Verba Proxy Recorder service consists of the following modules:
- Remote Capture - This module allows to remotely capture network traffic. When the service is enabled on a server, Verba Recording Servers - deployed on other servers - can get access to the network traffic of the local network interfaces on the server. The application is primarily used in Microsoft Lync recording, where the remote capture service is able to identify the recorded call related streams and send them to the Recording Server for processing. The remote capture service receives signaling information for the Lync Filter applications, installed on Front End servers and SBAs and SBS. Signaling information is used to identify the relevant streams and only fork streams related to recorded interactions.
- RTP Proxy - This module acts as a standard RTP proxy, allowing to reroute any RTP stream through the application and provide access to media streams for recording. You can use the RTP proxy in any standard SIP environment together with SIP Proxy module, and in Lync environment together with Lync Filter applications installed on frontends, SBA and SBSs.
- SIP Proxy - It is a standard bypass SIP proxy server implementation. You can reroute SIP calls through the proxy server in order to get access to media streams for recording, and insert into the calls the RTP proxy module. The proxy server can act as SIP outbound proxy and as SIP router, in this case calls based on called pattern are rerouted to intended next hop in the route. The proxy supports TLS so secure SIP and SRTP in the RTP proxy is supported as well.
You can use any of these modules in the service, you can also combine them on a single server.
