Network Requirements
Network requirements for the Webex Wireless Phone 840 and 860 include:
• Cisco Unified Communications Manager (Unified Communications Manager):
• Minimum: 11.5(1)
• Recommended: 12.5(1) or higher
• Supported Wi-Fi access point.
For supported access point options, see the Webex Wireless Phone 840 and 860 Wireless LAN Deployment
Guide .
The phones use Dynamic Host Configuration Protocol (DHCP) Option 150 or 66 for Unified Communications
Manager server configuration. If the network doesn't provide DHCP Option 150 or 66, or is pointing to the
incorrect Unified Communications Manager server, then you must manually configure the servers in the Cisco
Phone app.
Hosts on the network use DHCP to obtain initial configuration information, including IP address, subnet mask,
default gateway, and Hypertext Transfer Protocol (HTTP) server address. DHCP eases the administrative
burden of manually configuring each host with an IP address and other configuration information. DHCP also
provides automatic reconfiguration of network configuration when devices are moved between subnets. The
configuration information is provided by a DHCP server that is located in the network, which responds to
DHCP requests from DHCP-capable clients. Although the server is referred to as an HTTP server in this
document, the actual communications protocol that is used is HTTP or Hypertext Transfer Protocol Secure
(HTTPS).
To simplify deployment of these devices, configure the phones to use DHCP. Use any Request for Comments
(RFC) 2131 compliant DHCP server to provide configuration information to the phones.
