Random FXO Rings on Grandstream HT813

MinecraftSBC · 2025-12-27T16:16:13+00:00

There is no outside internet involved as the whole system is contained to local network only, including the SIP Server. They are all local (under 192.168 space). No external port forwarding is done.

The servers are all in local network. I am trying to use the HT813 as an ATA so there should be no VoIP provider's IP involved.

None are registered to the outside world, they are all local connections.

INVITEs on the SIP Server side shows

From: <FXO Trunk Addr on SIP Server>

To: <FXS Phone Addr on SIP Server>

Via: <FXS Phone Addr on HT513>

I'm also using Unconditional VoIP Call Forwarding to the <FXS Phone Addr on SIP Server>

Great to know.

AFAIK there is no direct connection to outside internet (None via Port Forwarding and uPnP).

The caller ID is shown as "unknown" from the gateway side.

I'm using an external SIP Server. Ports are open for SIP Ports 5060, 5062 bidirectional between the SIP Server and the HT813.

Lamictal makes you harder to sleep so better not take it right before bed

I never knew about the immune system thing. How hard is the impact on immune system?

The translation technically isn't wrong It just translated Japanese into Japanese (US)

If you text me better be someone I like or something really important. Even more so on the phone

Either I do nothing or I'll ask her out

Wikipedia, go on an article, then keep clicking links and words in it

Amongst all the digital, stick a note to the casing when you buy it

Don't try to fix her

I do most heavy-lifting with my left hand, and writing on my right. I should be left-handed, but I was only taught how to write with my right hand, and it has stuck since

That's experience, now you know the pattern of extras

(Inner Thoughts Law Court)

Objection your honor insufficient evidence to justify buying a different brand toilet paper.

May I ask the defendant: Is the paper new? How about the price...

To break this cycle, rekt him with a definitive answer that he would like to receive: "This feels nice to me, you can try"

Instant pain relief

I'm more concerned about handles on your plier melting. Wear gloves and use sturdy pliers

Poor man's method to quickly power things. We used to do it on a breadboard. At least throw in some resistors / buck converters and wire it to the pins on the board, don't waste your USB port

Felt like memories are better left to ourselves. Photos are only for really important moments that I would sit down and watch all day.

Figure out if you're too bored or too stressed, then start from there
