  1. This sounds for me like a SIP issue. To get video before picking up the call, the destination (VTH) has to send a 183 SESSION PROGRESS + SDP message to the caller. This is called early media. Obviously the VTH is able to do this, the other phones not (or at least not out of the box). I'm working on this issue since a while. I do not have VTH, only VTO and 3rd-pty phones. It would be very, very helpful to get a SIP/LAN trace of both, the good and the bad case. Then I might be able to figure out how to get asterisk to act like the VHT.
  2. Anybody who would share his configuration export of a VTO2000A running 201801 SIP firmware? I wanna compare it with the old config (SIP 201704). I guess I might figure out what new features have been implemented by DAHUA.
  3. In fact yes, if you are experienced enough to modify the firmware with the toolset mentioned above (BotoX/Dahua-Firmware-Mod-Kit). I dunno the changes of V3.3, but I guess everything of your setup should work with 201704 too. I have a similar setup like you, but my phone is a GXV3140 and server is asterisk. By lowering the video resolution for voip calls (not the rtsp stream!), I got it working just like you. To have video in the phones displayed before actually answering the call, you need to activate a SIP function called early media. Currently I am working on this issue as well.
  4. Since a few days there is a brand new SIP fw out:ftp://ftp.asm.cz/Dahua/videovratni/VTO2000A,VTO2000A-C/firmware/SIP_20180105/General_VTOXXX_Eng_P_16M_SIP_V3.300.0000001.0.R.20180105.bin No info regarding changes so far (as usual). Any testers arround?
  5. While checking the config.export, I found the parameter "SIPServerRedundancy:x.x.x.x" and some corresponding variables at the very end of the file: SIPServerRedundancy:192.168.1.39, UserEnable:true UserID:19 UserType:0} Web:{Enable:true,Port:80} DialRule:{BuildingModeEnable:false DiaSeperator:# ExtentionModeEnable:true UnitModeEnable:false} ... SIPKeepAlive:{FailTimes:3,KeepAliveTime:60,SipServerEnable:true}} It looks like the VTO2000A might be able to handle a redundant SIP server as soon as the keepalive mechanism detects a fault. At least DAHUA tried to implement something like this. I put the IP of my backup asterisk there, but so far it don't want to register there (main server disable, off course). It would make sense for a security device like a doorbell to have such feature.
  6. I guess I found the solution by myself! I found out, that the file that gets created with "Export Config" is a simple textfile. After analyzing it, the parameters regarding the "TalkbackDevice" seemd to me to have something to do with the SIP settings. "TalkbackDevice": {"AudioChannel":0,"AudioEnable":true,"AudioStream":"Main","VideoChannel":0,"VideoEnable":true,"VideoStream":"Main"}, So I changed the VideoStream for TalkBackDevice from "Main" to "Extra1" and uploaded the config again. The "AudioStream" parameters changed itself then to "Extra1". And now I get a resolution of 320x240 in SIP video calls. It really seems that did the trick! Maybe this is helpful for other issues regarding video as well - just edit the config manually.
  7. Did you have a look at this: https://www.ip-phone-forum.de/threads/im-dialplan-per-script-ein-snapshot-erzeugen-f%C3%BCr-die-fritzbox-t%C3%BCrsprechanlage.288096/#post-2185372 I just did wiring of the 24V via wires 4/5 and 7/8 by myself. I pulled out the power wires and then I crimped a RJ45 at the remaining ethernet wires (1/2+3/6). Do you know the HTTP API for Dahua devices: https://support.amcrest.com/hc/en-us/articles/232310368-HTTP-API-SDK-for-Amcrest-products This might help you.
  8. For sip video calls I got a used Grandstream GXV3140 phone. It supports h.264 codec, but unfortunately I am not able to get it working fine with my VTO2000A. Call setup is ok, audio is good, but video is shown as a "grey pixel soup". I guess, the phone can't handle VTO's "high-res" h264 video (800x480) from main profile. I expect also, VTO's extra format when set to QVGA (320x24) might work on my phone. Any Idea, where I might be able to set the used video profile for SIP calls to "extra"?
  9. Yes, but this should not be a problem. The SIP FW comes officially from dahua. Yes, this should work. A long as the phone supports h.264 codec (like GXV3240 does), you do not have to transcode it. Yes - I do it as well. No - it needs 12-24V DC, which can off course be delivered via the spare wires of a CAT5/6/7 cable like many other "cheap" devices do.
  10. Hi! Is there anyone out there, who still has a old SIP firmware, where telnet is still included? I would extract this one and check the difference to newer ones - then I am able to help.
  11. Off course. Just connect it to your wifi and install/configure a sip client app. I prefer BriaMobile ($$), but there are some good ones for free (e.g. zoiper).
  12. I guess the reason is: you have a VTO2000A(1mp) and not a VTO2000A-C (1.3mp, modular). According to a datasheet I found, this seems to be different.
  13. I managed to replace all sound files in the actual SIP firmware (20170425) and installed my VTO2000A finaly at my house' door. I receive emails with pics when someone rings the door and added the cam in my synology's surveillance station. Off course my physical phones ring with a special sound (distinctive ringing) while my soft phones (windows/android) show video too. Nice goody from a russian site: when I get a visitor while I watch TV, my linux based satellite-receiver switches the channel to my VTO's cam automatically. I am very happy with it so far. There is only thing I was not able to figure out so far: How does the sabotage contact work? Is it just this noisy sound outside my door, or does anything happen on the network too (FTP-Upload, SIP-call,...)?
  14. What app do you use on the mobile phones to get video? So far I only had success with BriaMobile($). Where do you register the Mobile phones - asterisk or fritzbox?
