I often connect to remote systems via vncviewer (remote is Linux) or rdesktop (remote is Windows). It works great to share the remote desktop with a remote user. One thing I miss is to be able to talk to the remote user at the same time. Obviously, the telephone works. But where is the challenge in doing that? Does anyone have a suggestion for an app supported on openSUSE that allows this? Something that is not too complicated. We don't need conference calls or anything fancy. Just two computers, each with a mic and speakers. If we stay with Linux on both sides, we can add KDE into the mix as that is the desktop on both ends. I see many apps. But they always seem so involved. And some like a server to mediate connections. I would like to avoid that if possible. Just two client apps that talk to each other. Looking forward to suggestions. Preferably ones where the apps are actually used. -- Roger Oberholtzer -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

never used it, but would chrome remote desktop work? On 13 December 2016 at 09:56, Roger Oberholtzer wrote:

I would think VoIP, voice over IP. Yes, often they require an external server, when using SIP, to find one another. The server doesn't need to handle the conversation, just helps finding one another and traverse the router/NAT when people are on dynamic internet addresses. But if you happen to know the IP address of the other side you can directly initiate the conversation, I think it was with Ekiga. I don't have hardware now to try and tell you the application and the function that does it. But with NAT in the mix, things get more complicated. - -- Cheers / Saludos, Carlos E. R.

The IP addresses are known. I wanted to avoid SIP as each system would require a registration. If it comes to that then I guess it could be done. But not needing that would be best.

The problem will then be the router and NAT. I have tried direct VoIP only inside a LAN. maybe you will have to open some ports in advance. - -- Cheers / Saludos, Carlos E. R.

With Ekiga, apparently you can do client-to-client calls too, without a SIP account. When you're set up, try calling "894@jessen.ch" - you should get the hold music. -- Per Jessen, Zürich (1.4°C) http://www.cloudsuisse.com/ - your owncloud, hosted in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That was my thought too - you could run asterisk internally, but it's a bit of big gun for this.

That ought to be sufficient - I wonder if it works.

In a LAN, yes, I tried it. But I don't remember what app I used, I think it was Ekiga.

Well, you have to open the firewall, and the side receiving the call has to be listening on the outside, meaning that the router must be configured to forward some ports in advance. This may problematic if you are doing remote maintenance for someone that may not know how to do that, ie, that you do it for him. With an intermediary server in the mix it is automatic, but we are talking without one, direct. - -- Cheers / Saludos, Carlos E. R.

Everything is a target, but it's not a big deal - you get a lot of people trying to gain access to a SIP account, but it is so easily blocked. I've been running asterisk as our telephone system for at least 8 years. For Roger's purpose though, it's far too much effort to set up, I would say. -- Per Jessen, Zürich (1.1°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I might play again with asterisk, I would like to install it again. But I only played on a LAN. Facing outside I think it is bombarded by script kiddies. - -- Cheers / Saludos, Carlos E. R.

This is for communication with a computer and person in our measurement systems. They are usually on the road, and thus not on line. We will be using this when they are in for service in our garage that is 600 km from my office (hence all this nifty remote access). All machines are behind the corporate firewall. Which is another reason I would like not to involve a server. Unless my own openSUSE machine could server SIP information somehow. We do have plans for getting these systems on line when on the road. But that will be limited to when we need access. And at that time we would need to be more careful of unauthorized access.

It could with asterisk, but when I tested ekiga yesterday, it was perfectly capable of calling my sip office phone directly.

Many years ago, when we had an office in Alaska and another in Australia we ran a teamspeak server on our gateway Linux box. It worked well for both individual two person calls as well as conference calls. Teamspeak never did have the best security (it was designed for gamers) and anyone who could find such a server could coordinate calls on it. There were all sorts of love-birds using it late at night from what my server guy told me. -- After all is said and done, more is said than done. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So you are, in effect, inside the same LAN space. No NAT, but perhaps some routers and firewalls. Then it is far easier, just try with Ekiga. - -- Cheers / Saludos, Carlos E. R.

First thought - VoIP. Ekiga seems to be popular, so I tried it. I was able to establish calls both with a sip account on asterisk and directly to another SIP client.

Most modern IOT toasters have microprocessors in them these days. So if you could install linux on one of those while your wife wasn't looking, you could spirit to toaster into the computer room, and plug the earbuds from your phone into it. Set the Light-Dark control to medium, and push down toast lever to talk. Seriously guys...
