EADDRNOTAVAIL when trying to connecto to Twilio

[psukys]

Hey, appreciate that @cwysong85 built the foundations on UDP communication for SIP.js!

Unfortunately, I do not know how to correctly (?) attempt to connect to Twilio's SIP service with this library. What I've tried was using the example examples/uas.js

To set-up Twilio's SIP endpoint, I've used this guide. I've verified through Zoiper (Android client) that it's possible to use the functionality.

The error that I get is:

I've as well checked Twilio console, it does not report on any attempts to connect to it.

Since you are trying to register to Twilio, try these settings for the SIP UA:

const server = new SIPUDP.UA({
    // provide a valid URI here
    // The host and port are used to start the server
    uri: 'uas@' + host + ':' + port,

    // auto start...
    autostart: true,

    // register to Twilio 
    register: true,

    // trace sip or not
    traceSip: true,
    hackViaTcp: true,

    // diaabke UAS support
    doUAS: false,

    // Custom media handler - Enabled for custom media handling
    // dev notes: I've only implemented this library using a custom media handler.
    // I'm unsure how the built in media handler works with the UDP transport.
    // mediaHandlerFactory: new UasMediaHandler()
})

I changed register to “true” and doUAS to “false”.

[cwysong85]

@psukys Looks like there needs to be more work done when using the "register" function. This library was hacked to support more of a UAS than a UA with UDP transport. I'll be looking into the code and modifying it to support registering as a UA and using UDP as the transport.

Closing this issue since I haven't received any other feedback for this issue.

Is there any way to be a sip proxy and support websocket register to udp register?

[cwysong85]

@forjuan This project is geared towards being a client/server model more than a proxy. If I were you, I'd look at Kamailio and install the WebSocket module. That should give you everything you need in a proxy with WebSocket registration and UDP/TCP support right out of the gate.
