1 Technical Communication 1201 Norphonic emergency rugged telephone on Alcatel-Lucent OmniPCX Enterprise This document describes configuration procedure for your Alcatel-Lucent OmniPCX Enterprise PBX in order to operate with the Norphonic Emergency phones. Detailed description is provided to assist engineers in configuring Alcatel-Lucent OmniPCX Enterprise and the Norphonic Emergency Telephones. The configuration is done and tested in lab, using OmniPCX Enterprise R10, j c and the Norphonic Emergency Rugged Telephone V8. The procedure requires a minimum knowledge to SIP basics, linux, ftp, and wireshark usage. This document includes SIP traces with successful communications for engineers to compare with on-site traces. The on-site network must provide the Norphonic Phones with IP address and TFTP server providing configuration files. Learn more about our innovations at At Norphonic, we produce Heavy Duty VoIP Telephones for emergency and industrial areas. Our vision is based on a unified and consistent approach to delivering products that can interface with other communication systems, thereby reducing costs and eliminating inefficiencies of using proprietary and non-reusable solutions.

5 Setting up Alcatel SIP system Know your environment To ensure parameters are set up correctly, please note the following information: Definition Description Value in example $_SIPNetworkNumber Find an unused network number in Translator Network Routing Table $_SIPTrunkGroup A free Trunk Group ID 10 $_OXENodeNumber Locate your Node number in System Node Number $_OXEIPAddress Defined in netadmin installation $_OXEHostname Defined in netadmin installation demo 10 1 The values will be referenced as defined in the first column. Important prerequisites RTP Direct IP > IP Parameters: Direct RTP For H323 Terminals True GF Diversion on joining must be disabled to ensure correct forwarding of calls. System > Other System Param. > External Signaling Parameters: gf diversion on joining False Start Configuration Make sure your SIP Network Number is defined as ABC_F Translator > Network Routing Table: Review/modify [$_SIPNetworkNumber] Protocol Type ABC_F Page 1

Trunk Groups: Create Trunk Group ID Trunk Group Type Remote Network Node Number Q931 Signal variant T2 Specification $_SIPTrunkGroup T2 $_SIPNetworkNumber $_OXENodeNumber ABC_F SIP Configure the virtual access on the trunk Trunk Groups > Trunk Group [$_SIPTrunkGroup] : Review/modify Virtual access for SIP Define an even number of accesses to define how many simultaneous calls needed. Each access provides 30 simultaneous calls. Select Compression Type The selection made here defines the OXE s codec offer to SIP UA. G711 will make OXE offer the uncpmpressed G711 codec on this specific Trunk. Selecting Default points to System Other System Param. - Compression Parameters - Compression Type Trunk groups Trunk Group[$_SIPTrunkGroup] : Review/Modify IP Compression Type Default The Compression Type selected in System Parameters control which codec is used when IP Domain requires use of compression.

Using motortrace This procedure make sipmotor engine create descriptive logs directly to traced. Initiate a telnet sessions to the OXE, using your telnet client of choice. After logging in, disable the auto logout mechanism by command: (1)norphonic> timout 0 timout disabled.

Using tcpdump This method copies data traffic on the network for the purpose of analyzing with an external application. Initiate a telnet sessions to the OXE, using your telnet client of choice. After logging in, disable the auto logout mechanism by command: (1)norphonic> timout 0 timout disabled. In the telnet session, switch to user root and enter the root password.

[root@norphonic root]# cd /usr4/backup/immed/ [root@norphonic IMMED]# Start a dump of network traffic to and from the IP assigned your Norphonic Emergency phone and save the result to a file. The information is written binary to the.cap file and must be analyzed with wireshark. The wireshark tool is not described here. Refer to for additional information. Description of switches: -s 0 set snaplength to infinite and make tcpdump save the entire content of each tcp package, -w trace01.cap write the captured data to the file trace01.cap, -I eth0 ensure tcpdump capture data on Ethernet interface eth0 and host limit the capture to traffic to and from [root@norphonic IMMED]# tcpdump -s 0 -w trace01.cap -i eth0 host tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size bytes There will be no output in terminal during capture. Break the ongoing capture with a Ctrl-C when capture is considered done. The terminal will answer with statistics of the finished tcpdump job. 11 packets captured 11 packets received by filter 0 packets dropped by kernel [root@norphonic IMMED]# Retrieve the.cap file from /usr4/backup/immed by ftp and open for analyzing with Wireshark.

26 Questions and Answers Q: Norphonic phone is registered but calls are rejected. Call to Norphonic phone is fine. A: The Alcatel is set up to authenticate all incoming calls. Change SIP SIP Proxy - Only authenticated incoming calls to False. Q: The Norphonic Phone registers with the proxy but cannot make calls. Alcatel ISSUES a 502 Bad Gateway message A: The phone offers both G711 as well as G729 codec choice to OXE. If OXE is set to require Compression for this call due to IP Domain settings and Compression Type is set to G723 in System Parameters, the call is rejected with a 502 Bad Gateway message. Q: The Norphonic phone is challenged with a Status: 407 Proxy Authentication Required and call establishment from Norphonic phone is failing. A: Make sure SIP SIP Proxy parameter Only authenticated incoming calls is set to False. Restart Alcatel SIP Motor engine to ensure proper parameter adaptation. Page 22
