SIP user names: 30201, 30202, 30203, 30204 and 30205. This user name is used for the registration on the SIP Server and should be unique on the
SIP server. This field length is limited by 20 symbols and is not limited regarding the use of symbols. If an extension with the given SIP user name
already exists in the Extensions Management table, a next subsequent not used SIP user name will be used instead.
The
Automatically attach to IP Line
checkbox selection is used to automatically attach extensions to IP Lines.
Start From the IP Line
text field requires the number of the new IP Line to be created. The error message “One or more IP Lines in the specified
range are already attached to existing extensions” appears if an IP line with the given numbers already exists in the Extensions Management table.
SIP Server
text field requires the address of the SIP server. The field is not limited regarding symbol usage and length as it can be either an IP
address or a host address (e.g. sip.epygi.com).
SIP Port
text field requires the port number to connect to the SIP server. The SIP Port may only contain digit values, otherwise an error message
"SIP Port is incorrect" will appear. If the SIP server port is not specified, QX1000 will access the SIP server via the default 5060 port.
Registration on SIP Server
checkbox enables the SIP server registration option on the newly created extensions.
Extension Codecs
To establish an IP voice communication, call participants have to use the same codec. When establishing a communication line, this codec is
negotiated. If the caller does not find an appropriate codec, the communication does not take place. To allow communication with all IP callers, it is
helpful to support as many codecs as possible. In this case, all codecs that the system offers should be enabled in the
Codecs
table. On the other
hand, some codecs require quite a high transfer rate of up to 64 kBit/s. If you definitely do not want to use these codecs, make sure they are disabled
in the
Codecs
table.
The
Codecs
table lists the voice and video codecs
supported by the QX1000. Each table entry is assigned a
checkbox that is used to manipulate the entry, for example
to disable, to move it up or down, etc.
The table entries in bold type indicate codecs enabled for
the selected extension/attendant/conference. The enabled
codecs participate in codec negotiation at the call setup.
The order of the enabled codecs is very important. Each
codec in the table has a higher priority than the codecs
below it, and a lower priority than the codecs above it. A
codec placed at the top of the table is used as the
preferred codec. When establishing a call, the system will
try this codec first. If the remote party does not support the
preferred codec, the following codecs will be tried out
strictly in the order given in the
Codecs
table.
Please Note:
Pay attention when configuring Auto
Attendant Codecs as they are used by virtual extensions
for redirecting the incoming calls.
Enable/Disable
enables or disables the selected codec.
Disabled codecs do not participate in codec negotiation,
i.e. they will never be used to for call setup. At least one
codec must be enabled; otherwise voice communication
with an extension/attendant/conference will be impossible.
Select all
selects all entries in the table.
Inverse Selection
performs an inverse selection of the
selected entries. Clicking this button when no entry is
selected will select all entries.
Fig. II-115: Extension Codecs list
Move up
moves the selected codec one level up, increasing the codec's priority.
Move down
moves the selected codec one level down, decreasing the codec's priority.
Make preferred
moves the selected codec to the top of the table, setting its priority to the highest. Clicking the
Make preferred
button when a
disabled codec is selected will first enable the codec and then move it to the top.
Please Note:
The
Call Recording
service is not available, if the call is established with TDVC or G722 codecs.
The following settings are available for user extensions and attendants only:
Out of Band DTMF Transport
enables the DTMF code transmission in parallel with the voice stream. Destination received the DTMF code will play
it locally if it supports the feature too. This helps avoid DTMFs loss in case of heavy traffic. The feature is valuable for all codecs but it is especially
recommended for low bit rate codecs, such as G.729, G.726/16, etc.
Enable T.38 FAX
enables the FAX tone detection and the T.38 codec support for the FAX transmission from/to the FAX machine/modem attached
to the line. It also enables the T.38 codec support for incoming unified FAX messages (fax to mailbox).
Enable Pass Through FAX
enables the FAX tone detection and the G.711 codec support for the FAX transmission from/to the FAX
machine/modem attached to the line. It also enables the G.711 codec support for incoming unified FAX messages (fax to mailbox).
