the system. A Uniform Resource Identier (URI) is a compact string of
characters used to identify or name a resource.
IncomingCallAlertLevel: Use this to select the level of alert when
someone calls. This feature may come in handy when the E20 is set up
in shared lines enviroments. Select between Discreet, Regular and
Silent. The setting may be set separately for Idle and In-call situations.
Default transport: Select the transport protocol to be used over the
LAN.
UDP: The system will always use UDP as the default transport
method.
TCP: The system will always use TCP as the default transport
method.
TLS: The system will always use TLS as the default transport
method. For TLS connections a SIP CA-list can be uploaded using
the web interface. If no such CA-list is available on the system then
anonymous Die Hellman will be used.
Auto: Uses TLS, if possible. If not, TCP will be tried and then UDP.
TLS verify: For TLS connections a CA-list can be uploaded from the
web interface.
On: Set to On to verify TLS connections. Only TLS connections to
servers, whom x.509 certicate is validated against the CA-list, will
be allowed.
O: Set to O to allow TLS connections without verifying them. The
TLS connections are allowed to be set up without verifying the x.509
certicate received from the server against the local CA-list. This
should typically be selected if no SIP CA-list has been uploaded.
Type: Enables SIP extensions and special behaviour for a vendor or
provider.
Standard: Should be used when registering to standard SIP proxy
like OpenSer.
Alcatel: Must be used when registering to a Alcatel-Lucent OmniPCX
Enterprise R7 or later.
Avaya: Must be used when registered to a Avaya Communication
Manager.
Cisco: Must be used when registering to a Cisco CallManager
version 5 or later.
Microsoft: Must be used when registering to a Microsoft LCS or
OCS server.
Nortel: Must be used when registering to a Nortel MCS 5100 or MCS
5200 PBX.
Broadsoft: Must be used when registering to a Broadsoft server.
NonStandard DTMF. Compatibility mode for non-standard DTMF
handling.
CallScreening: Proxy side call management. For Incoming and
outgoing call screening (RFC-5359). Default is O.
On: Enable call screening. The E20 will reply with “305 Use Proxy” for all
incoming SIP invites not from one of the proxies in the SIP Prole.
O: Turn o call screening.
Outbound: O SIP edge proxy to use for signalling. This can be used to
make the device accesible from outside a rewall.
Mailbox: SIP URI of media mailbox (i.e. voicemail, videomail).
MultiWay conference: Address of the MultiWay™ conference server.
To utilize the MultiWay server the address of the server must be
specied in Prole 1. There is no need for further specication (Prole 1
is enough to make it work).
Line: Select between Private and Shared. Private lines are regular
SIP-proles similar to the line concept in TE 2.0 and earlier versions.
A shared line is a BroadWorks extension that is supported in TE 2.1 or
higher. It means that several users (E20s with TE 2.1 and higher) can
share a line. Whenever someone calls the shared line, all of the E20s
that congured with the shared line will start ring. Whoever answers rst
will take the call. However, it is possible for other users of the shared line
to barge-in and join the call. Since Broadworks does not support video
mixing in the current version, the joined call will be audio only. Once one
of the users disconnects from the call, the video is resumed.
BusyLampField: Your Broadsoft BLF URI. When set up correctly this
will give you presence on your BLF enabled contacts. You can set speed
dials to match your BLF contacts.
URI: Key in the URI of the E20 unit.
DisplayName: The name that you send to others when you call them.
