OK, so I've got the StrongSwan IPSEC tunnel to connect by moving to Ubuntu.

But I still can't ping the VoIP endpoints (same as with the Python IPSEC), so I assume this is network filtering on the O2/GiffGaff side.

Will fire up the Asterisk port at the weekend and see if I can make a call (might also try my EE SIM)

What do the #VoIP experts think of the #Nintendo Gamechat announcement? It looks too good to be true. My experience with voice and video calls hasn’t been great, and that’s with software written by companies dedicated to this field, even sometimes with expensive specialized hardware. I haven’t seen anything that works well without a headset, and even with one there are still issues.

Reticulum
Wouldn't it be nice if you could have a real telephone, that wasn't wiretapped by default?

Encrypted, decentralized and truly peer-to-peer voice calls and telephony over Reticulum is now a reality with the newly released LXST framework. Because it uses Reticulum for data transport, LXST voice calls require no intermediary servers or accounts anywhere. Anyone with an LXST-enabled device or software client can call anyone else - as long as there is a network connection between the devices.

Using the efficient hybrid mesh routing of Reticulum, this also means that your calls aren't routed anywhere they shouldn't be. If you call an endpoint in the same building, the telephones connect directly, and not over somebody elses VoIP server in another country.



These two prototypes are fully functional telephones, that can dial to and receive calls from any other LXST endpoint. It takes about 20 minutes to assemble one, and it's built from completely standard and readily available components, obtainable from common electronics vendors.

Initial client support is already implement in the Sideband application for desktop, the command line application rnphone, and of course the physical telephone implementation.

Like other Reticulum-based protocols, authentication and encryption is handled by the self-sovereign identity layer in Reticulum. This means that you truly own your addresses, and that you can move around to anywhere in the network (or another network altogether) and still be reachable for anyone else. If you have an LXST "number", nobody can take it away from you, and there is no phone service provider to pay for the privilege of keeping it.

The system provides high-quality, real-time full-duplex voice calls between endpoints, and uses only open source software components. This includes the voice codecs, which can real-time switch between OPUS (for high quality) and Codec2 (for ultra low bandwidth) without any frame loss.

But LXST was not only designed for telephony and voice calls. In fact, it is a general purpose secure signal transport framework, that allows sending any type of analogue or digital signal over Reticulum networks, either efficiently encoded or completely uncompressed. The protocol currently supports transporting up to 32 simultaneous signal carriers with up to 128-bit floating point precision in a single stream.

It also supports transmitting digital signalling and control data in-band with the carried signal frames. This allows creating almost any kind of real-time application.

At this early stage of development, the framework includes ready-to-use primitives for telephony, signal input, output and mixing, and network transport. Future development will focus on even more primitives such as:

- Real-time distributed radio communications
- Decentralized 2-way radio systems, similar to (but more flexible than) trunked systems such as DMR and P.25
- Media broadcasting for information content such as podcasts and digital broadcast radio that anyone can set up and use
- And many more useful and interesting applications

If you want to dive deeper into this, there is more information available on the LXST source repository and in discussion threads. It's still very early days for LXST, but if you're interested in this kind of thing, it might be a good time to jump in.

OK, having got Nerd Sniped by @sammachin earlier in the week, to try out @osmocom's Asterisk build that adds VoLTE/VoWiFi support osmocom.org/news/297

I have received my new USB Smart Card reader (one with a standard sized SIM slot as well)

amzn.to/4cfuRCu

And have managed to extract the required info from the SIM to find the endpoint for setting up the IPSEC tunnel.

Next step try and create a tunnel

TIL: an exhausted #cmos #battery can cause #Linux to behave strangely after a hard #shutdown (caused by a #UPS being incorrectly turned off) - it uses the BIOS time to check the filesystem block timestamps, and as it had gone back to 2012 the OS thinks the filesystem time is in the future! (At least the hard drive on this server isn't on the way out yet which is what I had feared, but this required an emergency visit to the office as it is the main #VOIP #PBX) #sysadmin

Linux terminal screen, a filesystem check has failed as the PC system time has switched to 2012 due to an exhausted CMOS battery (when it is 2025!)

Had a thought over the weekend that our #VoIP service has a separate E911 entry from the main account, and the address might not be sync'd.

Sure enough that's the case - if you have an E911 provider, you should prob check that. If I'd called 911 they would've been dispatched to the old place. Ugh. Fixed now.

VoIP Call Data Records (CDRs) are still one of the most reliable tools for keeping #VoIP systems running smoothly. ☎️ They provide a granular view of call quality, latency, jitter, and packet loss — all critical factors that directly impact voice performance. 🗣️ CDRs also offer historical insights that help to pinpoint recurring problems, track trends, and ensure networks are properly provisioned. 👍

This article digs into the 3CX VoIP PBX and the call data records that are sent to #Graylog. Read on to learn about configuring 3CX for CDR logging. 👇

My Actual Brain

I am looking for a VOIP service I can use for banks and different social media apps for my business. I am an American, but i do not live there.

One service has a premium plan, that offers AI summaries of stuff. So, I can pay less and avoid the AI?

Sounds too good to be true.

I wrote a simple guide for purchasing a VOIP DID phone number from the US and setting it up to send a push notification to an iOS app. Useful for people who switch numbers a lot and want one static US phone number to receive annoying text message verifications at. matduggan.com/how-to-get-a-did

Okay so, one of the local radio clubs got these Avaya things.
Outside of them doing VOIP and that one dude reportedly has two controllers for them, I don't really know anything about them.

Four G450's and three G430's.
Is there anything useful one could do with these, especially if they don't have any Avaya phones and don't plan on getting any?

Or should we just part these out?

Picture shows seven rack mount devices. Three 2u Avaya G430's are piled on a chair with a helixal 1800Mhz antenna under it and a SmartStore box with a threephase plug in it. Four 4U or 5U Avaya G450's stand on their side next to it.
