Telephones

Polycom

The CIC server can provision Polycom telephones. This feature greatly reduces setup, configuration, and maintenance time. Polycom selected (101100) as the default DSCP value for SIP signaling. They are using the recommended value (101110) EF for RTP. You can modify this value in the Advanced Options section in the Managed Phone configuration.

Legacy Polycom telephones mark RTP and SIP. The version of the firmware load determines the default values, but you can adjust it in the Sip.cfg file.

Soft phones

For more information about setting the DSCP for soft phones, see the CIC Managed IP Phones Administrator's Guide. The PureConnect QoS driver, by default, marks voice traffic (RTP) with an EF DSCP value. It marks the associated SIP signaling with a CS3 DSCP value. These values are set once you provision the softphone through Interaction Administrator.
