Loxone Intercom Woes - SIP stops working and needs reboot?

[Simon Still]

The Loxone intercom has given me more issues over the last 5 years than any other internet connected device.

Various things before where the video would stay up but it would lose the connection to Loxone (so no bell/notification). That's stopped which is good. 

But current issue is that the SIP connection seems to stop working after a while. The video is still up, it's connected to Loxone (rings the bell/notification in the app) and I can trigger the 'open gate' command.  

Internal to my network I get  'Busy. Please try again later'  and externally

 'Audio connection failed' The extension is not available (with my sip:****@sip.antisip.com)  (404)

Pretty sure last time the SIP stopped working I could connect over IP to reboot it but today it was refusing a web browser connection too.

A reboot solves it. for a while.

I don't get it. The video is obviously completely separate module.  And that is maintaining a connection to my network, and passing the video through to the open internet.  The SIP module (which controls everything else) must still have a connection to my network as its' linking to Loxone.  But it's losing some functionality.

Any suggestions?

This is the kludge of course...create a way of remote power cycling the intercom.  Doesn't diagnose the problem, but deals with it, possibly manually.

Although it's run off my PoE switch, which also runs a load of other devices that DONT like being power cycled.

Here are some ideas or suggestions I can think of.

1. Your router might be dodgy, can you swap it out for another to see if this causes the problem.

2. Is your firmware upto date, I noticed on the Intercom documentation on the Loxone website there is a link to a firmware update.

3. What is your cable distance from the router to the intercom.

4. Looking at the intercom, that network connection on the back to me looks prone to interference, no shielding or anything.

Don't know if any of this will help, but you never know.

It's a TPLink Archer VR600. They have a good rep and I need the port forwarding it has for the intercom! My ISP's supplied router didn't work...

yes, appears to be.

Remember, the video is still working, and the button is still signalling Loxone,  so there is still an useful network connection when it's NOT working on SIP

Yes, the circuitboard is worryingly exposed on the back for something that is 'external'.  but I've never found any evidence of damp when I've taken it off over the years.
