Chapter 1 Configuring the Cisco Phone Proxy
Configuring the Phone Proxy
What to Do Next
When using an existing CTL file to configure the phone proxy, you can add additional entries to the file
as necessary. See Creating the CTL File, page 1-19.
Once you have configured the CTL file for the phone proxy, create the TLS proxy instance. See Creating
the TLS Proxy Instance for a Non-secure Cisco UCM Cluster, page 1-21 to add the TLS proxy when
configuring the phone proxy in a non-secure mode or see Creating the TLS Proxy for a Mixed-mode
Cisco UCM Cluster, page 1-21 if the phone proxy is running in a mixed-mode cluster.
Creating the TLS Proxy Instance for a Non-secure Cisco UCM Cluster
Create the TLS proxy instance to handle the encrypted signaling.
What to Do Next
Once you have created the TLS proxy instance, create the phone proxy instance. See Creating the Phone
Proxy Instance, page 1-24.
Creating the TLS Proxy for a Mixed-mode Cisco UCM Cluster
For mixed mode clusters, there might be IP phones that are already configured as encrypted so it requires
TLS to the Cisco UCM. You must configure the LDC issuer for the TLS proxy.
Command Purpose
Step 1
hostname(config)# ctl-file ctl_name
Example:
ctl-file myctl
Creates the CTL file instance.
Step 2
hostname(config-ctl-file)# cluster-ctl-file
filename_path
Example:
hostname(config-ctl-file)# cluster-ctl-file
disk0:/old_ctlfile.tlv
Uses the trustpoints that are already in the existing
CTL file stored in Flash memory.
Where the existing CTL file was saved to Flash
memory with a filename other than
CTLFile.tlv;
for example,
old_ctlfile.tlv.
Command Purpose
Step 1
hostname(config)# tls-proxy proxy_name
Example:
tls-proxy mytls
Creates the TLS proxy instance.
Step 2
hostname(config-tlsp)# server trust-point
_internal_PP_ctl-instance_filename
Example:
server trust-point _internal_PP_myctl
Configures the server trustpoint and references the
internal trustpoint named
_internal_PP_ctl-instance_filename.
