Webex Wireless Phone 840 and 860 Administration Guide for Cisco Unified Communications Manager
Product Specific Configuration Fields
Description
Indicates whether the phone advertises the G.722 and
Opus codecs to the Cisco Unified Communications
Manager.
• Use System Default—Defers to the setting
specified in the enterprise parameter Advertise
G.722 Codec.
• Disabled—Does not advertise G.722 or Opus to
the Cisco Unified Communications Manager.
• Enabled—Advertises G.722 and Opus to the
Cisco Unified Communications Manager.
Codec negotiation involves two steps:
Note
1. The phone must advertise the supported
codec to the Cisco Unified
Communications Manager (not all
endpoints support the same set of
codecs).
2. When the Cisco Unified
Communications Manager gets the list
of supported codecs from all phones
that are involved in the call attempt, it
chooses a commonly supported codec
based on various factors, including the
region pair setting.
Identifies the location that the phones use to upload
problem reporting tool (PRT) output files.
This parameter contains the address of the server for
the optional second registration.
Note The purpose of the Secondary SIP Server
is to allow registration of a SIP line to a
separate SIP server, such as a Nurse-call
system integration. It is not intended as a
failover or redundancy solution.
Identifies the far-end port number for the optional
second registration.
Identifies the transport type for the optional second
registration.
