Prerequisites for Configurable Hostname in Locally Generated SIP Headers

Cisco Unified Border Element

  • Cisco IOS Release 12.4(2)T or a later release must be installed and running on your Cisco Unified Border Element.

Cisco Unified Border Element (Enterprise)

  • Cisco IOS XE Release 2.5 or a later release must be installed and running on your Cisco ASR 1000 Series Router.

Restrictions for Configurable Hostname in Locally Generated SIP Headers

  • Dial-peer-specific configuration takes precedence over more general gateway-wide configuration.

How to Configure the Hostname in Locally Generated SIP Headers

Configuring Hostname in Locally Generated SIP Headers at the Global Level

To configure the local hostname in global configuration mode for use in locally generated URLs, complete the task in this section.


Note

Dial-peer-specific configuration takes precedence over more general gateway-wide configuration.

SUMMARY STEPS

    1.    enable

    2.    configure terminal

    3.    voice service voip

    4.    sip

    5.    localhost dns: local-host-name-string

    6.    exit


DETAILED STEPS
     Command or ActionPurpose
    Step 1 enable


    Example:
    Router> enable
     

    Enables privileged EXEC mode.

    • Enter your password if prompted.

     
    Step 2 configure terminal


    Example:
    Router# configure terminal
     

    Enters global configuration mode.

     
    Step 3 voice service voip


    Example:
    Router(config)# voice service voip
     

    (Required) Enters the voice-service VoIP configuration mode

     
    Step 4 sip


    Example:
    Router(config-voi-serv)# sip
     

    (Required) Enters the SIP configuration mode.

     
    Step 5 localhost dns: local-host-name-string


    Example:
    Router(conf-serv-sip)# localhost dns:host_one
     

    (Optional) Globally configures the gateway to substitute a DNS hostname or domain as the localhost name in place of the physical IP address in the From, Call-ID, and Remote-Party-ID headers in outgoing messages:

    • dns: local-host-name-string --Alphanumeric value representing the DNS domain (consisting of the domain name with or without a specific hostname) in place of the physical IP address that is used in the host portion of the From, Call-ID, and Remote-Party-ID headers in outgoing messages.

    • This value can be the hostname and the domain separated by a period (dns: hostname.domain) or just the domain name (dns: domain). In both case, the dns: delimiter must be included as the first four characters.

     
    Step 6 exit


    Example:
    Router(conf-serv-sip)# exit
     

    Exits the current configuration mode.

     

    Configuring Hostname in Locally Generated SIP Headers at the Dial-Peer-Specific Level

    To configure the local hostname in dial-peer-specific configuration mode for use in locally generated URLs, complete the task in this section.


    Note

    This configuration takes precedence over global configuration.

    SUMMARY STEPS

      1.    enable

      2.    configure terminal

      3.    dial-peer voice tag voip

      4.    voice-class sip localhost dns: [hostname .]domain [preferred]

      5.    exit


    DETAILED STEPS
       Command or ActionPurpose
      Step 1 enable


      Example:
      Router> enable
       

      Enables privileged EXEC mode.

      • Enter your password if prompted.

       
      Step 2 configure terminal


      Example:
      Router# configure terminal
       

      Enters global configuration mode.

       
      Step 3 dial-peer voice tag voip


      Example:
      Router# dial-peer voice 100 voip
       

      (Required) Enters dial-peer configuration mode for the specified dial peer.

       
      Step 4 voice-class sip localhost dns: [hostname .]domain [preferred]


      Example:
      Router(config-dial-peer)# voice-class sip localhost dns:example.com
       

      (Optional) Configures individual dial peers to override global settings on the gateway and substitute a DNS hostname or domain as the localhost name in place of the physical IP address in the From, Call-ID, and Remote-Party-ID headers in outgoing messages:

      • dns: local-host-name-string --Alphanumeric value representing the DNS domain (consisting of the domain name with or without a specific hostname) in place of the physical IP address that is used in the host portion of the From, Call-ID, and Remote-Party-ID headers in outgoing messages.

      • This value can be the hostname and the domain separated by a period (dns: hostname.domain) or just the domain name (dns: domain). In both case, the dns: delimiter must be included as the first four characters.

       
      Step 5 exit


      Example:
      Router(config-dial-peer)# exit
       

      Exits the current configuration mode.

       

      Verifying the Hostname in Locally Generated SIP Headers

      To verify the hostname in locally generated SIP headers for global or dial-peer-specific configuration, use the following show commands:

      • show call active voice

      • show call history voice

      SUMMARY STEPS

        1.    Use the show call active voice command to display output when the local hostname is enabled:

        2.    Use the show call history voice to display output when the local hostname is enabled:


      DETAILED STEPS
        Step 1   Use the show call active voice command to display output when the local hostname is enabled:
