Asterisk hangup detection

After hangup ""most""" telecos send reverse polarity signal to callee to signal hangup. But some
telcos does not do it.

There are 2 ways to detect hangup in asterisk in India. do

1) Add answeruponpolarityreversal=yes in /etc/asterisk/zapata.conf . If it does not
solve the problem then do

2) add buysydetect=yes, busycount=4, busypattern=750,750 in /etc/asterisk/zapata.conf.
Else
3) edit zonedat.c file in zaptel/zonedata.c. //This would also take care of other tones

But you should be done by 2. For 3 you have to recompile asterisk source.

This should work for hangup detection in india. This would do for busy detection and
hangup detection.

    Hi,
    I just got hangup detection working with busypattern=0,750 over BSNL lines. But I still have problems with answer detection. With just busydetect=yes , dahdi line is answered just when ring starts. If I enable call progress line is not answered until I end the call from the trunk side which is not I want.
    Can you post your configuration settings and what telco are you using?

Your Inconsistency is a Feature, Not a Bug

We are living in the Golden Age of Guilt. You know the feeling. You wake up, check your phone, and are immediately bombarded by the "High-Performance" brigade. The 5 AM Club. The Atomic Habit builders. The Tech Bros meditating in ice baths. They all have the same message: Consistency is King. If you aren't grinding 24/7, if you abandoned that hobby you started last month, or if you can’t focus on a spreadsheet for four hours straight, you are told you are broken. You lack "grit." You need to buy another book to fix your "laziness." But what if I told you that the self-help industry is gaslighting you? What if your inconsistency, your fickleness, and your refusal to stick to the plan aren't moral failings—but the very biological features that keep our species alive? 1. The "Death Spiral" of Perfect Discipline We tend to think of discipline as the ultimate virtue. But in nature, perfect discipline is often a suicide pact. Take the Army Ant....

LLMs have already taken over the world. Dont be left behind.

You’ve probably already read about how Large Language Models (LLMs) like ChatGPT, Gemini, and others are growing in popularity. Many say they are “taking over the world,” but the truth is even more striking—their impact is already massive, though in ways we often cannot easily quantify. Understanding Tokens At the core of this impact is the concept of the token . A token is a unit of text measurement used by companies to calculate usage and costs. Roughly speaking, one token equals about three-fourths of a word. For example: A page of text contains about 225 words , which is nearly 300 tokens . Across the world, there are an estimated 130–190 million books , which equals a total size of 15–20 trillion tokens of text content. Now compare that to social media: every day, around 500 million tweets are posted. In one year, that’s roughly 200 billion tweets , amounting to about 5 trillion tokens . Beyond Books and Tweets: Other Human Text Reservoirs Books and tweets are only two exampl...

Common theme across important essays

 So I asked chatgpt to identify common theme across important essays in life, economics and social science. This is what it said  Below is a formal, analytical synthesis of all the essays you requested summaries for. By examining arguments across sociology, psychology, leadership, economics, AI, creativity, and science , we can identify the single most repeated theme and the supporting sub-themes that appear again and again. The Most Repeated Theme Across All Essays Excellence, progress, and human achievement emerge from small, structured, consistent actions rather than from dramatic talent, inspiration, or centralized control. This theme appears everywhere — whether the subject is elite performance (Chambliss, Ericsson, Csikszentmihalyi), leadership (Greenleaf), learning (Dweck), creativity (Graham), complex systems (Hayek, Read), sociology (Putnam, Granovetter), or even scientific progress (Asimov, Feynman). Across fields, the message is consistent: Big outcomes ar...
