pjproject | Asterisk fork of PJSIP NO PULL REQUESTS OR ISSUES!!! | TCP library

I have built the FFmpeg with libx264 into static libs, here is my directory tree.

I am trying to make a simple SIP user agent using https://github.com/pjsip/pjproject. I can succesfully connect to a sip server (Twilio) and place calls to PSTN numbers using the pjsua_* interface. This works fine.

What I would like now is to get a notification (through a callback or such) from pjsip when the user that I am calling answers the call.

I am using on_call_state() to get updates on the invite, but this goes through the same states

CALLING -> CONNECTING -> CONFIRMED -> DISCONNCTD

even if the user rejects the call. So I guess I am not looking at the right callback for this.

How can I definitely tell if the user has answered or rejected the call?

Im trying to cross compile pjproject in yocto with ssl support but it errors out trying to build pjlib-test. Ive tried adding the openssl package to DEPENDS in my .bb file but nothing changes. Any help would be appreciated.

How do I create a HTML link to an emergency number like 911 or 112?

The RFC says

The phone number can be represented in either global or local notation. All phone numbers MUST use the global form unless they cannot be represented as such. [Emergency numbers ("911", "112")] cannot be represented in global form and need to be represented as a local number with a context.

From the local-context section I don't find it easy to understand what a "local-context" is, let alone what the correct one for this case is. It lists domain prefixes like houston.example.com or a numeric prefix like +1, and in one paragraph it says

A context consisting of the initial digits of a global number does not imply that adding these to the local number will generate a valid E.164 number. It might do so by coincidence, but this cannot be relied upon. (For example, "911" should be labeled with the context "+1", but "+1-911" is not a valid E.164 number.)

But the phrasing of this paragraph is again very confusing.

I am trying to compile pjsip library for iOS, but getting an error and I am following below steps

Step 1: Create a new file config_site.h in the project folder /pjlib/include/pj/ with the following code:

I want to create a Docker with asterisk 16, I can register my sip extension but I don't listen anything.

I can go to 8088 port too, modifying http.conf Also I edited rtp.conf with

I'm trying to make a call to a telephone number. I'd like to be able to make a call from the raspberry pi, and also make a call to my voip.ms phone number and be able to answer or auto-answer and play some generic .wav file.

This maybe should be titled "My current misunderstanding of things". I'm new to sip and pjsip, and I think I must be missing some part of the process I don't understand. I was under the impression that, if I register with voip.ms, when I make a call it would route to voip.ms and they would do a lookup on the number/address, and then respond with an address that I would then begin to communicate with.

I've compiled Pjsip on a Raspberry Pi 3B+ properly, for what I can tell. I can include pjsua2.hpp in my c++ applications. I've roughly followed this tutorial

I'm running into identical problems running a modified pjsua2_demo.cpp and the binary included in the pjsip build. For the sake of simplicity, I'll ask about the binary located (for me) at /pjproject-2.8/pjsip-apps/bin/pjsua-armv7l-unknown-linux-gnueabihf.

I have an account and phone number with Voip.ms and can become registered with voip.ms by executing the following script:

call_and_auto_answer.sh

This is not a duplicated question, other user had the same problem but this question add more info. I'm working on Ubuntu 18.

When I receive a call using VoIP with and asterisk server, my python script crash. This python script works in other computer but not in mine. So I tried to diagnose the pjsip dependency because the problem come from there.

I use pjsip as dependency of Python Most Voip Library

The pjsip installation process is the following:

I am getting following error while building pjsip as mentioned in this link.

When I run the make command:
