3 Voice Transcoding Explained Existing Transcoding Solutions Sangoma Solution – D-Series Transcoding Card Ordering and Pricing Architecture Technical Dive Closing Q&A Agenda 3

4 Transcoding is the direct digital-to-digital conversion of one encoding to another This is usually done in cases where a target device does not support the format or has limited storage capacity that mandates a reduced file size, or to convert incompatible or obsolete data to a better-supported or modern format Transcoding is widely used in multimedia applications such as MMS, Streaming Video and VoIP Definition of Transcoding 4

5 To save bandwidth, VoIP Network engineers sometimes compress the voice signal This is done using CODECs –COders – DECoders Codecs are algorithms (a lot of math) to compress and decompress voice signal –Similar to ripping a CD to MP3 – MP3 is a codec Sometimes called Vocoding Function of Transcoding 5

6 Extensive List of codecs –G.711, G.729, GSM, AMR, G.726, iLBC, G.722.1, etc. Most common in use in wired world are: –G.711 (64kbps) –G.729 (8 kbps) Most common in use in wireless applications: –GSM / AMR Growing in popularity – G (HD voice) Voice Codecs 6

7 End-points advertise their capabilities in the protocols (such as SIP) Call Set-up in VoIP 7 I’m calling you. I can do G.711 I can do G.711 and G.729 Let’s go ahead with G.711 SIP Voice Call

8 SIP Voice Call No common denominator - Call cannot be established Need for a middleman to translate – Transcoding! Sometimes, there is a mismatch 8 I’m calling you. I can do G.711 I can do G.729 SIP No Call

9 Transcoding Server 9 G.711 Voice Call I’m calling the phone on the other side I can do G.711 I can do G.729 SIP I have a call for you What do you support? G.729 Voice Call SIP OK. I will broker the call on both ends 4 4

11 Vocoding is complicated Math (or algorithms) Math takes a lot of processing power It does not leave much room for your telecom application to run Call only accommodate low port counts Software Solutions for Transcoding 11 Software Transcoding is CPU intensive that impacts the performance of your VoIP apps.

12 Existing Solutions are only available for up to 120 channels Not available for lower densities Short list of codec supported –G.711 –G.723 –G.729 Current Hardware Transcoding Solutions 12

41 Download Media Transcoding Package: eg: sng-tc-linux-x tgz Untar Package in /usr/src directory -> tar xfz sng-tc-linux-x86-.tgz -> cd sng-tc-linux-x86- Install Ethernet Drivers -> cd sng-tc-linux-x86- -> cd server/eth_driver ->./install.sh PCIe cards use Broadcom tg3 driver: -> modprobe tg3 PCI cards use Micrel ks8842_pci driver: -> modprobe ks8842_pci Once Ethernet drivers are loaded confirm that new interfaces have been created -> cat /proc/net/dev # check for eth1, eth2 … Give each ethX device a private IP address: eg: /24 On RedHat: system-config-network Media Transcoding: Installation 41

42 Build Sangoma Media Transcoding libraries, configurator and server -> cd sng-tc-linux-x86- -> make -> make install or if you have Astersk installed on the system, also build Sangoma Asterisk Codec -> make asterisk -> make install FreeSWITCH codec is part of FreeSWITCH GIT repository Asterisk Sangoma Transcoding Configuration: -> sngtc_cfg --server --asterisk or -> sngtc_cfg --server --asterisk --astdir=/etc/asterisk Asterisk Sangoma Transcoding Config file /etc/asterisk/sangoma_codec.conf FreeSWITCH Sangoma Transcoding Configuration: -> sngtc_cfg --server --freeswitch or -> sngtc_cfg --server --freeswitch --fsdir=/usr/local/freeswitch/conf/autoload_configs FreeSWITCH Sangoma Transcoding Config file: /usr/local/freeswitch/conf/autoload_configs/sangoma_codec.conf.xml Media Transcoding: Installation... 42

43 Firmware Upgrade Procedure The sngtc_tool is a binary application that contains the latest firmware version. The sngtc_tool will upgrade firmware on all trancoding modules detected. -> sngtc_tool –dev eth1 –firmware License Update Procedure The License update program is not distributed in a sngtc release. It is provided to a customer with a license key that is built using customer hardware information. Customer needs to send Sangoma Support module their hardware information -> sngtc_tool –dev eth1 –list_modules Based on this information, Sangoma Sales will send a package to the customer containing license update application and the license key. The sngtc_tool application contains the up to date license files which will be applied to all sangoma modules detected. -> sngtc_tool –dev eth1 –license Media Transcoding: Firmware & License 43

44 Before starting Asterisk or FreeSWITCH, one must start the Sangoma Transcoding Server. Server autodetects and initializes the Sangoma Transcoding Cards. -> sngtc_server_ctrl start Log file located in /var/log/sngtc_sever.log Check for message: [SNGTC_INFO ] Sangoma Transcoding Server Ready Start Asterisk -> safe_asterisk Load Sangoma transcoding module from CLI (If not automatically loaded) -> module load codec_sangoma.so -> sangoma show translators -> sangoma show transcoding sessions -> sangoma show rtp statistics Media Transcoding: Asterisk Operation 44

45 Before starting Asterisk or FreeSWITCH one must start the Sangoma Transcoding Servier. Server autodetects and initializes the Sangoma Transcoding Cards. -> sngtc_server_ctrl start Log file located in /var/log/sngtc_sever.log Check for message: [SNGTC_INFO ] Sangoma Transcoding Server Ready Start FreeSWITCH -> /usr/local/freeswitch/bin/freeswitch Load Sangoma transcoding module from CLI (If not automatically loaded) -> load mod_sangoma_codec -> show codecs -> sangoma_codec settings -> sangoma_codec sessions -> sangoma_codec stats Media Transcoding: FreeSWITCH Operation 45

46 Software Transcoding is a CPU intensive activity that could impact your VoIP applications Sangoma’s D-Series Hardware Transcoding Cards handle all your applications transcoding with no added latency and work with Asterisk and FreeSWITCH The D-Series cards come in multiple form factors for added deployment flexibility The D100 and D150 offer from 30 to 400 sessions per card The D500 offer 400 to 2,000 sessions per card All D-Series cards offer field upgrades options Closing 46
