SIP Trunking
With
Version 4 or lower
software, the NEC SL1100 system
does not support the simultaneous use of a SIP trunk
interconnection and a SIP trunk carrier connection.
With
Version 5 or higher
software, SIP Multi-profile support is
added. The simultaneous use of a SIP trunk interconnection
and a SIP trunk carrier connection or two SIP carriers at the
same time is supported.
Limitations:
Each profile requires a different number for every SIP trunk port
set in PRG 84-14-06.
Two carriers must be connected using a single route. The system
only supports one gateway.
Only one DNS server can be set for the SL1100 to connect to two
different SIP Carriers.
The NEC SL1100 system restricts an outgoing call under the
following conditions:
SIP configuration failed
SIP registration failed
CPU-B1/VOIPDB daughter board link down
Lack of VOIPDB DSP resource
Lack of bandwidth

SIP Trunking Setup
Use the following steps to initially set up SIP Trunking for the NEC
SL1100 system:
1.
By default, the NEC SL1100 is assigned a static IP address
and runs behind a NAT router.
When using an NEC SL1100 on a LAN behind an NAPT router, forward
port 5060 to the IP address of the NEC SL1100 CPU-B1 (commonly
called the SL1100 CPU) since the signaling is handled by the CPU-B1.
Then, since the media stream (the speech) uses a large range of ports
for the RTP packages, forward the ports (10020~10083) to the IP
address of the
VOIPDB
. Or, use the DMZ option for the
VOIPDB
.
This means that the
VOIPDB
is not actually behind the firewall. This is
achieved by connecting the
VOIPDB
to a physical or virtual DMZ port.
You can also achieve the same result by port forwarding 10020 to
10083.
2.
Define the SIP Carrier account information (user name,
password, domain name/IP address to the provider).
3.
Define the trunk ports as SIP.
