Devices provide a connection between a physical IP phone (e.g. your desk phone, computer, smartphone, etc.), the phone system, and associated calling features. Devices can also act as endpoints for a call routing path. For example, a phone number can be routed to a device, or a device can be part of a ring group. Users can also place phone calls from their devices to internal and external endpoints. In the simplest case, a device ties a physical IP endpoint to a logical endpoint on your phone system.
Additional features available for devices include a timeout and failover destination, unique Caller ID, and a specific Access Control List.
- Physical device configuration: SIP devices vary greatly by manufacturer. As long as the device is SIP-compliant you can configure it with the Login and Password for the device to register to the associated instance. If you aren't sure how to configure your device, please consult technical support or the device manufacturer.
- Call Parking: Access call parking by pressing '*9' (Star-9) while on active call. The system will place the caller on hold, read back an extension number between 1000-1999, and hang up your end of the call. The caller is now parked on an extension with hold music until retrieved by dialing '*9' (Star-9) while not on a call and entering the extension of the parked caller. Parked calls cannot be picked up on a different site than they were parked on. Call parking cannot be accessed on inbound calls that traversed a ring group.
- Dialing rules: When calling the US/Zone 1 it is not necessary to enter a 1 before the number. Calling international requires a 011 or + to be sent before the number. Calls sent to a device will be sent with the username in the SIP INVITE.
- Allowed Codecs: PCMU (G.711u), PCMA (G.711a), G.722, and GSM which are all recommended at 20 ms ptime.
- Name Column: The name of the device is listed in this column (e.g. 'Test Device 1'). You can select/click on a respective device's name. This action will redirect you to the specific device's edit form.
- Login Column: This column lists the 'Login' information associated with each device record within the device column.
- Caller ID name Column:
- Edit Column: This column includes the edit icon. Each edit icon in this column is associated with a device record. When you select/click on an edit icon for a specific device, you will be redirected to the edit form of the respective device record.
- Delete Column: This column includes the delete icon. Each delete icon in this column is associated with a device record. When you select/click on an edit icon for a specific device, a dialog box appears requesting you to confirm the delete request. There are two options available within the dialog box: the 'cancel' button and the 'delete' button. Selecting the 'cancel' button terminates the delete request. Selecting the 'delete' button processes the delete request and permanently removes the device from the device table and from the instance.
- Origins Column: This column contains all of the origins icons. When you select/click an origin icon that is associated with a specific device, you able to view and modify all the features that route to the specific device
- Routing Column: This column contains the routing icons. When you select a routing icon that is associated with a specific device record, a graphical dial plan
There are two primary methods to access a device edit form:
- Option One: You can select/click on the device's name (located in the 'Name' column within the Devices table).
- Option Two: You can select/click on the edit icon () associated with the respective device you area wanting to edit/update.
Edit Device Form and New Device Form Components
The following are components of the add device form and edit device form:
- Name: The name used to identify the device and how to distinguish this device from all other device records within the device table.
- Login: A login is between 4-32 characters for SIP registration and authentication
- Password: A password is displayed/autofilled in the device edit form. Above the 'Password' field is the 'Regenerate Password' option/button. When you select/click on the 'Regenerate Password' option, a new password is displayed in the 'Password' section of the device form.
- Channel Limit: Devices can have between 1 and 25 channels. A channel is a "line" that your phone uses to place or receive a call. Typically, one call requires one channel.
- Timeout: The duration of a timeout can be set to anywhere between 1-120 seconds. A timeout specifies how long the device will ring before transferring the caller to a specified failover destination or hanging up the call.
- Failover drop down menu: Specifies where callers will be directed if the device does not answer within the timeout period. This can be any other routable destination such as a menu or voice mail box. If no failover is assigned to the device (and the failover drop down menu is set to '------'), callers will be disconnected once once the timeout duration is reached.
- Caller ID Name: Enter a specific name to be set and displayed on outbound calls.
- Caller ID Number: Enter a specific number to be set and displayed on outbound calls.
- Access Control List (ACL): This field specifies IPv4 address(es) or CIDR-notated subnets that override the default instance ACL. If this is not set, it is inherited from the instance ACL.
- Location Drop Down Menu:
- Timezone Drop Down Menu: Select the correct timezone from the dropdown menu (e.g. 'US/Eastern'). Selecting a timezone is optional.
- MAC Address: Enter the MAC (Media Access Control) address associated with the device. Entering the MAC address is also optional.
