This page contains instructions on how to provision a Phone terminal extension.
By using VoipNow's provisioning feature you can set and maintain identical configurations for a large number of equipment. SIP devices associated with a Phone Terminal extension can be automatically configured using either customized provisioning templates added by the extension's parent accounts or the default configuration files, specific to each device model.
At extension level, in order to configure the required device, the Phone terminal account owner is only allowed to use the default provisioning template.
After you have successfully added your Phone Terminal extension, VoipNow displays the following message:
Clicking the first link will redirect you to the SIP Devices page, where you can add a new SIP device or assign the extension to the devices from the SIP Devices Inventory table.
If you click the second link, you will be redirected to the extension's management page. Click on the SIP Preferences icon under the Telephony area and you will be able to customize the SIP options for your extension and/or enable the Extension virtualization feature.
The account owners that log in to the VoipNow interface using a service provider, organization or user have complete access to the SIP Preferences page only if the Phone extension SIP management permission is enabled.
The Phone extension SIP management permission can be enabled from the Roles and Phone Numbers for <account_type> <account_name> page, when the account is created.
If this permission is disabled, then the user of the Phone terminal extension will only be able to see the Equipment description details in the SIP Preferences page. The rest of the SIP settings will not be displayed.
This option allows media (voice or video calls) to be encrypted.
VoipNow supports the following crypto standards: SDES and DTLS-SRTP. SDES is a crypto standard we use for voice and video calls over mobile networks. DTLS-SRTP is a crypto standard we use for voice and video calls through WebRTC.
From the drop-down list, you can choose among the following options: SDES, DTLS-SRTP, SDES/DTLS-SRTP (and/or). By default, this option is set to None.
If you want to use any of these crypto standards, you must first ensure that your client (IP phone or softphone) supports it. If the crypto standard you have selected is not supported by your client, calls will not work.
Choose the DTMF mode. Default: rfc2833.
|A PBX is connected to this extension
This option allows the system to direct an incoming call made to a public phone number to a particular extension on the PBX server connected to the extension for which the current setting is enabled.
To make it available, setup the Maximum public concurrent calls to a limited number (now it is unlimited).
Ping the extension to check its status
When enabled, the server sends ping SIP messages to the extension regularly. Usually, this option is used for extensions behind NAT.
|Allow re-invites from this extension
|If enabled, your extension will be allowed to send re-INVITES.
Extension is on private network (<ip_address>/<network_mask>)
This option is available only if you choose the NAT (Network Address Translation) or Public/Private Networks Routing infrastructure types from Cloud Management → Infrastructure Properties.
Extension publishes its own state
Enable this option if you do not want the server to send presence notifications to the phones watching this extension for presence.
Force enable of MWI
Enable this option if you want to receive Message Waiting Indicator notifications and your phone does not send explicit subscriptions for MWI. Most phones do not need this option.
Select the codecs supported by the phone device.
Phone does not register, is located on IP <> Port <> and <has to/does not have to> authenticate
All incoming calls from this IP/Port require/do not require authentication.
The drop-down list is disabled until an IP address is filled in.
|SIP Signaling Transport
Select the network protocol used on channels: UDP or TCP. Available for extensions that do not register, located on a fixed IP. Default: UDP.
The drop-down list is disabled until an IP address is filled in the Phone does not register, is located on IP field.
Allow extension SIP connection only from IP <IP_address> (maximum class C (/24)
Limit the extension usage to an IP or a network. Only the IP addresses specified here will be allowed to receive and make calls from this extension.
|Briefly describe your device.
Allow virtualization on this extension: If enabled, any other member of the organization can use the phone device where the extension is provisioned. By default, it is unchecked.
