The Cisco SPA525G/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 SPA525G/525G2 phones to the Internet and then
use the VPN feature to securely access the company phone network. This feature
works on the Cisco SPA525G/525G2 IP Phone using both SIP and SPCP.
The Cisco SPA525G/525G2 works with the Cisco AnyConnect VPN client and the
following VPN devices:
• Cisco 500 Series Secure Router
Description
Choose yes to enable LLDP-MED for the phone
to advertise itself to devices that use that
discovery protocol. (By default, this setting is
enabled.)
When the LLDP-MED feature is enabled, after the
phone has initialized and Layer 2 connectivity is
established, the phone sends out LLDP-MED
PDU frames. If the phone receives no
acknowledgment, the manually configured
VLAN or default VLAN will be used if applicable.
If the CDP is used concurrently, the waiting
period of 6 seconds is used. The waiting period
will increase the overall startup time for the
phone.
Setting this value causes a delay for the
switch to get to the forwarding state before
the phone will send out the first LLDP-MED
packet. The default delay is 3 seconds. For
configuration of some switches, you might
need to increase this value to a higher value
for LLDP-MED to work. Configuring a delay
can be important for networks that use
Spanning Tree Protocol.
