Inclusief taalgebruik

De documentatie van dit product is waar mogelijk geschreven met inclusief taalgebruik. Inclusief taalgebruik wordt in deze documentatie gedefinieerd als taal die geen discriminatie op basis van leeftijd, handicap, gender, etniciteit, seksuele oriëntatie, sociaaleconomische status of combinaties hiervan weerspiegelt. In deze documentatie kunnen uitzonderingen voorkomen vanwege bewoordingen die in de gebruikersinterfaces van de productsoftware zijn gecodeerd, die op het taalgebruik in de RFP-documentatie zijn gebaseerd of die worden gebruikt in een product van een externe partij waarnaar wordt verwezen. Lees meer over hoe Cisco gebruikmaakt van inclusief taalgebruik.

Over deze vertaling

Cisco heeft dit document vertaald via een combinatie van machine- en menselijke technologie om onze gebruikers wereldwijd ondersteuningscontent te bieden in hun eigen taal. Houd er rekening mee dat zelfs de beste machinevertaling niet net zo nauwkeurig is als die van een professionele vertaler.

Inleiding

Dit document beschrijft de configuratie van de steekproef CLI en GUI van Cisco Unified SIP Proxy (CUSP) met debugs die vier verschillende routingscenario's overeenkomen.

Voorwaarden

Vereisten

Cisco raadt u aan basiskennis van deze onderwerpen te hebben:

Session Initiation Protocol (SIP)
Cisco Unified SIP proxy (CUSP)

Gebruikte componenten

De informatie in dit document is gebaseerd op CUSP.

De informatie in dit document is gebaseerd op de apparaten in een specifieke laboratoriumomgeving. Alle apparaten die in dit document worden beschreven, hadden een opgeschoonde (standaard)configuratie. Als uw netwerk live is, moet u de potentiële impact van elke opdracht begrijpen.

Configureren

In deze sectie worden de configuratie van vier routingscenario's beschreven.

Opmerking: Gebruik de Command Lookup Tool (alleen voor geregistreerde gebruikers) voor meer informatie over de opdrachten die in deze sectie worden gebruikt.

Scenario 1

Call Flow: IP-telefoon 1 — CME — SIP — CUSP — SIP — CUCM — IP-telefoon 2

Bel 408 202 2102 van IP-telefoon 1 die is geregistreerd in CallManager Express (CME) om IP-telefoon 2 te bereiken die is geregistreerd in Cisco Unified Communications Manager (CUCM) via CUSP.

CME fungeert in dit scenario als een openbare telefoonnetwerk (PSTN).

SIP INVITE komt vanuit CME naar CUSP.

Opmerking: Sommige apparaten, zoals CUCM, valideren de Uniform Resource Identifier (URI) van verzoeken voordat ze worden verwerkt, wat betekent dat het eindapparaat mogelijk moet worden geconfigureerd met de Full Qualified Domain Name (FQDN) om dit toe te staan.

In het geval van CUCM moet CUCM > System > Enterprise Parameter > Cluster-breedband Domain Configuration > Cluster Full Qualified Domain Name dezelfde zijn als de naam van de servergroep.

Scenario 2

Call Flow: IP-telefoon 1 — CUCM — SIP — CUSP — SIP — CME — IP-telefoon 2

Bel 202 222 vanaf IP-telefoon 2.408 moet met pre-normalisatie worden uitgevoerd om IP-telefoon 1 te bereiken.

CME treedt in dit scenario op als PSTN.

SIP INVITE komt vanuit CUCM naar CUSP.
