Payload Separation
If an XPhone user in the home office is connected to the company via a VPN connection and uses Softphone Desktop, it may make sense that the media data (audio stream) is not sent via the VPN connection but via the Internet. This can be achieved with payload separation.
Requirements
To enable a path for the audio media outside the VPN tunnel, the following requirements must be met:
The host of the VPN client must also be able to reach the Internet directly.
The XCC and the corresponding SIP gateway must be configured for external media and accessible (WebRTC).
Configuration
Since you want the media candidate, which goes through the VPN tunnel, to no longer be used, you have to enter the following under System settings > Telephony & Meetings > Telephony > SIP > XCC
…the IP address (ACL) for the VPN network is removed from the Private IP address ranges list.
…the remote IP address (ACL rule) must be added to the Access control via IP address areas (blacklist) list.
If there are several IP address ranges that are to be suppressed in any case, these can also be added.
