What do I need to connect OCS 2007 R2 to external sip clients (and possibly h.323 clients) using IP and SIP names

Question
-
Hello
This is giving me a real headache so please could someone help me.
We currently have an OCS 2007 r2 setup which is working fine with a standard server backend and an edge server (required due to the firewalls between central and schools). We are now looking at connecting this to external clients. We are not talking telephone or voip stuff we just want to Video Conference with SIP (and possibly h.323) clients on the web via IP mostly and sip names (I believe these are ian@someone.com type names). All the guides I keep reading talk about linking to pbx's and pstn networks and I just cant get my head round it.
We have a codian 3500 gateway but have been told we need to replace this with a tandberg Video Communcaitons server due to the fact we are using R2, I do not understand why but the cost of the VCS box may leed us to going open source (or looking for cheaper options) so I need to get my head round what we need. For example do we need a mediation server and is there away of getting ocs 2007 R2 to working with our codian 3500 gateway. So the requirements wee need are.
1) for a school to load office communcaitor and put either an ip or name in that will connect them via sip (may require h.323 but would be happy to get sip working) to the external sip/h.323 client whatever that may be.
2) External Clients can enter name@domain.com (we have the dns already up and running for sip) and conenct to an office communcaitor client in the school.
Can anyone help me with what I need to do to get this working with either the codian gateway or and open source gateway.
thanks in advance you would really help me out.
cheers

Take a look at SmartSIP which is a product that can allow registration of industry standard SIP devices with OCS.

The easiest way to do this will be the smartsip solution, i've heard great things about it.
If you have existing Tandberg or Polycom video conferencing deployments you can integrate with those as well using Tandberg or Polycom gateways specific to their video devices, would need more details to get you a direct model.
However the smartsip solution covers pretty much everything, and evangalyze should be able to get what you need working with no issues.

Currently SmartSIP is for voice clients only - we do not support video clients. The primary use of the product is to take existing SIP phones (either desk phones or softphones) and connect them as OCS voice endpoints. The actual discovery/provisioning/configuration can be done either by manually configuring the endpoint to connect to OCS or by using the appropriate DHCP option for automatic configuration (preferred).

Ian,
If I understand you correctly, all you really want to do is use Video conferencing. The part I am unclear on is whether the schools are connected via MPLS, VPN or will be coming from the internet? Please let me know.
As far as the clients connecting to OCS, they will all need sign in names, IPs will not work for this. You shouldn't need any third party equipment if all users are going to be connecting via OCS, OCS itself will act as the standalone conferencing unit. You also will not need a mediation server as you are not connecting OCS to the PSTN or a PBX, and that is what the mediation server does.
Hope this helps.

Thanks for your reply.
The schools are all connected via a WAN to the central network which hosts the OCS. They are all working no problems, they can VC IM all the stuff you can do with OCS. The problem is connecting them to external Non OCS SIP clients. How do I configure it so that someone using a non ocs sip client on the interent can call a user in the school and vicaversa.
Hope this makes it a bit clearer.

Ian,
I do understand your question now, sorry I misread the thread title. I'm not entirely sure if that is possible and what methods would be required to make that work. I believe natively there isn't anything in OCS that will allow that to happen. Hopefully someone else can chime in. Sorry I couldn't help.

Thanks for that, it looks like what I could need.
If I install SmartSIP with my OCS will I be able to load a Office Communicator client enter an IP address of a sip endpoint and connect and do a full video conference?
cheers

hi
Sorry about i am not expert in the SMARTSIP solution.
I think you could turn to the vender of the product.

We are looking at supporting video in the future and have made some limited progress in the lab. The main limitation is codec support on the endpoints - a MOC endpoint has only h323 whereas common video endpoints use h263. This means that we can have h263 video endpoints register with SmartSIP and make and receive video calls from other h263 endpoints but not directly with a MOC client. We are also looking into using the Tandberg MCU for doing the video transcoding.
We are thinking about opening up a beta program for the video stuff, but its currently very early days - contact Mike or I if you are interested.

Thanks for everyones replies, we are trialing a Tandberg VCS box and will go from there.
