This step is mandatory if the Number status field in the previous step is set to Normal, Ported to, or Non-geographic. Otherwise there are no 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:
|
Access Device | The Access Device that this subscriber uses to connect to the NE. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. 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. Click on the ellipsis symbol at the end of the field to choose whether this device is on a Trunk/Access Gateway or on a Subscriber Gateway. Then choose the gateway, and finally the access device. |
Access Line number | The Access Line number on the specified Access Device that this subscriber uses. This field appears only if Call Agent signaling type is set to Analog line/T1 CAS. 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 appears only if the Call Agent signaling type field is set to ISDN PRI; it is not valid for a Business Group Line. |
Use DN for identification | 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.
If this field is set to True, the SIP user name field will be hidden. If you change the value of this field and SIP authentication required is True, you must reenter the value in the New SIP password and Confirm new SIP password fields.
Values:
|
SIP user name | The SIP subscriber's user 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, and the Use DN for identification field is set to False. . Set this field to the user part of the SIP URI, not including the prefix or domain name. This is a string of 1 - 32 characters, which must not match any other SIP user name with the same domain name; the first character must be a letter (either uppercase or lowercase). |
SIP domain name | 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 | 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 | 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 enable SIP authentication for an existing subscriber, you must also specify the SIP user's password in the New SIP password and Confirm new SIP password fields. Either ask for the user's preferred password, or specify a new password and provide it to the user for future use. |
New SIP password | 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. Specify a text string of 6 - 15 characters. |
Confirm new SIP password | 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 locally). Select from the displayed list of available Location objects or None (no location). |
