vi.
Since the QSL output of the ICOMIC-2720 is active high, then the PTT Settings should be
configured as shown below.
vii.
Since the RoIP302M needs to be connected with multiple RoIP302s, the voice codec G.729
should be selected in order to lower the network bandwidth requirement.
viii.
Up to 3 groups can be defined in the Group Settings. Each group consists of remote RoIP302
clients (referred as Soft Lines here) and onboard channels (PTT1, PTT2, PTT3,
GSM). Similar to
RoIP302, each onboard channel can only be assigned to one group. RoIP302M can at the most
accept up to 12 client registrations. This means that these 12 clients (Soft Lines) are split among the
3 groups. In the example below, 12 Soft Lines are assigned to Group 1 and this means that there are
no more lines available for group 2 and 3.
Setting up a RoIP302:
i.
The connection of GM300 to RoIP302 is the same as the one shown in Example 1.
ii.
The Network Setting is the same as that shown in Example 1.
iii.
The DDNS feature should be disabled.
iv.
In the router configuration, DMZ mode should be configured to IP address of the
RoIP302.
v.
The Call Settings should be configured according to the example shown below. The
Group SIP Number must be unique for each RoIP302. The SIP Proxy should be set to the IP of the
RoIP302M. The Auto Dial Number should be set to the Group SIP Number of the RoIP302M. This
is the number to be called when the GM300 Radio is talking.
