Portreferensinformation för Webex Calling

A correctly configured firewall and proxy are essential for a successful Calling deployment. Webex Calling uses SIP and HTTPS for call signaling and the associated addresses and ports for media, network connection, and gateway connectivity as Webex Calling is a global service.

Not all firewall configurations require ports to be open. However, if you're running inside-to-outside rules, you must open ports for the required protocols to let out services.

Network Address Translation (NAT)

Network Address Translation (NAT) and Port Address Translation (PAT) functionality are applied at the border between two networks to translate address spaces or to prevent the collision of IP address spaces.

Organizations use gateway technologies like firewalls and proxies that provide NAT or PAT services to provide internet access to Webex App applications or Webex devices that are on a private IP address space. These gateways make traffic from internal Apps or Devices to the internet appear to be coming from one or more publicly routable IP addresses.

If deploying NAT, it’s not mandatory to open an inbound port on the firewall.
Validate the NAT pool size required for App or Devices connectivity when multiple app users and devices access Webex Calling & Webex aware services using NAT or PAT. Ensure that adequate public IP addresses are assigned to the NAT pools to prevent port exhaustion. Port exhaustion contributes to internal users and devices being unable to connect to the Webex Calling and Webex Aware services.
Define reasonable binding periods and avoid manipulating SIP on the NAT device.
Configure a minimum NAT timeout to ensure proper operation of devices. Exempel: Cisco phones send a follow-up REGISTER refresh message every 1-2 minutes.
If your network implements NAT or SPI, then set a larger timeout (of at least 30 minutes) for the connections. This timeout allows reliable connectivity while reducing the battery consumption of the users' mobile devices.

SIP Application Layer Gateway

If a router or firewall is SIP Aware, that is the SIP Application Layer Gateway (ALG) or similar is enabled, we recommend that you turn off this functionality to maintain correct operation of service.

Check the relevant manufacturer's documentation for steps to disable SIP ALG on specific devices.

Proxy support for Webex Calling

Organizations deploy an internet firewall or internet proxy and firewall, to inspect, restrict, and control the HTTP traffic that leaves and enters their network. Thus protecting their network from various forms of cyberattacks.

Proxies perform several security functions such as:

Allow or block access to specific URLs.
Användarautentisering
IP address/domain/hostname/URI reputation lookup
Traffic decryption and inspection

On configuring the proxy feature, it applies to all the applications that use the HTTP's protocol.

The Webex App and Webex device applications include the following:

Webex-tjänster
Customer device activation (CDA) procedures using Cisco Cloud provisioning platform such as GDS, EDOS device activation, provisioning & onboarding to Webex cloud.
Certificate Authentication
Firmware Upgrades
Status Reports
PRT Uploads
XSI Services

If a proxy server address is configured, then only the Signaling traffic (HTTP/HTTPS) is sent to the proxy server. Clients that use SIP to register to the Webex Calling service and the associated media aren’t sent to the proxy. Therefore, allow these clients to go through the firewall directly.

Supported Proxy Options, configuration & Authentication types

The supported proxy types are:

Explicit Proxy (inspecting or noninspecting)—Configure the clients either App or Device with explicit proxy to specify the server to use.
Transparent Proxy (noninspecting)—The Clients aren’t configured to use a specific proxy server address and don’t require any changes to work with a noninspecting proxy.
Transparent Proxy (inspecting)—The Clients aren’t configured to use a specific proxy server address. No HTTP's configuration changes are necessary; however, your clients either App or Devices need a root certificate so that they trust the proxy. The IT team uses the inspecting proxies to enforce policies on the websites to visit and the types of content that aren’t permitted.

Configure the proxy addresses manually for the Cisco devices and the Webex App using:

Platform OS
Device UI
Automatically discovered using Web Proxy mechanisms such as:
- Web Proxy Auto Discovery (WPAD) - Web Proxy Auto Discovery Protocol
- Proxy Auto Config (PAC) files - Proxy Auto-Config Files

While configuring your preferred product types, choose from the following Proxy configurations & authentication types in the table:

Produkt	Proxykonfiguration	Typ av autentisering
Webex för Mac	Manuell, WPAD, PAC	No Auth, Basic, NTLM,^†
Webex för Windows	Manuell, WPAD, PAC, GPO	No Auth, Basic, NTLM, ^†, Negotiate ^†
Webex för iOS	Manuell, WPAD, PAC	Ingen autentisering, grundläggande, sammandrag, NTLM
Webex för Android	Manuell, PAC	Ingen autentisering, grundläggande, sammandrag, NTLM
Webex-webbapp	Supported through OS	No Auth, Basic, Digest, NTLM, Negotiate ^†
Webex-enheter	WPAD, PAC eller manuell	Ingen autentisering, grundläggande, sammandrag
IP-telefoner från Cisco	Manuell, WPAD, PAC	Ingen autentisering, grundläggande, sammandrag
Webex-nätnod för video	Manuellt	Ingen autentisering, grundläggande, sammandrag, NTLM

For legends in the table:

^†Mac NTLM Auth - Machine need not be logged on to the domain, user prompted for a password
^†Windows NTLM Auth - Supported only if a machine is logged onto the domain
Negotiate ^†- Kerberos with NTLM fallback auth.
To connect a Cisco Webex Board, Desk, or Room Series device to a proxy server, see Connect your Board, Desk, or Room Series device to a proxy server.
For Cisco IP phones, see Set Up a Proxy Server as an example for configuring the proxy server and settings.

For No Authentication, configure the client with a proxy address that doesn’t support authentication. When using Proxy Authentication, configure with valid credentials. Proxyservrar som undersöker webb trafik kan störa webb anslutningarna. If this problem occurs, bypassing the not inspecting traffic to *.Webex.com might solve the problem. If you already see other entries, add a semicolon after the last entry, and then enter the Webex exception.

Proxy settings for Windows OS

Microsoft Windows support two network libraries for HTTP traffic (WinINet and WinHTTP) that allow Proxy configuration.WinINet is a superset of WinHTTP.

WinInet is designed for single-user, desktop client applications
WinHTTP is designed primarily for multiuser, server-based applications

When selecting between the two, choose WinINet for your proxy configuration settings. For details, see wininet-vs-winhttp.

Refer to Configure a list of allowed domains to access Webex while on your corporate network for details on the following:

To ensure that people only sign in to applications using accounts from a predefined list of domains.
Använd en proxyserver för att avlyssa förfrågningar och begränsa de tillåtna domänerna.

Proxy-kontroll och certifikatassociering

The Webex App and Devices validate the certificates of the servers when they establish the TLS sessions. Certificate checks that such as the certificate issuer and digital signature rely on verifying the chain of certificates up to the root certificate. To perform the validation checks, the Webex App and Devices use a set of trusted root CA certificates installed in the operating system trust store.

If you have deployed a TLS-inspecting Proxy to intercept, decrypt and inspect Webex Calling traffic. Ensure that the certificate the Proxy presents (instead of the Webex service certificate) is signed by a certificate authority, and the root certificate is installed in the trust store of your Webex App or Webex device.

For Webex App - Install the CA certificate that is used to sign the certificate by the proxy in the operating system of the device.
For Webex Room devices and Cisco multiplatform IP Phones - Open a service request with the TAC team to install the CA certificate.

This table shows the Webex App and Webex Devices that support TLS inspection by Proxy servers

Firewall configuration

Cisco supports Webex Calling and Webex Aware services in secure Cisco and Amazon Web Services (AWS) data centers. Amazon has reserved its IP subnets for Cisco’s sole use, and secured the services located in these subnets within the AWS virtual private cloud.

Configure your firewall to allow communication from your devices, App's applications, and internet-facing services to perform their functions properly. This configuration allows access to all the supported Webex Calling and Webex Aware cloud services, domain names, IP addresses, Ports, and protocols.

Whitelist or open access to the following so that the Webex Calling and Webex Aware services function correctly.

The URLs/Domains mentioned under the section Domains and URLs for Webex Calling Services
IP subnets, Ports, and Protocols mentioned under the section IP Subnets for Webex Calling Services
If you're using the Webex Suite of cloud collaboration services within their organization, Webex Meetings, Messaging, Webex attendant console and other services then ensure you have the IP subnets, Domains/URLs mentioned in these articles are open Network Requirements for Webex Services and Network requirements for Attendant console

If you’re using only a firewall, then filtering Webex Calling traffic using IP addresses alone isn’t supported as some of the IP address pools are dynamic and may change at any time. Update your rules regularly, failing to update your firewall rules list could impact your users' experience. Cisco doesn’t endorse filtering a subset of IP addresses based on a particular geographic region or cloud service provider. Filtering by region can cause severe degradation to your calling experience.

Obs! Cisco doesn't maintain dynamically changing IP address pools hence it isn’t listed in this article.

If your firewall doesn’t support Domain/URL filtering, then use an Enterprise Proxy server option. This option filters/allows by URL/domain the HTTPs signaling traffic to Webex Calling and Webex Aware services in your Proxy server, before forwarding to your firewall.

You can configure traffic using port and IP subnet filtering for call media. Since the media traffic requires direct access to the internet, choose the URL filtering option for signaling traffic.

For Webex Calling, UDP is Cisco’s preferred transport protocol for media, and it recommends using only SRTP over UDP. TCP and TLS as transport protocols for media aren’t supported for Webex Calling in production environments. The connection-orientated nature of these protocols affects media quality over lossy networks. If you have queries regarding the transport protocol, raise a support ticket.

^†^*CUBE media port range is configurable with rtp-port range.
^†^*Media ports for devices and applications that are dynamically assigned in the SRTP port rages. SRTP ports are even numbered ports, and the corresponding SRTCP port is allocated with the consecutive odd numbered port.
If a proxy server address is configured for your Apps and Devices, the signaling traffic is sent to the proxy. Media transported SRTP over UDP flows directly to your firewall instead of the proxy server.
If you’re using NTP and DNS services within your enterprise network, then open the ports 53 and 123 through your firewall.

Quality of Service (QoS)

Allows you to enable tagging of packets from the local device or client to the Webex Calling cloud platform. QoS enables you to prioritize real-time traffic over other data traffic. Enabling this setting modifies the QoS markings for Apps and devices that use SIP signaling and media.

Create a separate QoS profile for Audio and Video/Share since they have different source port range to mark traffic differently.
For Windows Clients: To enable UDP Source Port Differentiation for your organization, contact your local account team. Without enabling, you cannot differentiate between the Audio and Video/Share using the Windows QoS Policies (GPO) because the source ports are the same for audio/video/share. For details, see Enable media source port ranges for Webex App
For Webex Devices, configure the QoS setting changes from the Control Hub device settings. For details, see Configure & modify device settings in Webex-Calling
