Kev sib cuam tshuam thiab ua ntej nrog ntau txoj kev DTMF Relay
· CUBE sib tham ob qho tib si rtp-nte thiab sip-kmpl yog tias ob leeg txhawb nqa thiab tshaj tawm hauv INVITE tuaj. Txawm li cas los xij, Yog tias CUBE tsis pib sip-kmpl, CUBE tso siab rau txoj kev rtp-nte DTMF kom tau txais tus lej thiab SUBSCRIBE. CUBE tseem lees txais SUBSCRIBE rau KPML. Nws tiv thaiv cov teeb meem qhia ob tus lej ntawm CUBE.
· CUBE sib tham rau ib qho ntawm cov hauv qab no: · cisco-rtp · rtp-nte · rtp-nte thiab kpml · kpml · sip-notify
· Yog tias koj teeb tsa rtp-nte, sip-notify, thiab sip-kpml, qhov INVITE tawm mus muaj SIP Hu-Info header, tso cai-Events header nrog KPML, thiab SDP nrog rtp-nte payload.
· Yog hais tias koj configure ntau tshaj ib tug tawm-ntawm-band DTMF txoj kev, nyiam mus los ntawm siab tshaj mus rau qis tshaj nyob rau hauv qhov kev txiav txim ntawm configuration.
· CUBE xaiv DTMF relay mechanisms siv qhov tseem ceeb hauv qab no: · sip-notify lossis sip-kpml (qhov tseem ceeb tshaj plaws) · rtp-nte · Tsis muaj-Xa DTMF hauv-band
H.323 gateways xaiv DTMF relay mechanisms siv qhov tseem ceeb hauv qab no: · cisco-rtp · h245-signal · h245-alphanumeric · rtp-nte · Tsis muaj-Xa DTMF hauv-band

8 QHOV
Taw qhia rau Codecs
Ib tug codec yog ib tug ntaus ntawv los yog software muaj peev xwm ntawm encoding los yog decoding ib cov ntaub ntawv kwj los yog teeb liab. Lub suab codecs tuaj yeem code lossis txiav txim siab cov ntaub ntawv digital ntawm lub suab. Video codecs pab compression lossis decompression ntawm cov yees duab digital. CUBE siv cov codecs los nthuav cov suab digital samples kom txo kev siv bandwidth ib hu. Tshooj lus no piav qhia txog lub hauv paus ntawm encoding digital suab samples siv codecs thiab yuav ua li cas rau configure lawv.
· Vim li cas CUBE Xav Tau Codecs, nyob rau nplooj 51 · Lub Suab Media Transmission, nyob rau nplooj 52 · Lub Suab Kev Tshawb Fawb, ntawm nplooj 53 · VoIP Bandwidth Requirements, nyob rau nplooj 54 · Txhawb Suab thiab Video Codecs, nyob rau nplooj 56 · Yuav ua li cas Configure Codecs, nyob rau page 57 · Configuration Examples rau Codecs, ntawm nplooj 62
Vim li cas CUBE Xav Tau Codecs
CUBE siv cov codecs los nthuav cov suab digital samples kom txo kev siv bandwidth ib hu. Xa mus rau Table 14: Codec thiab Bandwidth Information, nyob rau nplooj 54 kom pom kev sib raug zoo ntawm codec thiab bandwidth siv. Configuring codecs ntawm ib tug ntaus ntawv (configured li CUBE) tso cai rau lub ntaus ntawv los ua ib tug demarcation point ntawm ib tug VoIP network thiab tso cai rau ib tug hu xov tooj los tsim kom tau tsuas yog yog hais tias tus xav codec cov txheej xwm txaus siab. Tsis tas li ntawd, kev nyiam tuaj yeem siv los txiav txim siab qhov twg codecs raug xaiv dua lwm tus. Yog tias tsis xav tau kev lim dej codec, CUBE kuj txhawb kev sib tham ntawm cov codec pob tshab. Qhov no ua rau muaj kev sib tham ntawm cov ntsiab lus kawg nrog CUBE tawm hauv cov ntaub ntawv codec tsis tau kov. Cov duab hauv qab no qhia tias kev sib tham codec ua li cas ntawm CUBE. Ob lub VoIP huab yuav tsum tau sib txuas. Hauv qhov xwm txheej no, ob qho tib si VoIP 1 thiab VoIP 2 tes hauj lwm muaj G.711 a-txoj cai teeb tsa raws li cov codec nyiam.
Cisco Unified Ciam Teb Element Configuration Guide Los ntawm Cisco IOS XE 17.5 51

Kev txwv rau Voice-Class Codec Pob tshab Daim duab 11: Codec Kev Sib Tham ntawm CUBE

CUBE Fundamentals thiab Basic Setup

Hauv thawj example, lub CUBE router tau teeb tsa los siv G.729a codec. Qhov no tuaj yeem ua tiav los ntawm kev siv tus lej codec uas tsim nyog ntawm ob tus neeg hu xov tooj VoIP. Thaum hu tau raug teeb tsa, CUBE yuav lees txais G.729a nkaus xwb, yog li cuam tshuam rau kev sib tham codec. Nyob rau hauv lub thib ob example, CUBE dial cov phooj ywg tau teeb tsa nrog lub pob tshab codec thiab qhov no tawm ntawm cov ntaub ntawv codec uas muaj nyob rau hauv kev hu xov tooj tsis raug cuam tshuam. Vim hais tias ob qho tib si VoIP 1 thiab VoIP 2 muaj G.711 a-txoj cai raws li lawv thawj qhov kev xaiv, qhov tshwm sim hu yuav yog G.711 a-txoj cai hu.
Kev txwv rau Voice-Class Codec Pob tshab
· Thaum siv lub suab-chav kawm codec pob tshab, tsuas yog qhov kev pom zoo dhau los (tsis muaj lim). Codec filtering yog ua tiav ntawm SDP tam sim no hauv cov lus teb thiab thawj codec raug xa mus rau lwm sab.
· CUBE tsis txhawb Early-Offer to Delayed-Offer (EO-DO) hu flows.
Nco ntsoov Koj tuaj yeem siv 'pass-thru cov ntsiab lus sdp', yog tias koj tsis xav koom nrog CUBE hauv kev sib tham codec.
Suab Media Transmission
Thaum muaj kev hu xov tooj VoIP, siv cov cim qhia, lub suab digitized samples yuav tsum tau kis. Cov suab samples feem ntau hu ua lub suab xov xwm. Lub suab xov xwm raws tu qauv pom nyob rau hauv ib puag ncig VoIP yog cov hauv qab no:
· Real-Time Transport Protocol (RTP)–RTP yog txheej txheej 4 raws tu qauv uas yog encapsulated hauv UDP ntu. RTP yog lub suab tiag tiag digitized samples v hu.

CUBE Fundamentals thiab Basic Setup

Kev Tshawb Fawb Lub Suab

· Real-Time Control Protocol (RTcP)–RTcP yog ib tug khub raws tu qauv rau RTP. Ob qho tib si RTP thiab RTcP ua haujlwm ntawm Txheej 4 thiab yog encapsulated hauv UDP. RTP thiab RTCP feem ntau siv UDP chaw nres nkoj 16384 txog 32767, txawm hais tias cov kab no yuav txawv raws li kho vajtse platform. Txawm li cas los xij, RTP siv cov lej chaw nres nkoj hauv qhov ntau, qhov RTcP siv cov lej chaw nres nkoj khib. Thaum RTP yog lub luag haujlwm nqa lub suab ntws, RTcP nqa cov ntaub ntawv hais txog RTP kwj xws li latency, jitter, pob ntawv, thiab octets xa thiab tau txais.
· Compressed RTP (cRTP)-Ib qho ntawm cov teeb meem nrog RTP yog nws cov nyiaj siv ua haujlwm. Tshwj xeeb, qhov sib xyaw IP, UDP, thiab RTP headers yog kwv yees li 40 bytes hauv qhov loj me, thaum lub suab nrov payload loj ntawm VoIP network tsuas yog 20 bytes, uas suav nrog 20 ms ntawm lub suab los ntawm lub neej ntawd. Nyob rau hauv tas li ntawd, lub header yog ob zaug qhov loj ntawm lub payload. cRTP yog siv rau RTP header compression thiab tuaj yeem txo 40-byte header rau 2 lossis 4 bytes loj (nyob ntawm seb UDP checksums puas siv), raws li qhia hauv daim duab hauv qab no.

· RTP ruaj ntseg (sRTP)– Txhawm rau pab tiv thaiv tus neeg tawm tsam los ntawm kev cuam tshuam thiab kev txiav txim siab lossis muaj peev xwm tswj xyuas cov pob ntawv suab, sRTP txhawb kev nkag mus ntawm RTP pob ntawv. Tsis tas li ntawd, sRTP muab cov lus lees paub, kev kuaj xyuas kev ncaj ncees, thiab kev tiv thaiv kev tawm tsam rov qab.
VPN thev naus laus zis zoo li IP Kev Ruaj Ntseg (IPSec) yuav raug siv los tiv thaiv kev khiav tsheb ntawm qhov chaw. Kev nkag mus rau sRTP kev khiav tsheb ntawm qhov chaw sib kis tau tshwm sim hauv kev nkag mus encrypted tsheb khiav, ntxiv cov nyiaj siv ua haujlwm tseem ceeb thiab kev xav tau bandwidth. Yog li nws tau pom zoo tias sRTP yog siv rau lub suab tsheb, thiab cov tsheb no tsis suav nrog IPSec encapsulation. sRTP siv tsawg dua bandwidth, muaj tib theem ntawm kev ruaj ntseg, thiab tuaj yeem siv los ntawm cov khoom siv ntawm txhua qhov chaw vim tias qhov them nyiaj tau los thiab raug txiav tawm ntawm lub suab kawg. Vim tias cov ntsiab lus kawg tuaj yeem yog lub xov tooj ntawm tes, kev ruaj ntseg ua raws li xov tooj.
Kev Tshawb Fawb Lub Suab
Voice Activity Detection (VAD) yog ib lub tshuab uas ua haujlwm nrog tib neeg lub suab sib tham, feem ntau uas ib tus neeg mloog thaum lwm tus tham. VAD faib cov tsheb khiav raws li kev hais lus, tsis paub, thiab ntsiag to. Kev hais lus thiab tsis paub them nqi raug thauj, tab sis kev ntsiag to poob. Qhov no suav txog kwv yees li 30 feem pua ​​​​ntawm cov nyiaj khaws cia hauv bandwidth dhau sijhawm.
VAD tuaj yeem txo tus nqi bandwidth xav tau los ntawm kev tshaj tawm xov xwm. Txawm li cas los xij, VAD muaj ob peb yam tsis zoo uas yuav tsum tau xav txog. Vim tias tsis muaj pob ntawv xa mus thaum nyob ntsiag to, tus neeg mloog tuaj yeem tau txais kev xav tias tus neeg tham tau raug txiav. Lwm tus yam ntxwv yog tias nws yuav siv sij hawm ib pliag rau VAD kom paub txog cov lus hais tias tau pib dua, thiab vim li ntawd, thawj feem ntawm kab lus tuaj yeem raug txiav. Qhov no tuaj yeem cuam tshuam rau pawg neeg mloog. Suab paj nruag ntawm Hold (MoH) thiab fax tuaj yeem ua rau VAD ua tsis tau zoo vim tias cov kwj tawm tsis tu ncua.
VAD tau qhib los ntawm lub neej ntawd hauv CUBE hu rau cov phooj ywg ntev npaum li tus codec xaiv kev txhawb nqa
