14.3.8 Configuring Convergence End Points (CEP) Phone Detection

About CEP Phone Detection
Convergence is a method 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 CEP detection is applied to the user on that port. The following phone
detection types are available on Matrix DFE devices:
•
Cisco Phone Detection – Uses the Cisco Discovery Protocol (CiscoDP) to detect IP phones.
When using Cisco phone detection, CiscoDP must be enabled and configured properly as
described in Section
•
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 UDP / TCP port number with multicast 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. A second default H.323 detection excludes the default group
address.
•
SIP Phone Detection – Uses either a UDP / TCP port number with multicast group IP address or
a UDP / TCP port number for detection. Default UDP / TCP port is 5060 and a multicast IP of
224.0.1.75. A second default SIP detection excludes the default group address.
NOTE: There is no way to detect if a Siemens, SIP 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. Detected CEPs will be
removed from the connection table if they do not send traffic for a period of time equal to
the etsysMultiAuthIdleTimeout value. Additionally, CEPs will be removed if the total
duration of their sessions exceeds the time specified by etsysMultiAuthSessionTimeout.
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.
