Specify essential Subscriber Gateway information

This step is mandatory.

Enter the following information.


Parameter

Description
Description A text string used in the EMS System Explorer to identify this Subscriber Gateway. Specify a string of up to 64 characters, which must not match the description of any other Trunk / Access Gateway or Subscriber Gateway.
Customer information A text field that can be used to store information about the Subscriber Gateway, for example the address of the customer associated with it. This field is optional; you can supply up to 64 characters of free-form text. The text wraps to the width of the field on screen, or you can use the Enter key to force linebreaks. The total contents of all six Customer information fields must not exceed 164 characters.
Customer information 2 A text field that can be used to store additional information about the Subscriber Gateway. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters.
Customer information 3 A text field that can be used to store additional information about the Subscriber Gateway. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters.
Customer information 4 A text field that can be used to store additional information about the Subscriber Gateway. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters.
Customer information 5 A text field that can be used to store additional information about the Subscriber Gateway. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters.
Customer information 6 A text field that can be used to store additional information about the Subscriber Gateway. This field is optional; you can supply up to 32 characters of free-form text. The total contents of all six Customer information fields must not exceed 164 characters.
IP address The IP address of this Subscriber Gateway, used to send gateway control commands. This parameter is optional if you have specified a Domain name that can be resolved to an IP address using the NE's Domain Name Services settings. Specify a standard dotted-decimal IP address.
Domain name Domain name for the Subscriber Gateway. This parameter is required if the Subscriber Gateway uses authentication; otherwise it is optional if you have specified the IP address.
  • If you specify a domain name, this name (rather than the IP address) is used in messages to the Media Gateway, unless the selected Media Gateway Model's Fix bits parameter includes the value Use IP Address, not domain name.
  • If this fix bit is set, or if you do not specify a domain name, the IP address is used instead.
Both relative and absolute domain names are supported in this field. A relative domain name is made up of letters A-Z (either uppercase or lowercase), digits, and hyphens. The first character must be a letter. An absolute domain name is a list of one or more relative domain names separated by dot (period) characters. Note that the domain name is used in calculating the HTTP digest used for authentication. If the Subscriber Gateway uses authentication and you change the domain name, you will need to specify the password again to force the EMS to create a new HTTP Digest.
Media Gateway model The Media Gateway model that describes this gateway. Select from the displayed list of Media Gateway models for subscriber gateways.
Preferred location of Trunk Gateway Specifies the location for Trunk / Access Gateways that should be used to route calls for this object where possible (to reduce unnecessary long-distance traffic when a call can be routed locally). Select from the displayed list of available Location objects or None (no location).
Authentication required This field appears only if the selected Remote Media Gateway Model's Control protocol is set to MGCP. Specifies whether the Subscriber Gateway's communications with the NE require authentication using HTTP Digest Security as defined in RFC2617. You can change this field only if the Remote Media Gateway Model specifies that authentication is optional. If the Remote Media Gateway Model specifies that authentication is mandatory, or that it is not required, this field is read-only. If authentication is required, you must specify the Domain name.
Password This field appears only if authentication is required. The password that is used to calculate the HTTP Digest. The password is not displayed in the EMS and you cannot view it, although you can change it to a new value if necessary. Specify a text string of 6 - 15 characters. Note that the HTTP Digest is calculated from the Subscriber Gateway's Domain name and the NE's system name as well as the Password field. If you change either of these two names, you will need to specify the password again to force the EMS to create a new HTTP Digest for the Subscriber Gateway.
Confirm password This field appears only if authentication is required. To confirm that you have typed the password correctly, type it again in this field. The characters you type must exactly match the characters you typed in the Password field.
