Partner Solution Guide – DeltapathOverviewSingle platform, seamlessly integrating and unifying allPolycom video endpoints and infrastructurePolycom customers who have invested into room based videoconference systems are often challengedby a need to make videoconference available beyond the conference rooms. While room based VCsystems gives all the bells and whistles for executives to enjoy life-like high definition videoconference, itlimits the executives to have to be physically present at the conference room. This can be challenging asa lot of videoconference calls may be at awkward times due to time zone differences, the executives maybe traveling, the conference room may be booked for another conference, and having to schedule for theroom and IT support resources discourage ad-hoc discussions.Executives nowadays expect high quality videoconference at anytime, without advance scheduling, fromanywhere, using any device.Solution Overview Deltapath Video Mobility Controller (VMC) is an all-in-one device that is built to enable mobilevideoconference and bridging the typical isolated corporate video islands to the outside world whileoffering security.Deltapath VMC integrates and unifies all Polycom video devices, routes users to conference room fromthe remote location, authenticate and authorize users for services, implement call-routing policies, andseamlessly provide features to all Polycom users anytime, anywhere, on any device.Drive up videoconference usage by allowing employees to dial into conference room or conferencebridges while they are at home or on the go.

It has been a luxuryitem that is usually made available to executives only and requires IT support to pre-test and support thecall. Nowadays, with the wide adoption of Bring Your Own Device (BYOD), availability of high speed4G/LTE and Wi-Fi networks, and accessibility to video enabled devices such as smartphones, tablets,Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform7

Partner Solution Guide – Deltapathand laptops, there is a huge demand for hosting / joining videoconference outside the office, from anynetwork, using a device of their choice.Connecting External Parties / Business-to-Business Video ConferencingAs more confidential and highly classified information gets discussed over videoconference, manycorporations put their video endpoints behind the firewall, forming an isolated video island that is onlyaccessible within their corporate network. It is often then becoming a challenge to allow external partiessuch as a customer/partner/supplier to call in from outside the corporate network.For those organizations that choose to put their video infrastructure with direct WAN access, then it posesa problem of privacy and security. Anyone who is aware of your WAN IP will be able to call into yourconference room. Hackers can also use a war dialer to constantly send malicious packets to disrupt yourcurrent call.Handling Callers from Behind NATBesides security concern with opening access from the WAN into corporate, supporting mobilevideoconferencing often means IT need to support users who are connecting from uncontrolled networkssuch as a Wi-Fi hotspot, a cellular data connection, or a home broadband. This often meant that thevideoconference users are behind NAT, sometimes nested-NAT, which is troublesome for videocommunications.Securely Provision All Your Remote DevicesAs telecommuting becomes more popular, IT managers face a need to remotely provision and managevideo endpoints that are outside the corporate network. Once devices are placed into the public field, forexample an employee’s home, then WAN access to your provisioning server will be required. This oftenposes a security risk if the provisioning data are not encrypted because hackers could easily hack intoyour provisioning server and steal account credentials.The SolutionDeltapath and Polycom, together offers a solution that enables mobile videoconference, external partiesjoining in securely in a controlled manner, remotely provision your devices securely, share content andcollaborate, and easily call each other via video by dialing extensions no matter where the participantsare using any smart devices or Polycom hardware endpoints.Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform8

Partner Solution Guide – DeltapathFigure 1 – A network diagram illustrating Polycom endpoints and servers connecting together via Deltapath VMC.In the above-illustrated example, the Deltapath VMC acts as a firewall bridging the private video LAN withthe public Internet. All devices outside of the corporate network connecting to the Internet behind NATwill be able to register to the Deltapath VMC box. Enterprise B devices will be able to call to Enterprise Aby dialing a one-time secure access code in the form of 123456789@sip.company.com without anyregistration via SIP.Solution HighlightsOne-Time Guest AccessOffer secured business-to-business calling without exposing your video endpoints to the public WAN.Create one-time disposable meeting access code for external parties to call in via SIP URL (e.g.123456789@sip.company.com) from any SIP based video endpoints. The system will automaticallyvalidate the code and ensure the caller is calling at the permitted scheduled time. If the caller calls withinthe scheduled period or as early as 5 minutes before the scheduled time, the system will grant permissionand route the caller to the predefined video endpoint or videoconference room on the RMX. Once outsideof the scheduled time period, the code is no longer valid. This mechanism prevents uninvited guests fromcalling in, callers randomly dialing into your video endpoints or videoconference rooms, or guests callingin at a time not desired by the conference host. Since the calling party does not require any SIPregistration, it also becomes very intuitive and should not require any need for IT to make changes toendpoints or firewall rules.Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform9

Partner Solution Guide – DeltapathDial by Extension or Room NumberTraditionally, Polycom videoconference users would have to dial by IP address to connect to each other.While this is intuitive for a user with IT knowledge, it may pose as a challenge for an ordinary user.Through Deltapath VMC, Polycom endpoints may register to Deltapath VMC as an extension. Thisenables users across the network to dial by extension without knowing the endpoint’s IP address.Understanding that users may want to keep the traditional dialing method while offering this newextension-to-extension dialing, Polycom offers dual stack support for H.323 and SIP. Users who arecomfortable with the tradition H.323 dial by IP address may continue to use H.323, while users who preferdialing by extension can do so and the endpoint will automatically use SIP to complete the call.When Deltapath VMC is interconnected to Polycom RealPresence Collaboration Server (RMX), users willbe able to dial by conference room number to enter into the desired RMX conference room.Video MobilityVideoconference’s biggest enemy is Network Address Translation (NAT). Organizations and homesoften use NAT to share its Internet connection. To overcome the problems associated with NAT,Deltapath VMC has a built-in session border controller; Deltapath VMC performs NAT traversal functionsso that remote users do not need to do any port forwarding on its firewall and will seamlessly be able tomake and receive video calls.Deltapath VMC is able to support typical home and office NAT, including nested-NAT scenarios. SIPALG support on firewall is not required.Universal CollaborationEnjoy true video collaboration by seeing content shared by colleagues in the office or push contentdirectly from your laptop or tablet using Polycom RealPresence Desktop and Polycom RealPresenceMobile respectively. Deltapath VMC supports H.239 that can stream data content and video at the sametime to supported endpoints. Polycom RealPresence Mobile on tablets can also perform whiteboardannotations while sharing data from the tablet. Deltapath VMC also supports H.224 Far-end CameraControl so that supported Polycom endpoints such as Polycom HDX series, Polycom Group series,Polycom RealPresence Mobile tablet edition, and Polycom RealPresence Desktop may tilt, pan, andzoom the far-end camera, allowing the mobile participant to see better on his/her limited-size screenwithout disrupting the participants at the conference room.Secure ProvisioningTo safe guard sensitive account provisioning data, Deltapath VMC supports encryption on all supportedPolycom endpoint’s provisioning data. Devices in the field will be able to download provisioning data inencrypted format over WAN. In the rare event that hackers eavesdrop the communication between thedevice and the server or even gained access into the provisioning server, account credentials are stillsecured.Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform10

Partner Solution Guide – DeltapathSafe Guard Against Threat On The Public InternetTo address the concerns of enabling a WAN access point on your video network, Deltapath VMC has abuilt-in firewall that automatically filters malicious packets. Packets are never forwarded from WAN tointernal directly. Instead, only approved packets such as RTP video and audio can be relayed to otherendpoints in the network. The internal endpoints will only be able to connect to Deltapath VMC to retrievethe approved packets. Any packets that the internal endpoints want to send to an endpoint in the publicInternet will only be sent to Deltapath VMC for further relay to the endpoint on the public Internet. Thetopology of your network is then masked and protected from external parties.In addition, the built-in SIP Application firewall will inspect and monitor all SIP dialogue exchangesbetween the public Internet and the Deltapath VMC server. Attacks such as brutal force attempts,number guessing, or application layer denial-of-service attacks will be quickly filtered by the applicationfirewall.Figure 2 – A functional diagram illustrating how users can access make/receive video calls and call intovideoconference rooms via Deltapath VMC.Deltapath Video Mobility Controller ImplementationDesign ConsiderationsTypically Deltapath VMC sits as a firewall with one interface facing the WAN while another facing internalLAN. It is however possible to let Deltapath VMC sit entirely inside your LAN and simply port forward aWAN IP with one-to-one NAT mapping to the internal IP of the Deltapath VMC box.Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform11

Partner Solution Guide – DeltapathTypical ConfigurationFigure 3 – A network diagram illustrating a typical setup of Deltapath VMC acting as a firewall with one interfaceconnecting directly to WAN while another with an internal LAN IP.In this typical configuration mode, the network topology is relatively simple. Deltapath VMC will act as afirewall and prevent unauthorized packets reaching any of the endpoints sitting in the internal LAN.Alternative ConfigurationFigure 4 – A network diagram illustrating an alternative setup of Deltapath VMC placed on the DMZ behind acorporate firewall that manages the WAN.In this alternative setup, the network configuration is slightly more complex but may be required in certainorganizations due to IT security policies.Deltapath Video Mobility Controller with Polycom Video Endpoints & RealPresence Platform12
