Configuring SSL VPN on the Cisco SPA 525G/525G2
The Cisco SPA 525G/525G2 can be used in a virtual private network (VPN) to
allow users secure access to the office phone network from remote locations.
Users can connect their Cisco SPA 525G/525G2 phones to the Internet and then
use the VPN feature to securely access the company phone network. This feature
works on the Cisco SPA 525G/525G2 IP Phone using both SIP and SPCP.
The Cisco SPA 525G/525G2 works with the Cisco AnyConnect VPN client and the
following VPN devices:
• Cisco 500 Series Secure Router
• Cisco 5500 Series Adaptive Security Appliance
• Cisco Unified Communications 520 Series
You must configure the SSL VPN device to ensure proper routing of voice data
with desired VLAN and QoS at the end of the SSL VPN server. The following
restrictions apply:
• HTTP proxy is not supported.
• SSL client certificate verification is not supported.
• CDP and VLAN tagging and QoS for the voice and PC port are not
supported on the SSL VPN tunnel.
Because using the VPN requires internal phone resources, performance can suffer
if using memory-intensive applications or configurations on the phone when the
phone is connected using the VPN. The following restrictions apply:
• Only the G.711 Audio Codec is supported.
• SRTP for secured audio is not supported.
• Video monitoring is not supported.
