1.4 Network handling, Device handling and Integration

Network handling

Under Network handling, you have the following options:

Disable T.38 for fax

Activates/deactivates to globally disable the T.38 fax protocol for all inbound and outbound calls, including the eFax service. Faxes will be transmitted using G.711 (audio) only.
Only available for A accounts.

Alternative SIP port

Activates/deactivates using a non-default port setting for SIP, which can help avoid firewall problems.
Only available for A, C and S accounts.

SIP transport protocol

Allows defining over which transport protocol devices/apps on this site communicate.
By default, it is set to UDP (User Datagram Protocol), which means that the calls are not encrypted. 
TLS (Transport Layer Security) ensures that all calls made from certified devices that support SRTP (Secure Real-time Transport Protocol) will be encrypted.
TCP is only available for A accounts or is visible when it has already been set by the A account.

Please note that in most cases, TLS is a chargeable feature charged per device.

Please note that if this setting is reset, all end-user certified devices will reboot.

 

Provision site VLAN settings

Activates/deactivates the connection of deskphones to a business VLAN network.

Device handling

Under Device handling, you have the following options:

Password-protect phone web interface

Security feature for desktop phones which activates/deactivates protection of the configuration set up during provisioning. Password protection will prevent changes made by end users, which may disable the device or impact required settings.
We recommend having this feature activated at all times.

Disable PC / data port

‌Locks the PC / data port at the back of the phone, so that the built-in switch bridge is disabled.

By default, this option is disabled.

When enabled, end users won't be able to use the phone as a network bridge to connect their computer to the network.

When disabled, end users will be able to use the phone as a network bridge to connect their computer to the network.

Softphone device creation password

When you first install a softphone, you are required to enter this password during the setup process to authorise the installation. You have to change this password, as the default password is unknown.

Integration

Under Integration, you can see whether CTI is activated or deactivated on the tenant (read-only). To enable it on a target, this setting must be configured later under Extensions.
