1. Introduction

SC-385 is a 2 channels VoIP GSM Gateway for call termination (VoIP to
GSM ) and origination (GSM to VoIP). It is SIP based and compatible
with Asterisk. It can make 2 calls simultaneously from SIP VoIP devices
to GSM networks and GSM network to VoIP devices.

2. Function description

2.1 VoIP(SIP)、GSM(SC-385) conversion.

2.2 50 sets of LAN->MOBILE routes setting，50 sets of MOBILE->LAN
routes setting.

2.3 Voice response for setting and status (dial in from mobile).

2.4 Series connections to save bills.

2.5 Standard SIP(RFC2543,RFC3261) protocol，

Communicates with other gateway or Softphone via PC or notebook

6.1 Connect the internet cable from HUB to the ‘WAN’ connector of the
SC-385.

*If you need to stack up more SC-385,you can stack up as follows.

6.2 Connect the antenna and put it in proper position to get the best

signal reception.

6.3 Insert the SIM card from back of the main body. (take the slide off

first).

6.4 Connect the power adaptor. The ‘POWER’ LED should be light up.

7. IP Setting

The operator can setup or query the network parameters by dialing in the
mobile number which it SIM card has been put in the main body. The
status or result is response by voice. In the first 20 seconds after
power-on, the VoIP GSM Gateway enters the IP setting mode. The
operator may dial in the mobile number during this period to set or query
the network parameters.

10.1 Mobile TO LAN Settings

The operator may assign 50 sets of routing rule to transfer the call
incoming from MOBILE to LAN.

The Ssc-385 will transfer to the URL according to the caller ID of the
Mobile.

*CID：

(1) may enter the whole number, e.g. 0911111111
(2) only part of the number (prefix) e.g. 0911* means any number

starting with 0911 will be accepted

-10-

(3) * means all numbers can be accepted

(4) N means the calls without the CID
Please note the priority of the rules. The item which has more digits will
have higher priority. If the digits are the same, then former one gets the
higher priority.

*URL：The IP address to transfer this call

(1) may enter the whole IP address, e.g. 192.168.0.101 or proxy

extension .
(2) If this field is blank or simply ‘N’, it means refuse to transfer.
(3) If an ‘*’ entered, it means 2-stages-dialing. The call will be answered

and prompt dial tone again to receive the IP address as the

destination. The caller may enter the IP such as 192*168*0*101#.

-11-

10.2 Mobile to LAN Speed Dial Settings
When you set Mobile to LAN Speed Dial Settings and Mobile to
LAN at the same time,SC-385 will give priority to Mobile to LAN Speed
Dial Settings.

*The call will be answered and prompt dial tone again. When the caller

may enter the “Num”, system will connect the “URL” as destination.

-12-

10.3 LAN to Mobile Settings
The operator may assign 50 sets of routing rule to transfer the call
incoming from LAN to MOBILE.

The SC-385 will transfer to the mobile number according to the incoming
URL
*URL：The IP address of the incoming call

may enter the whole IP address, e.g. 192.168.0.101 or proxy server’s
extension. If a simple ‘*’ is entered, means no restriction for the
incoming IP address.

-13-

*Call Num：

1. may enter the whole number, e.g. 0911111111

2. a simple *”means 2-stages-dialing. The call will be answered and
prompt dial tone again to receive the called number as the
destination, e.g. 0911111111 or 0911111111#

3. #['d'n]['a'ppp] for one-stage dialing
[...] is option
'd'n means to delete the beginning n codes,

'a'ppp means to add 'ppp' in front.

for example #d2a09 means one-stage dialing,

delete the first 2 codes from your destination number,
then add 09 in front as the new destination number.

20.Setup SC-385 with Asterisk

20.1 Usage
A typical usage of such a gateway is to be able to give a call with your

normal mobile to any destination at voip cost:
Your mobile <----GSM network----> SC-385 <--LAN--> Asterisk
<--internet--> VOIP provider <--whatever--> landline

To do such a call, you just call your SC-385 number (it has its own SIM
CARD), then you get an invitation tone, then you dial the number which
is handled by Asterisk.
If you have some special deals with your mobile operator, like free
special number, you can call your SC-385 for free.
You can then call all around the world from your mobile at voip cost :-)

20.2 SC-385 Configuration
Once you've configured everything in the box, one good advice is to

unplug the power and to restart it. By this way you should have all the
parameters taken into account.

To have the SC-385 to work with Asterisk, you need first to configure the
box.
Here are some screen shots showing all the important parameters.
You have to note that in all the configuration process, the SC-385 is

-37-

considered as extension '103' of the IPBX.
In Bold are the parameters depending on your installation

Here the '#' is important to avoid the two stage dialing when you give a
call from Asterisk to GSM.

-38-

The mobile numbers you give in that page are the authorized mobile
which can call GSM to Asterisk.
These mobile numbers must be defined as your GSM provider displays
the number.
If you don't know how it is displayed, just give a call to the box and check
the number given in the 'Incoming Mob' field of the 'Mobile Status' page.
Any number which is not in that list won't have access to the LAN side, so
to Asterisk.
If you want to allow any number, just set '*' in that field ... but beware of
the bill ;-)

-39-

Once Asterisk configuration is made, you should get 'Registered' on the
Realm1.

-40-

It is very important to use only ulaw or alaw as all DTMF is inband.
So if you want to be able to do some DISA when you call from GSM to
Asterisk, it has to be one of these 2 codecs.

These settings seem to be ok, just adjust ...

20.3 Antenna position
Another important thing is to properly place the provided antenna.

If your GSM reception is good, you should get around 18 or 19 as Signal
Quality in the "Mobile Status" page.
With that level of signal quality, your audio quality will be very good.
On the other end, I've experienced that with a signal quality down to 11,
audio becomes very jerky.
So, maximum signal quality = maximum audio quality.

20.4 Asterisk configuration
Once the SC-385 is set, you have to configure Asterisk.

On that side, you have to setup files as follow :

20.5 sip.conf
; GSM VOIP Gateway SC-385
