4 4 Mediatrix FXO unit with Asterisk This document outlines the configuration steps required to connect a Mediatrix FXO unit with a 6FXO/2FXS card to an Asterisk open-source telephone system. In the scenario used throughout this document, the Mediatrix 3732 (1 PRI, 6 FXO/2FXS) is used to: Interface a PBX with an IP-PBX; Provide PSTN access via analog lines; Provide IP connectivity to analog phones and fax machines. The Asterisk IP-PBX provides: Call routing, Dial Plan # Including routes to local PSTN gateways Telephony services (voic , call forwarding, etc,) to IP users; SIP Endpoints management; Auto-Attendant.

5 Requirements Asterisk server properly installed Mediatrix 4102S and the IP phone are correctly configured with the IP-PBX and are able to make calls. 5

6 6 Configuration of the PBX Trunk Configuring the Asterisk - PBX Trunk 1) In the sip.config configuration file, create a new extension by adding the following: Extension Description [PBXTRUNK] The SIP username used for calls coming from the PBX. type=peer This is part of the method used by the Asterisk server to match incoming INVITES to this user. host= This means the extension will not register to the Asterisk server. This is the IP address of the Mediatrix port=5061 Port used for requests to and from the Mediatrix unit. nat=no The Mediatrix unit is not behind a NAT. qualify=no No keep alive is used. canreinvite=no No Re-Invite is sent to this extension. dtmfmode=info The DTMF is sent/received in SIP INFO messages. context=frompbx This is the context where the call from this extension is sent. It is the same context for the IP phone and the Mediatrix 4102S. secret=trunkpassword The SIP authentication password t38pt_udptl=yes This allows T.38 fax to be sent by this trunk. This setting is set to no

7 Extension 7 Description for the IP phone and the Mediatrix 4102S. 2) In the extensions.conf, add a context for calls coming from the PBX: Extension Description [FromPBX] exten =>_1XX,1,Dial(SIP{EXTEN},40,) This allows the PBX users to reach extensions 100 to 199. The Asterisk server will make the extension ring for 40 seconds. 3) Still in extensions.conf, modify the context of the extensions to allow them to send calls to the PBX: Extension Description [InternalExtensions] exten =>_1XX,1,Dial(SIP/ ${EXTEN},40,) exten =>_2XX,1,Dial(SIP/ ${EXTEN}@PBXTrunk,40,) This allows the IP phone and Mediatrix 4102S to reach the PBX extensions 200 to ) Reload the Asterisk settings by connecting to the Asterisk CLI (asterisk -r) and typing the reload command. 5) If you want to use the T.38 protocol to transfer faxes, you can follow the procedure of the Configuration Notes Mediatrix 41xx With Asterisk web Adding the PBX Gateway (p. 7) Adding the PBX Gateway Before you start Make sure your PRI interface has both Physical and Signalling up before starting. 1) Go to SIP > Gateways. 2) In the General Configuration table, type PBX-Gateway in the blank field under the Name column. 3) Click on. 4) In the Port field, type 5061.
