Successfully migrated my rotary phones over from a FRITZ!Box 7490 to a Grandstream HT802 and an Asterisk server on my #NixOS server.

Finally I’m able to assign any internal numbers I want and don’t have to go with the Fritzbox’s stupid defaults.

My dial plan now also automatically distinguishes between internal and external numbers. Everything with 3 digits or more is treated as external and routed through Telekom.

What a relief!

Dear Fedi,

I would like to have a simple SIP Client, connected to EPVPN, that plays a simple Audio-File.
Other than https://docs.asterisk.org/Getting-Started/Hello-World, I didn't find any good Resources. The Asterisk Documentation just talks about it being an SIP Server.

Do any of you know, how to do it?
Any Help would be appreciated

Back in 2007/2008, when I was doing my civilian service driving for the Göttinger Tafel, I sometimes had a coworker who would tell me about his #Asterisk setup nonstop, down to the tiniest details.

Now, 19 years later, I’m finally setting up my own Asterisk installation. So far, I have it running in a #NixOS container, and I can call it from a SIP client on my iPhone to get a spoken “Hello World” reply.

I'm building-out an IVR in #Asterisk for remote access to my PBX. It's just for me, and just for giggles. Decided to use the open source Kokoro TTS to create some custom prompts that weren't my own voice.

Pretty sure that if a real human telephone operator back in the day sounded like this, they wouldn't be employed for long. Sounds like a clip from an audiobook for a tawdry romance novel. 🤷‍♂️ (I'm using it anyway.)

When setting #FreePBX with special #SIP Alert-Info on inbound route on DDI number, for distinctive ringing on #extensions linked to a ring group, beware that Alert-Info does *not* get transferred to extensions across intercompany #trunks (those with # at end of number)

Workaround to achieve this without custom #Asterisk dialplan (assuming you have outbound route with escape digits with direct route to inter-PBX #trunk)

* Set up ring group on remote #PBX with desired Alert-Info and extensions to be rung

* On ring group on original PBX, add local extensions list and at end route to remote ring group (for instance if ring group 610 and your escape code is 77 for remote PBX put 77610# in ring group extension list)

now distinctive ringing works across both PBX!

From Analog Phone to FreeBSD Server Interface

In his latest write-up, Alexander Deplov restores a vintage Panasonic desk phone and connects it to a FreeBSD server via a Grandstream HT801 and Asterisk, turning the handset into a physical command menu.

If you’re interested in creative integrations or bridging old devices with modern systems, this is worth a read.
