Video preview cannot work in Leelen devices

[Grace Liu]

Good day everyone,

The Leelen intercom device and Leelen indoor device both remotely manually register to the 3CX server. When the intercom device makes a call to the indoor device, the indoor device starts ringing, but it does not display the preview video from the intercom device.

We make a capture in 3CX server, can someone help investigate the cause, please?


Thanks
Regards
Grace

Early Media is not supported in 3CX. Try having the intercom dial the other one directly (like via Direct IP Call.)

Do you mean we need to make sure that video preview can work with direct ip call firstly, after that we will test it with 3CX server, right?

Yes

When the intercom device dials the indoor device with direct ip call, there is the video preview, and the call is like this:


Can we know why the 3CX server replies with a 180 message to the intercom device so early? or what is the next step we can do?


Thanks
