How to set up connection to the opposite device (PBX)
For the setting of the trunk between the VoiceBlue Next and your PBX you need to configure SIP
proxy (GSM→IP) for GSM incoming calls. SIP proxy (IP→GSM) is designed for secure
communication just with traffic from your PBX. You can specify the IP address and port which
will accept SIP packets from.
In case you leave there 0.0.0.0 in SIP proxy(IP->GSM) gateway will be open for traffic from all
IPs.
!!!! This can lead to misuse of equipment by an unauthorized person !!!!

How to configure LCR table
Situation…
Let’s say we have SIM cards of two GSM operators:
a)
T-mobile: Using the following prefixes (602, 606, 607, 723, 724) and it requires you to
dial the number from your mobile phone with the international prefix (+420). All
numbers have a nine digit length with the operator prefix but without the international
prefix.
b)
Vodafone: Using the following prefixes (901, 902, 907, 909) and requires you to dial the
number with the prefix (+420). All numbers have a nine digit length with the operator
prefix and without “+420”.
First we have to assign modules to two GSM outgoing groups (for each operator).The first
step we have to do is to place the SIM cards into the SIM holders. We will start with modules
0 using the T-mobile operator SIM. Module 2 will follow the same procedure but using the
Vodafone SIM.
