WebRTC in the cloud

[prathibhacdac]

I've installed browser phone application in amazon cloud. I'm not getting the video.

In firefox, I'm getting STUN failed,add TURN server. Asterisk server in turn acts as the TURN server. Where should I add the TURN server in Browser phone application and whats the format for it?

The same thing was happening to me, I was not getting the audio. So I tried it on my local server and it worked.

In local server it is working for me too. Now I want it in cloud.

You must watch this video:

There are specific settings in rtp for it to work.

I tried this, it is working locally. but not working on AWS.

There is no mention abt rtp in the documentation.

[prathibhacdac]

Can you point me where it is mentioned?

[InnovateAsterisk]

It could be just that the AWS firewall is not allowing the RTP packets inbound. Allow all the UDP packets inbound in your security group.

[InnovateAsterisk]

Also, you can debug the RTP on the Asterisk box, and see the packet flow. Post a sample.

I've allowed all the traffic. Its working now. Does hosting in cloud resolve the latency?

Once I got the video. But now I'm not getting it.

I've allowed all the traffic.

Make sure its just UDP you allow all with... otherwise you will have trouble.

Does hosting in cloud resolve the latency?

The thing to remember here is that Asterisk is a B2BUA, meaning that the media always flows through it - especially with DTLS (the encrypted RTP). This "3rd point" in a conversation between two people can add latency. People say that from about 300ms latency can effect call quality. To reduce the time it takes for packets to flow from one person to the other, the most direct path is best - this means Peer-To-Peer, but Asterisk doesn't support this. (It probably never will)

You don't have opus codec installed (13:01 in the video)

I've creating an peer to peer video call application. Is it possible to integrate asterisk with it for call routing? When a user dials a number(eg:100), the call should get routed to any one of the free call taker?

[prathibhacdac]

Will Siperb be suitable for this?

Will Siperb be suitable for this?

Siperb is designed to create private networks for Peer-to-Peer audio and video calls (with text and media), it does not use Asterisk as a switching service, it uses OpenSIPS. This should make it feel a lot like WhatsApp.

One of the "peers" however, can be your Asterisk or legacy server like Asterisk (on-site or hosted), meaning that this could be your office or home PBX, providing you with all the functionality of Asterisk that you are used to, like queue participation etc. In this connection mode, the calls are transcoded and formatted to be regular SIP. This should make it feel a lot like a regular PBX Extension.

At the moment Asterisk is only used for Voicemail, and for some Conference functionality. A user can send a public URL to invite participants to a conference, and this would route callers to an Asterisk Conference. This should make it feel a lot like Zoom.

[deepaksharma9899]

Can we change the server from asterisk to opensips. Will it resolve the problem of video?
