Ring Delay Device

[cabletech503]

I know this isn't part of the callblocker program, so if you want to delete this post feel free. But in the past 4 days I've received over 60 junk calls (Callblocker web gui is very red!). The program is working well with the combination of Nomorobo, wildcard number filter, and filter by name. I was wondering if anyone knew of an in-line device that I could put before the house phone to delay that first ring so that Callblocker could do its thing and we never hear it. I'd leave Callblocker's modem on the main line and just delay the house phone.

1. does you provider support SIP, callblocker can also act as an SIP client
2. a telephone system (PBX) may help. personally i am using a fritz-box (https://en.avm.de/products/fritzbox/fritzbox-7590-ax/technical-specifications/) as PBX, however i am connected to the provider via SIP and not by landline.

The advantage of SIP against landline/analog is that you earlier get the phone number of the caller, in most cases i do not hear it ringing at all.

Thanks for the reply. That sure would be nice, but no, I'm not using SIP, just a standard analog line. I've spotted a couple of devices out there but they're not available for purchase ("First Ring Suppressor"). I've looked at a couple of the commercial call blocking devices, and some of them may or may not have first ring suppression, but it may be only if they're in that unit's blocklist.

I've been running callblocker for just over a year on this laptop now, and it's been working great. Now I want to start running some reports. I think I saw info on how to extract the call log, but that's what I'm going to look into next.

you can access the call log via sudo journalctl _SYSTEMD_UNIT=callblockerd.service + filtering

Thanks! Just extracted some data filtering for Incoming. Looks like 984 calls over the past year, 397 of which were blocked. 190 calls since September 20, with 145 blocked. So much for Shaken/Stir reducing bad calls.

i am suffering the same its really a pain those spam calls. Nowadays i get quiet a lot computer fraud calls, marketing/insurance adv. calls dropped due to law changes.

Yesterday was 27 calls, 5 actually made it past Callblocker, with 3 of them legitimate.

I thought about building a circuit to do the first ring drop, but instead of taking hours to do that, I bought a Digitone Proseries II call blocker, just installed it. Connected it in series with the phones, in parallel with Callblocker system. It does block the first ring, and Callblocker still gets the CID info and is active. We'll see. The Callblocker software is so much more user-friendly than the Digitone box.

Just a datapoint... Today, 11 calls. 10 blocked by Callblocker (correctly) based on my blocklists / Nomorobo, but only 2 of those blocked by the Digitone (they were V0* names). The 1 legitimate call was allowed through. Phone only rang for the one legitimate call.

nice that blocking works, you really get a lot of spam calls!

[cabletech503]

Been nearly a year since I checked in... Callblocker still running perfectly. Has blocked 36 calls so far today - all spam calls - on my home phone. Thank you again for this software! For some reason, this week has been a flood of calls.
