SIP phone on STM32F7-Discovery

Hello.
 
 
Some time ago we were wrote 3r33333. about how we managed to launch a SIP phone on STM32F4-Discovery with 1 MB ROM and 192 KB RAM) based on 3r33232. Embox . It must be said here that that version was minimal and connected two phones directly without a server and with voice transmission only in one direction. Therefore, we decided to launch a more complete phone with a call through the server, voice transfer in both directions, but at the same time meet the smallest possible memory size.

From Germany with love: the pioneer of IP-telephony comes to Russia

From Germany with love: the pioneer of IP-telephony comes to Russia

 
Interesting news: the company Snom Technologies GmbH, which in 2001 released the very first IP-phone in the world, intends to seriously settle in the Russian market.

Add encryption and push to normal SIP

Add encryption and push to normal SIP  
 
Hello Habr!
 
 
In this article, we would like to highlight several SIP issues when used on a mobile device, which are generally not known or not guessed by users.
 
 
One of the main problems is if you use any SIP provider (or your own IP PBX) on a smartphone, then with 99% confidence you can say that your data is unencrypted.
 
 
Probably many people did a simple thing - they sniffed the traffic from SIP devices to find the cause of any inoperability of the VOIP connection.
 
 
In practice, this means that all of your SIP conversations can also be easily captured, restored and audited on the mobile ...

"Right" call to softphones from AMOCRM (call2click)

Greetings, community!
 
Who was involved in the integration of asterisk and amocrm, he knows that it is possible to initiate a call from AMO only by originating. The original is when the server first calls to your extension number, and when you pick up the phone, a second call is made to the desired customer number. Sometimes this decision for various reasons does not suit clients or me.
 
 
Attempts to persuade tech support AMO to stick the possibility of placing links like "sip:" or "tel:" instead of calling the script amocrm.php with the original failed. Then this "crutch" was born. Perhaps ...

FusionPBX, or again-great, FreeSWITCH

In the same river


 
Relatively recently, I wrote myself cheat sheet on setting up FreeSWITCH. The configuration process described there led to a workable configuration in the test environment. The test was necessary to compile a preliminary idea of ​​what will have to deal with after moving the organization and launching telephony in production. However, when the move took place and the connection started in the working mode, the first activation showed the inoperability of the configuration: internal calls stopped walking.
