router(config-dial-peer)# media [flow-around | flow-through]

•  CUBE po defaultu radi media flow-through, što je i način koji je korišćen za testiranje, tako da nikakva dodatna komanda nije potrebna


•  Da bi se SIP autentifikacija i registracija ostvarila na način na koji Telekom Srbija to očekuje, potrebno je koristiti credentials komandu sa opcijom number: sip-ua credentials number 381116559800 username [email protected] password 7 091F1658485441475E555C7A7B realm ims.telekomsrbija.com

•  number - registrar sa kojim će se SIP trunk registrovati

•  realm - domen na kome definisani kredencijali važe

•  381116559800 u ovom primeru je vodeći broj

•  Ovakva komanda zahteva IOS verzije 15.0(1)XA ili kasniji release: http://www.cisco.com/en/US/docs/ios/voice/command/reference/vr_c6.html#wp1162609

•  IOS 15.0 možda zahteva memory upgrade postojećih ISR G1 rutera: http://www.cisco.com/en/US/products/sw/iosswrel/ps5460/prod_bulletins_list.html


•  U ime IP telefona, CUBE obavlja registraciju E.164 telefonskih brojeva na eksterni SIP registrar komandom registrar:

ip domain name ims.telekomsrbija.com ip host ims.telekomsrbija.com 10.0.0.2 sip-ua registrar dns:ims.telekomsrbija.com expires 3600 host-registrar

•  Ponovna registracija se obavlja na svakih 3600 sekundi

•  host-registrar komanda služi da se host deo diversion i redirect contact SIP header-a popuni ili sa domain name ili sa IP adresom konfigurisanim registrar komandom

•  Cisco Unified Communications Manager ne može direktno da se registruje na SIP trunk servis Telekoma Srbije. Potrebno je koristiti Cisco Unified Border Element za ovu svrhu


ip domain name ims.telekomsrbija.com ip host ims.telekomsrbija.com 10.0.0.2 sip-ua sip-server dns:ims.telekomsrbija.com

dial-peer voice 40 voip description From CUBE to Telecom destination-pattern .T session protocol sipv2 session target sip-server

•  Globalno definisanje SIP server interfejsa i korišćenje u individualnim dial-peer konfiguracijama:


voice service voip

allow-connections sip to sip sip header-passing early-offer forced midcall-signaling passthru

•  Da bi se omogućilo prosleđivanje SIP headera od i ka SIP porukama INVITE, SUBSCRIBE i NOTIFY, potrebno je koristiti komandu header-passing

•  Da bi se očuvao integritet signalizacionih SIP poruka između CUCM i Telekoma, potrebno je koristiti midcall-signaling passthru komandu. SIP poruke sa jednog IP lega se propustaju na drugi IP leg. Napredni servisi bazirani na SIP-SIP RE-INVITE porukama zahtevaju ovu komandu


•  CUCM podržava SIP Offer/Answer model za uspostavu SIP sesije

•  Offer ( tip codeca, IP adresa, portovi, media atributi..) je sadržan u SDP ( Session Description Protocol) polju SIP poruke

•  CUCM podržava Delayed Offer ( Inicijalna SIP INVITE poruka bez SDP) i Early Offer ( inicijalna SIP INVITE poruka sa SDP)

•  Cisco preporučuje upotrebu DO za outbound pozive jer se tada ne zahteva MTP: http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/8x/trunks.html#wp1126420

•  Ako SP zahteva EO, onda je potrebno na CUBE raditi DO-EO konverziju


•  Pri uspostavi SIP trunka od CUCM ka Telekomu Srbija kroz CUBE, jedna od opcija je da se koristi MTP na CUCM. U tom slučaju koristi se fiksni codec! Ako je primarni codec npr. G.711, morao bi da se pravi poseban SIP trunk za npr. G.729 codec

•  Da bi se omogućilo dogovaranje codeca koji će se koristiti između CUCM i Service Provider-a, potrebno je isključiti MTP na CUCM i konfigurisati CUBE da radi Delayed-Offer-to-Early-Offer ka IP PSTN.

•  SIP DO-to-EO konverzija od CUCM ka Telekomu ostvaruje se na CUBE komandom early-offer forced.

•  SIP INVITE poruke ka Telekomu se šalju sa Early Offer opcijom

•  U okviru dial-peer koji radi DO-to-EO konverziju, koristi se voice-class codec koji uključuje G729 i G711 po željenom redosledu

•  SIP profili obezbeđuju mehanizam da se SIP poruke prilagode na granici mreže da bi se obezbedila interoperabilnost između uređaja koji su inače nekompatibilni

CUBE

SIP nekompatibilnost se javlja usled:   Uređaj odbacuje nepoznat header

(vrednost ili parametar) umesto da ga ignoriše

  Uređaj šalje nepravilan podatak u SIP poruci

  Uređaj ne primenjuje (ili pogrešno primenjuje) protokol procedure

  Uređaj očekuje opcioni header vrednost/parametar SIP headera koji može biti implementiran na različite načine

  Uređaj šalje vrednost/parametar koji mora biti promenjen ili uklonjen pre nego uđe/izađe iz enterprise mreže da bi bio u skladu sa određenim pravilima

  Variacije u SIP standardima na temu kako ostvariti određene funkcije


•  SIP profil za promenu media direction atributa SIP ACK, 200 i RE-INVITE poruka koju CUCM šalje kada se radi hold ili transfer:

•  Ovaj SIP profil je primenjen na incoming i outgoing dial-peer

•  Bez ovog SIP profila neće raditi funkcije kao što su hold i forward

•  Primeri konfiguracije SIP profila: http://www.cisco.com/en/US/products/sw/voicesw/ps5640/products_configuration_example09186a0080982499.shtml#sip_messages

•  Kada primi DID (Direct Inward Dialing) poziv, Cisco IOS gateway routira ovaj poziv na osnovu “Req URI” headera.

•  Telekom Srbija rutira na osnovu “To” headera u okviru kojeg šalje DID broj

•  Da bi Cisco IOS Gateway rutirao na osnovu “To” headera, potrebno je koristiti odgovarajuću TCL skriptu

•  Kada se pozove vodeći broj Telekom Srbija u “To” polju ne šalje DID broj, već opis korisnika:

•  U slučaju poziva vodećeg broja od strane PSTN, opis korisnika se uz pomoć TCL skripte menja u lokal 26000 čime je omogućeno prolazno biranje i za ovaj slučaj

•  Za dolazne pozive od PSTN uzimaju se samo zadnje tri cifre pozvanog broja ispred kojih se stavlja 26 kao area code da bi se dobili petocifreni lokali koji se prosleđuju CUCM

•  Called ID translacije za call back se takođe mogu raditi kroz TCL skriptu


•  Telekom Srbija očekuje DTMF po RFC2833

•  RFC2833 je in-band metoda prenosa DTMF tonova kroz RTP. Out-of-band metode su bazirane na prenosu DTMF tonova kroz signalizacione poruke

•  Cisco IOS Gateway podržava prenos DTMF tonova po RFC2833 korišćenjem komande dtmf-relay rtp-nte, tj. RTP with Named Telephone Event (NTE) payload type

Omogućiti H.323-SIP interworking

DTMF kroz H.323 trunk


•  Ako se radi H.323-SIP interworking i zahteva se Early Offer ka SP, onda se mora koristiti H.323 FastStart na strani CUCM.

•  Potrebno je omogućiti Inbound i Outbound FastStart

•  H.323 Fast Start na strani CUCM zahteva upotrebu MTP ( Media termination Point)

•  Za udaljene lokacije, MTP na lokalnom ruteru bi možda bilo bolje rešenje da RTP stream ne bi išao kroz WAN link
