2N® NetStar 2N® NetStar as a VoIP gateway Quick guide Version 1.00 www.2n.cz 2N NetStar as a VoIP <-> GSM/UMTS gateway This „how to“ manual will help you to set up 2N® NetStar as a SIP <-> GSM/UMTS gateway. Before you start programming the system it is highly recommended to read configuration manual. 1) Check your license (Global data -> Licences). If you don’t have it please contact https://support.2n.cz. 2) Set up IP address, subnet mask and default gateway of VoIP card (Hardware -> Boards -> VoIP Board) 3) Set up the SIP trunk.  Create a SIP trunk called SIP GW. (Virtual ports -> SIP -> SIP Gateway) o Add RTP interface o Select codecs o Set up the IP address of the other peer and Realm  Set up SIP GW as Default IN – it is important for proper network tones transmission.  Delete all tones from Default IN (Properties -> Tones) 4) Set up GSM/UMTS ports  Create a bundle called GSM (Routing -> Routing objects -> Bundle) and use all GSM ports in this bundle. It is recommended to use cyclical strategy. 5) Create a router - From PBX. (Routing -> Routers -> Called party number Router)  This router will send all calls to GSM. It is very important to specify length of the numbers. In our example GSM prefixes are 6 and 7 and numbers are 9 digits long. 6) Use router From PBX as a from port router on the SIP GW. (Properties -> Routing) 7) Create a router called From GSM. (Routing -> Routers -> Called party number Router)  The purpose of this router is to route all calls from GSM to a predefined extension in the PBX (in our example 111). 8) Use router From GSM as a from port router on Default OUT. (Properties -> Routing) 9) Switch off CLIP normalizing (Global Data -> Localisation)  In case you don’t want NetStar to modify incoming CLI (e.g. strip international prefix) Now you should be able to make inbound and outbound calls.
