Line-hunting round-robin/circular
The Line Policy expects the
hunting-mode
to be
round-robin
and the
hunting-scan
to be
circular
.
Every new incoming call will be routed alternately to
pots2
and
pots1
.
After a first ring cycle is completed and it has not obtained an answer, other two cycle will start.
The configuration is implemented using the command
enable
.
The
inbound
rule hijacks an incoming call from a trunk to the Line Group (the SIP trunk is
opensip
as in the example below):
set voip user-terminal-group create pluto
set voip user-terminal-group pluto hunting-mode round-robin
set voip user-terminal-group pluto hunting-scan circular
set voip user-terminal-group pluto timerprionoreplay 10
set voip user-terminal-group pluto add pots2
set voip user-terminal-group pluto add pots1
set voip user-terminal-group pluto enable yes
set voip call-mng inbound opensip2pluto source-trunk opensip destination pluto incoming-number all-number
Regarding the creation of
outbound
rules, which have Line Group as source terminal (user-terminal-
group), each of the terminals present in the terminal list will automatically be associated with an
outbound
rule that present the characteristics specified in the
outbound
rule of the user- terminal-
group.
FAX
In VoIP, you can transceive a Fax in two ways:
analog mode
(also called "in-band"), which is in practice equivalent to a normal voice call,
digital
mode
, which is defined by the standard T38 and provides that the Imola's DSP will
do the digital/analog transcoding, interfacing directly with the DSP of the fax machine.
The mode T38 is preferable to avoid the problems of latency and reliability typical of the IP
network, but is not applicable for high-speed fax, i.e. those that operate with the V34standard.
Band mode
After you create a trunk
opensip
, use the command:
set voip trunk sip opensip fax-mode g711-reinvite
T38 mode
After you create a trunk
opensip
, use the command:
set voip trunk sip opensip fax-mode t38-reinvite-g711-reinvite
