpoints(7985) and 1 Polycom video endpoint (H.323) participate all in the same confenrence!

Here is attached the architecture of my videoconference deseign.

I have activated SCCP and H.323 on the MCU.

I have added the MCU as a conference bridge in CCM, and configured MRGL to use this Conference Bridge.i associated the MRGL with the 3 video SCCP endpoint(7985) and now i can do Multipoint videoconference between the three video endpoints (7985)!!

The problem that i want to the Polycom participate and to initiate a videoconference with the other SCCP endpoints.

I have added a gatekeeper, i registered the MCU (H.323 activated) with the gatekeeper!! In CCM i added the gatekeeper and added a trunk Gatekeeper controlled!!

Now here is my problem: what else to do in CCM??

Should i create a route pattern that points to the trunk ??

or should i add the MCU as a H.323 gateway and a route pattern that points to the this H.323 gateway???

PLz help me, i really have a serious problem.

Yes u'r right, now i'm working all with video conferences in h.323.

I can call the mcu from all endpoints to have scheduled conference. that's ok now.

But the problem i can't make aadhoc conference by : n°conf**calledNumber_1**calledNumber_2

the problem is in hte route pattern in CCM.

I need to estabish videoconferencing beetween endpoint, which are equipaded with the Cisco IP Thelephony 7960 with the video capacities enabled and Cisco Unified Video Advantage software and Cisco VT Camera II. The version of the Call Manager is the version 5 and the MCU is Cisco IP/VC 3510. I added the MCU 3510 as Conference Bridge in the Call Manager, I created a Media Resource Group List with the 3510 Conference Bridge, the phones 7960 are configured with this Media Resource Group List. But my problems is How configure the MCU 3510 ? and my doubt is, How start a videoconferncing?. I need to add a new Route Pattern??

haouaswajih do you have pictures or screenshot of you configuration, Can you send them to me at my mail?

i think that the most difficult part is done now.

plz can u tell me first of all if the bridge is registered with the callmanager?in the administration page of the CCM, click SERVICE >> MEDIA RESOURCE >> CONFERENCE BRIDGE.

Then u have to find your bridge configured (u should see it's IP address).

If this is done, so u need to configure a service (SCCP activated)in the MCU.

U need to login to ur mcu with a browser, then click SERVICES >> ADD , and u need to activate the SCCP field, then choose ur video and audio parameters.

If this is done so to start a videoconference(between 3 persons for example) all u have to do is :

If u have 3 persons : A,B and C (and u'r the person A)

so A calls B normally, here a point to point videocall should be established (done by the CCM), then to make multipoint videoconference, u shoud click on the button MORE of ur phone, u'll see the word CONF, click CONF, u enter the number of the third person and when he hangs on the phone u click an other once on CONF. then a Multipoint videoconference should be established using the bridge this once.

unfortunately i can't have picture of my configuration because i did it in a production in another entreprise but u the online course (ICRMC) an e-learning course, had helped me a lot an there is flash videos that can give u an idea:

i hope this helps,

If there is an other problem plz contact me.

OK, i did it on the MCU 3515 but i suppose it's the same way!!

U go to the Administration page of the MCU, then u go to Protocols, and u should see SCCP, activate this field, and u should allocate a number of port to work with SCCP (in the MCU 3515 max port are 24 or 12 it depends on the model)

Then u should configure a service (SCCP activated as i said before).

Hope this could help u,

Contact me if there is other issues u want to know about.

The configuration of the MCU 3515 and the MCU 3510 are very Different !!!!

I add, the 3510 to conference bridge.

New Media Resource Group, the only resource selected is the VideoConferenceBridge

In the Media Resource Group List, I selected the Media Resource Group Previously configured.

In the Cisco IP Phone in the Medeia Resource Group List I selected the Media Resource Group List Previously configured.

I have three users A (7940 with Video capacities enabled, connect to a PC with VT Advantaje II), User B (7970 with Video capacities enabled, connect to a PC with VT Advantaje II), and User C (CIPC, Cisco IP Communicator, with VT Advantaje II).

When the A call to B or C, the video call is sucessfull, but When I press the button conference, the video call is down :(.

What could be affecting?

your explanation is clear.

i think that the configuration in the callmanager is successfull and there is nothing else to do. But i'm not sure that the config in the MCU is done correcctly!!

1-First of all check the IP address given to the MCU and EMP cards.

2-Check that the bridge is registered with the callmanager with succes. (when it's done with success u can see the IP address configured for the MCU in the administration page of CCM (go SERVICE >> MEDIA RESOURECE >> CONFERENCE BRIDGE, if the mcu is correctly configured and registered with the ccm us should see the ip address of the mcu else u'll see the word "Unknown" )

3-Make sure that u have configured an SCCP service in the MCU it's important!!

u should login into ur bridge via the browser then go to services and add an SCCP activated service (it's madatory to use the bridge as sccp resource)

Hope this could help.

If u have other questions plz ask.

tell me if it works.

haouaswajih ,

Thanks for you answers and help.

I believe than my problem is the MCU, the model of the MCU is the number 3510, and there is not a section to configure the SCCP service o protocol.

Or this specific model is not compatible to operate than conference bridge in the Call manager 5?

other question, if you don't configure the SCCP service, the MCU will not be registered in the call manager, really?

to enable the mcu to register to the CMM u should activate SCCP protocol in the section "Protocols".if u do this the mcu should register with the CCM.

Then to make sure that the endpoints will use the bridge (in sccp) u should configure a service sccp enabled.

Can u acces to the mcu via the browser?

I created a procedure for the integration of the MCU to Call Manager. If you find an error in the procedure or have any suggestions, I will await your response, thanks.

1. Media Resource / Conference Bridge

2. Add New / Conference Bridge Type select Cisco Vido Conference Bridge 35XX

3. Enter the Mac Address, Device Pool, Location, Save

4. Media Resource / Media Resource Group

5. Add New set Name for the Media Resource Group, Select the media resource, ANN, MOH, MTP, and the VCB, SAVE

6. Media Resource / Media Resource Group Lists

7. Add New, set the name select the media resource groups and SAVE

8. DEVICE / Phone

9. Select the phone, in the phone configuration select the Media Resource List created in the above steps. Media Resource Group List of telephonet, reset the phone.


1. Open browser with the address: http://ipaddressmcu/admin

2. In the MCU (browser) click, in Protocols / SCCP

3. In the SCCP page, enable SSCP protocol

4. Add a new TFTP Server, with the address of the CallManager and Port number 69, click in OK

That's is all ????

I need to create a new gateway h.323 in the CallManager?

I need to create a new route pattern in the CallManager?

I think that u did the right steps, just make sure that u added the mcu in the medi resource group.

In the MCU : make sure u have a service SCCP enabled. if not u have to create one and configure its video and audio paarameters.

To respond to ur questions:

If u plan to use the mcu in sccp mode, then u do not have to add the mcu as h.323 gateway in the CallManager. And u do not need to add a route pattern in the CallManager.

In fact all u have to do is to make the phone use the Media Resource Group list that u have created.

To make conference u have two choices : adhoc and scheduled.

In ur case (u are planning to use the mcu in SCCP mode), if u want to make adhoc conference between 3 or more phones u have to do these steps (let's suppose u have 3 phones A,B and C)

-A calls B normally

-A presses the button "more" then "conf" then compose the number of C, when C pick up the phone, A presses "conf" once again.

if u plan to make scheduled confernece,all u have to do is to make a meet me number (in ccm) then all participants call the meetme number and the conference is established (of course the phones should use the Media Resource Group List that contains the MRG that contains the mcu)

Hop this helps u, plz rate it if it does.

if u have any other questions pkz ask.

Good luck

Hi haouaswajih, a have a question? ... I have a video conference with 4 endpoints, and the active speaker I would like that this speaker was shown in full windows? I can do it ?

Honestly id din't do this before, I can't test it, cuz i don't have the mcu 3515 here, i have installed it at a client!

But i have an idea that it should work !! u have to make max layout = 1, and active voice activated Detection, with this only the speaker will take the full screen, the disadvantage of this idea is that u cant see all participant in the conference,

I have an other idea : u should choose the right layout to the conference in a way that u have a central screen in the middle for example, and other small screen around !, u have to activate the VAD (voice activated Detection) and by this way , u'll see that the speeker will take the middle screen,(the big one) i tested it and it worked,

Good luck !

tell me if there is any other explanation u want me to tell.

hi haouaswajih, i have a 3515 and cant find where you setup the VAD at. can you tell me where to find this in the web interface. thx

Hi mikejsims,

Honestly i don't have the mcu now here to see the point with the web interface of the mcu, but as far as i remember the VAD is configured in the mcu 3515 with the web interface when personalizing the service.

So u should open the web admin interface, then go to services, double click on the service that u use, then click on advanced Audio settings , u sould find the option there, and u should also find the minimal durattion of time to talk so that the layout chnage to the speaker.

Plz rate this if it helps.

Good luck, and if u have other questions don't hesitate.

I though that the 3515 only support either sccp or H323 not both. The H323 device can not start or invite a SCCP conference,the larger MCU can do both -SCCP H323

This is great information, however, I have a rather odd question. I have CCM 4.2.3 a 3515 MCU as well as Cisco Meetingplace. The Cisco 3515 was purchased solely for use with Video enabled calls both from actual video endpoints, IE, polycom, as well as to be used with existing VTA phones. All is well in this are, VTA enabled phones can simple conference in other VTA users, or endpoints and all is happy, a happy Multi-point call. So my issue, I only have a 24 port MCU, when people have been using MeetMe within call manager that do NOT have VTA, its still invoking the MCU and using resources that would better be handled but CCM or meetingplace if possible since we have 120 ports on that device...

Any ideas or suggestion, I know I can mess with the MRG but I dont want to block conferences, and MeetMe calls that have Video, from using the MCU, I only want to block Audio Only calls from using the MCU resources..

Hi.. i am wondering if you have solved the problem regarding the h323 endpoints.. i have been tracking down the messages but i cant seem to find it. thanks. I really need the solution. I am using tandberg mxp550 and polycom vsx3000. thanks so much... ;)

User Badges:

Hi, as i undestood, you have a cisco MCU, Tandberg vsx3000 and a Polycom.

So you need to use the mcu is H323 Mode and register it with a gatekeeper.

You have to register the polycom and Tandberg to the gatekeeper too.

Then you can have videoconferneces.

If you have any other questions please don't hesitate.

Sorry to jump in there. I thought that a MCU can either be H323, sip OR sccp but not both as I understand that a H323 cannot invoke a conference when in SCCP mode though can be invited to join or dial in as part of MeetMe when in H323 mode. If this is correct and we use Gatekeeper so how does a SCCP mode MCU register to a Gatekeeper if you need it in H323 mode
