cant receive video when VVX Camera disconnected

cant receive video when VVX Camera disconnected

software tested:   UC 5.7.0, 5.6.1 and 5.6.0
Models tested on:VVX500,  vvx501, vvx601
connection:  OpenSIP

hoping for some help, my VVX phones will only display a Black Screen when a video call comes in if there is no VVX Camera attached.

relevant settings:

 

    video.enable="1”
    video.allowWithSource="0"


I see both sides send video SDP, negotiate, etc.   but if i do not have a VVX Camera attached to the phone, i just see Black and not the incoming video.


the exact same configuration, with the Exact same codec negotiations, with a VVX Camera attached, successfully gives me 2 way video.

removing the Camera re-introduces this issue.

since it Works with the device attached, and the codecs do not change in the network, i am leaning towards this being a Polycom issue.

End goal:
to have specific VVX501/601's set up to receive video from a door phone, with one-way-video, for admin staff to be able to allow users through a locked door after verifying safety/identity.

I have tested this as:
Polycom (camera) to polycom (no camera)
Algo 8039 to Polycom (camera)
Algo 8039 to Polycom (no camera)
Broadworks Desktop client to Polycom (camera)
Broadworks desktop client to polycom (no camera)
and on each, if there is no camera attached, the screen displays blank video.  if there is a camera attached (even if its on video mute),   video is correctly displayed.

Hello @Stephen_Holinaty,

welcome back to the Polycom Community.

Have a look => here <= as we do support to receive a Video Call on a Device that supports a Camera but has none attached.

Re: cant receive video when VVX Camera disconnected

Thanks Steffen,  I had read through that post in its entirety prior to making this new query.

From reading it, it seems the Polycom response is "it should work" and the community response is "but it doesnt.."

What I am seeing is, if the ONLY change is the addition or removal of the physical camera, with no change to the signalling, the VVX phone will:

Both bring up the video screens, as though the Polycom VVX phone is receiving video
however, ONLY if a physical camera attached does that video feed actually work.  if there is no physical camera, my test results have been "solid black screen".

From a wireshark capture, the VVX phone is receiving the video packets, but not actually displaying them.

Would my best way forward be to create a reseller/partner ticket?

Hello @Stephen_Holinaty,

Yes the next step is a Ticket via your reseller. As you can see in the old post the original poster never came back.

Re: cant receive video when VVX Camera disconnected

Your service provider may be anchoring audio/video on their Session Border Controller.  If they are using an SBC, and are anchoring RTP, then you will not receive video from them as your phone does not sent out a video stream when a camera is disconnected from it.

 

The SBC will send your phone video only when your phone sends video first.  Most customers have firewall, so the SBC has to learn how to send video back to the Firewall, which then forwards it back to your phone.
