dahua VTO VTH work with FreePBX SIP server and GrandStream GXV3380 SIP phone 

Can use only VTH as indoor Video Intercom set for apartment use of Hikvision/Other model which will use under existing IP-PBX for sip video conversation with any other SIP Video phone?

Excellent video!! Still can´t figure why you add a free pbx server while you can use just your 6541 VTO as a standalone server

Hi, can you show the configuration in the GXV3380 to enable video as soon as the VTO is pressed, and how to unlock the VTO door or relay?

Hi, congratulations on all the videos that you have on your account. However I would like to buy a intercom kit with LCD from Dahua VTO, but I don't know which model to choose. I would like to have only 1 button from outside and the possibility to integrate with homeassistant or different iot platforms.

Thanks for the demo. Please i have a problem: I need to connect the Villa Outdoor station Dahua model: DHI-VT02311R-WP wich is connected to the same LAN as FreePBX. Is it possible to connect this model as a standalone device to FreePBX or do I need also indoor Dahua Grandstream or some other device as a server. Can this model VT02311R-WP work direct with the FreePBX? Thanks

Hi! Good work! How can I see configs from Your FreePBX? Is it works on sip or pjsip?

In my opinion this is not well configured. There is no video preview in any of the devices when the door station makes a call. Can you make a video how you configure video preview? thanks.

Hello, how do you open the vto lock through grandstream phone?

Any android softphone app to add to this puzzle?

How to unlock VTO station? Can you show it ?

Good day!!! Please tell me what program is on the smartphone
