Yes, if the video call is made On-Net. Audio will be proxied thru the switch but the video is peer to peer.

Typically, video calls will NOT work thru the PSTN because many carriers will reject the call if video codec is found in the SDP body. For this reason, we use best effort to strip these codecs before leaving our Network towards the PSTN. Most failures related to enabled video codecs are observed when calling toll free numbers.

Keep in mind that video calls require a significant amount of Bandwidth on both sides of the call. If the intent is to use Video calling outside of the LAN, make sure they have the bandwidth requirements to support it.

Note: When configuring video phones, be mindful about the amount of Video Codecs enabled. Having too many video codecs enabled may cause call setup issues with other phones or devices.
