What am I fishing for here? #telephone calls 😁

This is all above board (as its internal monitoring)- but old tech way is surprisingly most GDPR compliant - it separates call metadata (which I don't want, I can get that from other sources) from audio which I do want.

I'm not even interested in exact *content* of calls here, what I'm monitoring is overall audio quality to make sure nothing is glitched / daleked at our end now calls are 100% #VOIP (alas, I can't do anything about ropey #LTE networks our staff and service users might be using)

I'm also testing how #Grandstream #ATA and cloud #PBX handle long telephone calls (such as intercept feed from the other #PBX)

Contents of #tape are not kept long term, they are be erased once I've assessed the audio quality..

#AbsoluteUnit of #DECT #telephone set from #Motorola - updated version of BT Elements with rugged case, long antenna and separate (analogue) base unit (not shown in photos as its currently hanging off map pins on my office notice board with confidential stuff on it)

Got 200+ metres range even with base unit quite low down (my office is in a dip) and position not exactly optimised for RF, could make calls from adjacent housing estate - from a distance it does look rather like an #Airwave terminal, resisting temptation to stand at top of road and watch leadfoots slow down 😁

Connected to #Grandstream ATA, also works well in next door office, so I can now move between both and keep same extension number

About £70 with base station, might also be good for #CCC and #EMF type events?

Flaw in #Grandstream #VoIP phones allows stealthy eavesdropping

#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 😁

Been deep in the homelab lately, ergo the quiet :)

Almost done building a full multi-VLAN network: Guest, IoT, Media — all isolated and humming.

Snagged a used Zyxel GS1900-24HP switch + a Grandstream GWN7660E AP — both running like a dream (aside from a small surprise from a switch when it comes to noise). As well, couldn't recommend the AP more!

Some cable management left to be sorted out, but soon 😆
