CCL module creates TLS engines of the SIP stack thanks to the client certificates and the CA certificate

 

TPO-CCL_File-Security-ClientCer-DebugInformation

 

 

CCL creates for 1 device 2 TLS engines:

- TLS Client engine is dedicated for the connection from TPO to CuCM on port 5061

- TLS Server engine is dedicated for the connection from CuCM to TPO on the listening port indicated by Listening port. This connection is used for incoming request from CUCM.

 

Example:  the CUCM sends an Invite (Incoming call) on port 5064 to reach the device SEP800000000009

 

The most valuable information are :

 

DeviceId

device ID (EK or TAD profile)

tlsClientEngine

TLS client engine handle

tlsServerEngine

TLS server engine handle

Listening port

Port associated to the TLS Server engine
