This step is mandatory if you are adding new subscribers and the Number status field is set to Normal, Ported to, or Non-geographic. Otherwise there are no mandatory fields to fill in and you can ignore this step.
Enter the following information.
Parameter |
Description |
Call Agent signaling type | The type of signaling used by this subscriber's telephone to connect to the NE. This field appears only if Number status is set to Normal, Ported to, or Non-geographic. Values:
The value SIP is not valid if you are configuring connection information for PBX Lines. |
Gateway | The Trunk / Access Gateway or Subscriber Gateway that owns the Access Device that this line uses to connect to the NE. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Click on the search button at the end of the field to choose from access devices on Trunk / Access Gateways or access devices on Subscriber Gateways. Then select from the displayed list of gateways of the specified type. As a short-cut to select the gateway, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. If the task you are using has already added access hardware and is now adding a new subscriber to use this hardware, this field is read-only. |
Access Device | The Access Device that this line uses to connect to the NE. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. Click on the search button at the end of the field to choose from Access Devices on the gateway specified in the Gateway field. If the gateway contains only one Access Device, this device is selected automatically and there is no need to change it. As a short-cut to select the Access Device, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. If the task you are using has already added access hardware and is now adding a new subscriber to use this hardware, this field is read-only. |
First Access Line number | This field appears only if Call Agent signaling type is set to Analog line/T1 CAS.
Select the Access Line number on the specified Access Device to be used for the first subscriber; the remaining subscribers will be given consecutive lines on the same access device. Either type in the number (which must not match the access line number used by any other subscriber on this access device), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use.
The highest line number that you can specify depends on the access device type: for an IAD it is the number of voice ports configured, and for other devices it is a configured parameter on the access device.
If you click on the ellipsis symbol, the dialog box that appears offers 'manual selection' or 'automatic selection'.
|
ISDN Interface | This field is not applicable if you are configuring connection information for Business Group Lines. This field is valid only in the US. |
Use DN for identification | This field is not applicable if you are configuring connection information for PBX Lines. Specifies whether the subscriber registers using their directory number instead of a textual user name. This field appears only if Call Agent signaling type is set to SIP and Number status is set to Normal, Ported to, or Non-geographic. When this field is set to False, the SIP user name prefix is mandatory. When this field is set to True, the SIP user name prefix field is hidden. |
SIP user name prefix | This field is not applicable if you are configuring connection information for PBX Lines. This field appears only if Call Agent signaling type is set to SIP and Use DN for identification is not set to True. It is mandatory if Use DN for identification is set to False. A prefix to be used for SIP user names. The first character must be a letter (either uppercase or lowercase). Each subscriber will be given a user name starting with this prefix, followed by a number starting at 1 to distinguish between them. This field represents the user part of the SIP URI, not including the prefix or domain name. None of the names generated using this prefix can match any other SIP user name with the same domain name. |
SIP domain name | This field is not applicable if you are configuring connection information for PBX Lines. The SIP subscriber's domain name. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP and Number status is set to Normal, Ported to, or Non-geographic. Set this field to match the domain name configured on the SIP device; typically this is a DNS hostname that resolves to the MetaSwitch NE's virtual IP address, or the IP address of a Session Border Controller through which the device accesses the NE. |
Media Gateway Model | This field is not applicable if you are configuring connection information for PBX Lines. The Media Gateway Model used by this subscriber. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP and Number status is set to Normal, Ported to, or Non-geographic. Choose Use default or select from the displayed list of SIP Media Gateway Models. To indicate that the Media Gateway Model should be selected by matching against the SIP User Agent string provided when the SIP device registers with the MetaSwitch NE, select Derived from SIP User Agent from the list. If you change the Media Gateway Model for a subscriber who is already in a call, this call continues using the existing model. The new model is used from the start of the subscriber's next call. |
SIP authentication required | This field is not applicable if you are configuring connection information for PBX Lines. Specifies whether this subscriber uses SIP authentication (and must supply authentication parameters in SIP signaling messages). This field appears, and must be supplied, only if Call Agent signaling type is set to SIP. If you are adding new subscribers or enabling SIP authentication for existing subscribers, you must also specify an initial password for the subscribers in the New SIP password and Confirm new SIP password fields. You can then update the subscribers separately to provide individual passwords for each one. |
New SIP password | This field is not applicable if you are configuring connection information for PBX Lines. The password that this subscriber uses with his or her SIP phone to register. The password is not displayed in the EMS and you cannot view it, although you can change it to a new value if necessary. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP. If you are updating existing subscribers who already use SIP authentication, leave this field unchanged. Otherwise, specify a text string of 6 - 15 characters. This is used as an initial password for the subscribers; you can then update the subscribers separately to provide individual passwords for each one. |
Confirm new SIP password | This field is not applicable if you are configuring connection information for PBX Lines. This field appears, and must be supplied, only if Call Agent signaling type is set to SIP. To confirm that you have typed the new password correctly, type it again in this field. The characters you type must exactly match the characters you typed in the New SIP password field. |
Preferred location of Trunk Gateway | This field appears only if Call Agent signaling type is set to SIP. 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 on the switch). Select from the displayed list of available Location objects or None (no location). |
Number of subscribers | Specify the number of subscribers to be added. The maximum number of subscribers you can add depends on the access lines available on the access device you have selected; there must be a continuous range of free lines available.
For example, if you select port 3 on a device that has 8 ports and no other ports on this device are in use, you will be able to add a maximum of 6 subscribers (on ports 3 - 8). However, if you select port 3 and port 6 is already in use, you will be able to add only 3 subscribers (on ports 3 - 5).
If you are adding Business Group Lines, the maximum number of subscribers is also limited by the number of free directory numbers in the parent Business Group Number Block, in the same way as for the free lines on the access device. |
