11.2.6 Configuring Convergence End Points (CEP) Phone Detection
About CEP Phone Detection
Convergence is a way to detect a remote IP telephony or video device and apply a policy to the 
connection port based on the type of CEP device found. When a convergence end point (CEP) is 
found, the global policy for that CEP is applied to that port. The following phone detection types 
are available on the Matrix E1 device:
Cisco Phone Detection – Uses the Cisco Discovery Protocol (CiscoDP) to detect IP phones. 
When Cisco phone detection is enabled using the commands described in this section, CiscoDP 
is turned on automatically and will override any administrative settings set by CiscoDP. For 
more information on configuring CiscoDP, refer to 
.
Siemens or Hipath Phone Detection – Uses either an IP address or a UDP / TCP port number for 
detection. By default UDP port 4060 will be used and there is no IP address configured. The 
commands in this section can be used to configure Siemens detection using new parameters.
H.323 Phone Detection – Uses either a group IP address or a UDP / TCP port number for 
detection. Default UDP ports are 1718,1719,1720. Default group address is 224.0.1.41. The 
commands in this section can be used to configure H.323 detection using new parameters.
Purpose
To review, set the status and configure CEP phone detection.
Commands 
Commands to configure CEP phone detection are listed below and described in the associated 
section as shown.

NOTES: Convergence will not work with Port Web Authentication (PWA) enabled. 
Convergence will work with MAC authentication or 802.1x enabled. When an 802.1x 
policy is applied to a port, that policy will take precedence over a convergence policy. 
For information on checking and changing the status of these authentication protocols, 
refer to 
.
There is no way to detect if a Siemens or H.323 phone goes away other than a link 
down. Therefore, if these types of phones are not directly connected to the switch’s port 
and the phone goes away, the switch will still think there is a phone connection and any 
configured policy will remain on the port.
