Hello, since some days i am trying to setup my Asterisk Server on an Debian machine for my IP-VideoDoorbell Dahua VTO2000. As Clients i am using only Android SIP Clients (Linphone).
I have fixed to work almost everything except the possibility, to show me a Picture in my SIP Client before i accept the Call from my door.
With the following command i managed to take a picture when someone ring the door.
But how can i attach the taken picture to the call to my Linphone Client?
Also before i accept the Call from the door, i would like to see who is at the door.
I hope you guys can help me.
Thank you in advance!
It is like some kind of early media but instead of playing audio displaying a picture. I dont think you can transfer a picture if the SIP session has not been established previously. You could transfer the picture outside SIP session, and open it in separate software and after that decide if answer or not the call
I am using a different door bell and have solved this differently. Instead of playing too much with the Asterisk config, I am using vlc to see what’s going on whenever I want to.
Playing with same device since a while on an asterisk 16.2.1 (chan_sip).
In fact, the device is able to send early media when requested by the destination with “101 Dialog Establishment”. My problem, asterisk does not forward the messages to VTO2000A:

I also thinked about that. That would be the alternative, to send an push to my Telegram Account.
But i thinked maybe it could be possible to see the picture directly in my SIP Client.

It would be very nice, if you will find an solution for this
Unfortunately i am a noob in such things
After reconfig of the devices, asterisk receives “180 Ringing/SDP” from destination and sends correctly “183 Session Progress/SDP” to the doorphone. This leads to early media (acc. RFC3960) and video stream get’s shown on indoor display.
