Configurable Hostname in Locally Generated SIP Headers

Last Updated: December 20, 2011

This feature allows you to configure the hostname for use in locally generated SIP headers in either of two configuration modes.

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 Action Purpose
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 Action Purpose
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:
