Allocate this VoIP profile to the desired SIP terminal or to the desired SIP
line / SIP tie line. Please note that bandwidth cannot be restricted for
terminals or lines with this VoIP profile. This is suitable, e.g. for SIP terminals
operating on a LAN.
Codec interconnection with bandwidth restriction
You can implement bandwidth restriction with additional VoIP profiles using
an extended codec list. The extended codec list contains definitions for codecs
which are used by the usual SIP terminals. The codecs on this list are for
usage in VoIP profiles and are not directly supported by the Forum 5004/
5008/5012 communications system.
You can load the extended list of codecs as a description file in the
Configurator
of the Forum 5004/5008/5012 communications system on
the
System
:
Components
page. The extended codec list is also a part of data
back-up.
Note:
You can obtain the extended codec list as a description file from
your Proximus agent. This file should not be edited which is why
editing is not supported.
Create a VoIP profile with extended codec entries with the following steps:
1.
Open the
Telephony
:
Extended: VoIP profile
page in the
Configurator
of
the Forum 5004/5008/5012 communications system.
2.
Click on the
Codecs
button. On the following page, select the codecs to be
offered for defining a VoIP profile. Use
Apply
to confirm.
The list contains entries with various classes (“audio”, “image”, “text”, or
“video”) as well as specific bandwidth information for many entries. Partic-
ularly suitable entries are indicated as “recommended”.
3.
Click on the
New
button on the
VoIP profile
page. Enter a designation into
the
Profile name
input field. Determine the permissible codecs in
descending order in the 10 fields. Configure the desired codecs from the
extended codec list in the uppermost fields. Close the list with a fall-back
selection, e.g. with “G.711 A-Law (audio)” and “DTMF (RFC 2833/4733)
(event)”. Use
