How to generate sip address on browser using asterisk

Question

I need to generate a dynamic sip address on browsers so that my asterisk server can place a call on the same sip address. This way my web browser will become a sip client which can receive call.

I can see that webrtc is the way but I don't know how can I generate sip address on my browser?

Thanks

You can check my post on Asterisk 12 + Realtime + WebRTC : Websocket connection fails with asterisk 11

On top of that, add a WebService to insert a peer into the table sippeers. This Webservice would be called by your system to create the peer instantly available for a registration using SIP or whatever (SIP over WS/WSS, WebRTC...)

If you're working on Unix and need a .Net WebService, you can use NUSOAP and something like this : (sudo nano /var/html/www/mywebservice.php`. This is a basic implementation I used for testing.

<?php
require_once("nusoap.php");


$namespace = "http://yourdomain.com";
// create a new soap server
$server = new soap_server();
// configure your WSDL
$server->configureWSDL("AsteriskRealtime");
// set your namespace
$server->wsdl->schemaTargetNamespace = $namespace;
// register your WebMethod
$server->register(
                // method name:
                'HelloWorld',
            // parameter list:
                array('name'=>'xsd:string'),
                // return value(s):
                array('return'=>'xsd:string'),
                // namespace:
                $namespace,
                // soapaction: (use default)
                false,
                // style: rpc or document
                'rpc',
                // use: encoded or literal
                'encoded',
                // description: documentation for the method
                'A simple hello world');



$server->wsdl->addComplexType(
   'AsteriskExtensions',
   'complexType',
   'struct',
   'all','',
   array(
      'name' => array('name' => 'name', 'type' => 'xsd:string'),

$server->wsdl->addComplexType(

   'array','',
   'SOAP-ENC:Array',array(),
   array(
      array('ref'=>'SOAP-ENC:arrayType','wsdl:arrayType'=>'tns:AsteriskExtensions[]')

You need to create sip user in asterisk like in any other case and register to it via WebRTC, but first you have to enable it in configuration. Hear you have tutorial that I use to start.

In case you want to create dynamic sip users you have to use realtime in asterisk, then your configuration will be read from database. Useful links how to start with realtime: https://wiki.asterisk.org/wiki/display/AST/Realtime+Database+Configuration https://wiki.asterisk.org/wiki/display/AST/SIP+Realtime,+MySQL+table+structure
