Typo... the last line should be if I set 'bridge_early_media, then all devices will accept the video however, the video is simply a blank screen with *no* content- basically a black screen On 12/27/2022 1:58 PM, Jerry Kendall wrote:
Hi Antony,
Yes, it does work with one device in the ring grouop.
In fact, if I toogle or change the devices within a ring group it works regardless of which device - as long as it's only one device in the ring group. Once there are more than a single device, the the video preview only works on the first device to reply with a '183 progress...' All the other devices get a cancel as FS gets the 183 and cancels all other devices... even if they send a '183 progres...'
if I set 'bridge_early_media, then all devices will accept the video however, the video is simply a blank screen with on content

Does anyone have experience with ring groups that show a preview (on all video capable phones) of a door phone? I somehow doubt that it is possible to send a preview to a ring group.
That's verging on video-conferencing, after all.
I have Fanvil (V67/I53W) and Grandstream video phones (GXV3480/GXV3240) connected to Fanvil(I64) and Axis(A8207) door phones.
the door phones are able to send preview and the phones are able to receive previdw but the screens only show a black image - no live video. Have you tried reducing the configuration to a simple setup of one door phone and one video phone, to see whether a preview can be sent/received like that?
If that works, do a packet capture and look at the SDP part of the SIP communication, and then compare with the same thing using a ring group.
Antony.
