C40 Telepresence

[briansciarra]

I have a customer that has one one Cisco C40 Telepresence appliance. 

They want to begin using this for video-conferencing.

There are no other appliances, they want to use Jabber to conference into the C40.

Is this possible?

[Dennis Mink]

Yes this is possible, Is the C40 registered on CUCM, TCS, gatekeeper?

Tell me what else you have in your network re. collaboration

[briansciarra]

No its not registered to CUCM yet.

There's really nothing else, they have the one unit and they want to jabber into it.

But they haven't bought Jabber licenses yet.

So I think that's it, just register CUCM as the gatekeeper, buy jabber licenses, and NAT the telepresence for outbound dialing, and open ports for H323 and SIP - sound about right?

[briansciarra]

The reason I ask is because some salesman told my customer they could just throw the C40 on the DMZ and start video-conferencing by webbing to the IP of the device.

You can set the C40 up to do point to point conferences, like dial based on IP address. 

If you set it up a as a pure H323 endpoint, it will not be part of any dial plan so you will always need to "dial" IP addresses, private or public.

C40 in a DMZ, well, maybe the salesman should stick at what he is good at.  It could be impractical/impossible to stick the C40 in a DMZ. But what he is getting at is hiding the C40 behind a public IP address to 3rd parties can dial into it.

You could set up the C40 in a DMZ, essentially deploying it as a standalone endpoint not registered to a call control server.  However, if you have CUCM it's better to leverage it, makes calling that much easier, plus it's more secure.

You should register the C40 to CUCM, see Administering Endpoints Running TC7.2 n UCM 10.5.1 the for more details.  Once you do that, Jabber clients can dial into the C40, but if the C40 doesn't have a multisite license, you can only connect 2 Jabber client's at a time, one with video/audio and the other with just audio.  If you want to have more than 1 video call with the C40 at a time, you'll need a conference bridge such as an MCU or TelePresence Server.

For external endpoints, you would setup your CUCM with the Expressway solution, they consist of Expressway-Core and Expressway-Edge.  Allowing for secure firewall traversal for external endpoint registration to your CUCM inside the network, as well as inbound/outbound calling.

[briansciarra]

Oh so you CAN put it on a dmz as a stand-alone device.

Would we be able to use Jabber to connect in that scenario?  Another cisco codec?  Possibly FaceTime or some other video meeting app?

[Patrick Sparkman · Accepted solution]

You could, search the TelePresence section of the forums for "standalone", you'll find many posts on how to set it up that way.  However, calling it won't be as simple as you think for a Jabber client registered to CUCM, since CUCM doesn't support IP dialing, though it is possible with a workaround.

You can only call standards based video conference endpoints.  Meeting clients such as Facetime, Skype, GoToMetting won't work.

Note: Your question would be better off in the TelePresence section of the forums, where these devices are more actively discussed and people can help get you the answers you need.  You can move your question to the correct section by editing it and changing the categories at the bottom.
