VIVOTEK vs8401 - two way audio

[Nacho]

Hi! I'm developing an interface in C# and I need to implement a Two-way audio communication with my VS8401 video server. I've been reading about and the video server uses SIP protocol for two-way audio comm. So anyone knows how establish a call with the video server using SIP, which one is the SIP account and how to specify the channel to talk with.
Or do you know using RTSP or other protocol how to send audio from my pc to the vs?

Thank you.

Hi Nacho,

This is the basic mechanism to explain how the stream works.
Down stream (Camera -> Client): RTSP (signaling) + RTP (media)
Up stream (Client -> Camera): SIP (signaling) + RTP (media)

If you drop me an email to info(at)use-ip.co.uk I can share with you a more detailed internal document which may help.
