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!

I'm looking for help with debugging a yate VOIP/SIP/RTP issue. I have a number setup to redirect to a sound file after a timeout (stand in for an voicemail IVR). When called from an internal number registered with yate it works. When called from the outside number (yate acting as a SIP client) it doesn't. Yate says it routed the call to the announcement but I don't see that reflected in the SIP/RTP traffic, the call keeps ringing until I hang up.

Hardware I returned to Xfinity this afternoon. The Arris telephony modem was about 20 years old. The cable box / DVT was not much younger.

We dropped cable TV, VOIP, and stopped renting modems (bought my own Arris S33v3) very recently, saving hundreds of dollars per month on the bill.

Now the other two are ported - all the #analogue #trunks are ceased and all traffic to and from the #PSTN from this #PBX is now #VOIP (using #PJSIP trunks on #FreePBX )

I disconnected all the analogue lines as #Openreach leave battery on them, that way they show as RED alarm on #Asterisk and won't be selected for any calls (worst case is they return a busy trunk status and the route will go to the next trunk, but I've taken away all the analogue circuits from every PSTN route)

#Telecoms #Telephony

One (1) #telephone number successfully ported to #VOIP, one more left to go (there's 2 pairs for main and aux line, provisioned on same number but those will go to 3 channel #SIP trunk)

For some reason #Openreach have left battery on the pair (I would have thought they would want to recover capacity on the line card and it would just go dis, as there are still going to be a handful of customers remaining on #PSTN circuits.

I thought a lot of "analogue" trunks these days were literally just a SIP ATA connected to the copper pair at the Telephone Exchange (or from a street cabinet) but it looks like Openreach really are getting the last out of the old #SystemX kit!

There is no dialtone or even NU tone, just some noise..

#Telecoms #Telephony

Just over a month and I've tamed all the #trunks (with abundant snake heads at the end), made sure 1500+ #blighters are yeeted (with more trying every day) got inter #PBX #trunk working between on-premises and cloud #FreePBX - just waiting for porting of first analogue number to check this (and CLID presentation) works and then main office one can follow.

Took many late evenings, a lot of research of everything from old #BritishTelecom training manuals to some from Universities in India and the Indian telecom companies, and I've learned a lot more about #SIP even since 2008 when I built the first #VOIP #PBX used at work.

Thankfully #routers seem to handle #SIP over #NAT a lot better than they used to (even got an extension it working over #LTE with #Linphone)

#Telephony #Asterisk

As an experiment, I asked #MS365 #Copilot to explain how to set up #SIP trunk on #FreePBX using #PJSIP (consider that I have already successfully set up several of these, to external providers and an inter-PBX line between two servers).

Results it returned were horribly mangled and mixed up from various providers sites, if you followed them the trunk likely won't work at all, and even if it did it would end up in completely wrong context/dialplan.

It didn't mention such things as fromuser and took a few prompts to point out potential firewall issues.

You need to know (or learn) the basics of #telephony before starting, or else it will all go tits up very quickly - #AI is still no substitute for "boots on the ground" who have put in research for what they are trying to achieve..

Building new #FreePBX #Asterisk #VOIP server (about 10 years since I built the last one) was also an eye-opener of how much #tech world seems to have been deskilled with the rush to #cloud (even before AI) - it seems fewer folk want to build a server from bare metal or even VPS and are flocking to proprietary cloud #PBX (that nearly all run Asterisk under the hood anyway), it might be that #telephony is "uncool" but also remaining engineers have simply stopped helping one another, perhaps not wanting to aid the competition?

I didn't even get much AI slop when searching for info on community forums, as there is so little there and many unanswered threads..

#Telephone set #BritishTelecom 8746 now with replaced 21A microphone insert, working correctly with #Grandstream #HT802 v2 ATA linked to #FreePBX I built on cloud VPS - accepts both #MF (tone) and #LoopDisconnect #dialling (although dialling a full UK mobile number is quite a long process and I had to make sure the timer was at least 4 seconds (or the digits get sent to register before you've dialled any 0 and call fails due to wrong number being sent to #PBX !)

Ring voltage (set to 55V RMS) is strong enough to ring the 4k bell in 8746

So currently this corner of the office looks like its back in 1980s 😁

After seeing the #39C3 talk on #smartwatch​es' #security, I wonder if there are any simple wristband #phone​s for #children or the #elderly available: just #telephony and #SMS (via user-inserted #SIM card) to a few predefined contacts and #GPS for #emergency services.

I've had a PBX box for a while now, and I've been bugging @lpbkdotnet here on a few tips and tricks.

I have the (I don't know wha the name of it is), "master telephone" responsible for being able to programme the PBX -- this is the only way this can be done -- including working out extensions for telephones.

In the course of my (albeit very naive/young) #telephony interest, I've come to own a few GPO devices which have a no. 7 handset in them:

https://www.britishtelephones.com/hands7.htm

These aren't common at all.

But.

Ideally, I'd love to be in a position where there were a way to mute any GPO phone, but to have a modified external "light" or some indication that if such a phone were on "mute", that it we're obvious.

When I say "mute", GPO telephones have a mechanism to do so in the middle, if such a switch is fitted.

So, @lpbkdotnet -- I guess what I'm asking in your experience is whether:

1. I can get "mute switches" and fit them to any GPO phone?

2. Given the proviso that Handset No. 7 is rare, how might I connect some sort of "external light" indicator to make up for that?

I am aware of the vintage-radio.net forum, but thought I'd find the wisdom the crows here first.

Thanks everyone! :)

Urgh, thanks to the Wayback Machine i now fount the old documentation customization. But of course neither the customization tarball nor the documentation on PUI redesign where archived.

Does anyone have a copy of the files

and more important

?

Other versions of the branding tarball for the 870 would work too.

so I have a rotary phone that I bought off of eBay. However, it has a very strange connector. At first I thought it was some strange coax variation. It's threaded, bigger on the bottom if you're holding it so the end is up. I sent ChatGPT a picture of it and it said it was a 505A bell connector, used up till the late 70s. Do y'all know where I can find a suitable adapter for such a thing that converts it into RJ11? For the life of me, I cannot seem to find one. I searched round 4-prong to RJ11 as well as 505A to RJ11 adapter, as it also listed that as one of it's names as well.

On #reticulummeshchat #reticulum #reticulummesh #meshchat you can over #radio
1. run multiple #lora #rnodes on one computer.
2. make voice calls over #433mhz ( #ism band at low 12dBm power) between two #rnodes , but of course with delay.
I used #heltec #t114 (version 2 ) and two #lilygo #tbeam for
#VoiceCall #telephony
(un/like #meshtastic )
3. image files can also be transferred

Is it worth paying #Anveo $15 per year so #E911 calls continue to work through the #VoIP box providing service to the four cordless phones in our house?
Pro: If we do call 911 through one of those phones, it's probably an emergency, and every second could matter.
Con: This happens once in a blue moon, we can just use our cell phones.
(I ask myself this question every year before paying the $15. I'm curious to see what other people think.)

Sorry for the late response.

The #InviziblePro app sounds like a compelling solution that one can use mobile devices, with the help of friends at #FDroid.

Unfortunately, it seems #Australia don't allow ethical #telephony devices into the country. What we mean when we say that is devices that can easily be flashed with ethical #FOSS firmware. Otherwise it would be a contender.

Today we prescribe to #APAB or #AllPhonesAreBad.
