However, when the interface is
set up to work in any of the
SIP modes, particular coding
algorithms won’t be selected
and connection “profiles” will
be defined instead, containing
one or more modes. This is
like that because SIP allows
the participants in a
communication to negotiate
the coding algorithm, so the
one to be finally used will be
limited to the list the caller
presents.
This possibility allows the configuration of the parameters associated to the coding to be used in
Audio over IP networks basing on SIP protocol (Proxy SIP and Direct SIP modes). This option
simplifies the selection of the algorithm to be used in a communication, because most of the
codecs have several tens of encoding algorithms ir order to have the higher compatibility with
other equipments.
When a communication is established using SIP signalling, the codec negotiates the use of the
first compatible encoding algorithm included in a list called SIP CODEC PROFILE. That’s why
you should put these algorithms in order of preference.
Each one of the stored entries includes an alphanumeric identifier and a list of algorithms to
use, organized in order of preference. There several preset profiles in the unit, grouped by
delay, quality… etc.
Profiles can be added, modified or deleted in the “Encoding Profile
Management (SIP)” screen, accessible from the “Tools“ menu in
the upper Menu bar, described in paragraph 5.1.8 of “AEQ
ControlPHOENIX” user’s manual.
3.6. Ethernet Port configuration.
The “
Ethernet config
” menu allows you to configure the IP parameters of the Ethernet port in
the unit.
