Support for VoIP phones
When you install Citrix Gateway as a standalone appliance and users connect with the Citrix Secure Access agent, Citrix Gateway supports two-way communication with Voice over IP (VoIP) softphones.
Citrix Gateway supports the following VoIP softphones.
- Cisco Softphone
- Avaya IP Softphone
Secure tunneling is supported between the IP PBX and the softphone software running on the user device. To enable the VoIP traffic to traverse the secure tunnel, you must install the Citrix Secure Access agent and one of the supported softphones on the same user device. When the VoIP traffic is sent over the secure tunnel, the following softphone features are supported:
- Outgoing calls that are placed from the IP softphone
- Incoming calls that are placed to the IP softphone
- Bidirectional voice traffic
Support for VoIP softphones is configured by using intranet IP addresses. You must configure an intranet IP address for each user. If you are using Cisco Softphone Communication, after configuring the intranet IP address and binding it to a user, no additional configuration is required. For more information about configuring an intranet IP address, see Configuring Address Pools.
If you enable split tunneling, create an intranet application and specify the Avaya Softphone application. In addition, you must enable transparent interception.
