What are the system requirements for Cisco Webex Video Platform?
What Webex versions are compatible with Cisco Webex Video Platform?
End of Support for Cisco Webex Scheduler with Google Chrome Extension, Webex Scheduler for Internet Explorer, Webex Integration to IBM Lotus Notes, Skype for Business, and IBM Sametime
We will be officially retiring support for the Cisco Webex Scheduler with Google Chrome Extension, Webex Scheduler for Internet Explorer, Webex Integration to IBM Lotus Notes, Skype for Business, and IBM Sametime on December 31, 2020. They will no longer be available for download from January 1, 2021. Users of Cisco Webex Scheduler with Google Chrome Extension should move to the newer version of Cisco Webex for G Suite add-on.
- Cascading video conferencing bridges, such as Cisco TelePresence Server or Cisco Meeting Server, to Cisco Webex Video Platform meetings is unsupported.
- Cisco has removed support for Transport Layer Security versions 1.0 and 1.1 (TLS 1.0 and 1.1) for all Secure SIP transactions. Cisco Webex Video Platform only supports TLS 1.2.
- For users registered to a Lync or Skype for Business server, Polycom video devices aren't supported.
On or after August 3, 2018 Cisco Webex will only support the following TLS 1.2 Ciphers:
Cipher Suite: TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA384 (0xc024)
Cipher Suite: TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 (0x006b)
Cipher Suite: TLS_DHE_DSS_WITH_AES_256_CBC_SHA256 (0x006a)
Cipher Suite: TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)
Cipher Suite: TLS_RSA_WITH_AES_256_CBC_SHA256 (0x003d)
Cipher Suite: TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (0xc02f)
Cipher Suite: TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA256 (0xc023)
Cipher Suite: TLS_DHE_RSA_WITH_AES_128_CBC_SHA256 (0x0067)
Cipher Suite: TLS_DHE_DSS_WITH_AES_128_CBC_SHA256 (0x0040)
Cipher Suite: TLS_RSA_WITH_AES_128_CBC_SHA256 (0x003c)
Cipher Suite: TLS_RSA_WITH_AES_128_CBC_SHA (0x002f)
Signature Algorithms Not supported:
SSLv3, RC4, Md5withRSA, DH Keysize < 768, EC Keysize < 224.
The hardware and software requirements are as follows:
- Webex Audio (including Cloud Connected Audio)
- Webex VoIP only is also supported with Cisco Webex Video Platform
Contact your Cisco Account Manager for more information about WebEx Audio, and to obtain the latest list of verified Audio Provider partners.
Make sure that the port range for Cisco Expressway-E, Cisco Expressway, or other edge traversal devices and firewalls allows the following:
Inbound media traffic from the Webex cloud over UDP for the RTP port range 36000 – 59999
Inbound signaling traffic from the Webex cloud over TCP for ports 5060 and 5061
Outbound media traffic to the Webex cloud over UDP for the RTP port range 36000 – 59999
Outbound signaling traffic to the Webex cloud over TCP for the ports 5060 – 5070
For the IP address ranges used by the Webex Cloud, by geographic location, see: WBX264 - How Do I Allow Webex Meetings Traffic on My Network?
The amount of network bandwidth required depends on the requirements of each video device to provide the desired video quality plus presentation data.
We recommend at least 1.5 Mbps per screen for an optimal experience. Some video devices can take advantage of higher rates, and the service can accommodate lower rates, depending on the device.

Quality of Service
The egress gateway must support the following DSCP markings:
- Video traffic marked as DSCP AF41 as per RFC 2597
- Audio traffic marked as DSCP EF as per RFC 3246
Call Control and Firewall Traversal
- Cisco Unified Communications Manager
- Cisco Video Communication Server (VCS) or Cisco Expressway version X8.5.3 or newer (older versions are unsupported)
- Other Vendors
Video Conferencing Systems
- An Encryption option key is required on Cisco Telepresence endpoints
- Cisco TelePresence Endpoints (Running CTS software version 1.10.10 or later)
- Cisco Webex Room Devices
- Standards-based SIP video conferencing systems which:
- Support DTMF via RFC 2833
- Utilize a SIP proxy with firewall traversal capabilities
- SIP stand-alone (no proxy) is unsupported
- Standards-based H.323 video conferencing systems which:
- Support Annex-O (URI) dialing, or IP address dialing (on supported Webex sites)
- Support DTMF via H.245 UserInputIndication method "DTMF," or "basicString."
- generalString, iA5String, hookflash, and any other methods are unsupported
- Utilizing one of the following deployment scenarios:
- H.323 gateway with firewall traversal
- H.323 stand-alone with an H.323-aware firewall acting as a gateway
- H.323 stand-alone with port forwarding and the unit's Internet-routable IP address configured on the device (directly or via the device's NAT-awareness settings)
- Soft-clients such as Cisco Jabber, Skype for Business (Lync) 2010 / 2013
Webex Meetings Clients
- Cisco Webex Desktop clients
- Cisco Webex Mobile clients - iPhone / iPad only, iOS 6, 7 and 8 only
Webex Meetings Video Conferencing is included in Webex Meetings. To check if Cisco Webex Video Platform is enabled for your Webex site, Contact Your Webex Site Administrator.
