4 Definition of Transcoding 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 4

5 Function of Transcoding 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 5

6 Voice Codecs 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) 6

7 Call Set-up in VoIP End-points advertise their capabilities in the protocols (such as SIP) 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 7

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

9 Transcoding Server I have a call for you What do you support? 2 4 OK. I will broker the call on both ends 1 I m calling the phone on the other side 3 I can do G.711 SIP SIP I can do G.729 9

11 Software Solutions for Transcoding 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 Transcoding is CPU intensive that impacts the performance of your VoIP apps. 11

12 Current Hardware Transcoding Solutions 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

41 Media Transcoding: Installation Download Media Transcoding Package: eg: sng-tc-linux-x tgz Untar Package in /usr/src directory -> tar xfz sng-tc-linux-x86-<ver>.tgz -> cd sng-tc-linux-x86-<ver> Install Ethernet Drivers -> cd sng-tc-linux-x86-<ver> -> 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 41

42 Media Transcoding: Installation... Build Sangoma Media Transcoding libraries, configurator and server -> cd sng-tc-linux-x86-<ver> -> 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 42

43 Media Transcoding: Firmware & License 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 <license_key_file> 43

44 Media Transcoding: Asterisk Operation 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 44

45 Media Transcoding: FreeSWITCH Operation 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 <session number> 45

46 Closing 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 46
