Hi List, I am looking for some advice. I need to come up with a conference solution that will allow users to join mainly to listen to a guy talk about a product for an hour. My main concern is the client side. I need people from within firewalls to be able to join the conference with speakers built-in their laptops or computers. All I know is that Skype works in most of the customers this guy will be addressing. I am considering the following options: 1-Skype-like softphone for *. is there any? 2-Just do audio streaming and have the customers use windows media player. (I dont know how to do this) 3-Use some kind of Softphone with VPN... 4- Do Softphone--->Port 80---> SER--->Asterisk w/meetme. Whatever solution I come up with MUST allow anybody to listen in assuming nobody can change firewalls. Any one has already done this? Any feedback will be much appreciated. Thanks, Sergio
Since all would be listening, it's good to have a web streaming. Users could just use the media players rather than going for new softphones. This mailing list is not the appropriate one to discuss the above. But if you want to consider the asterisk solution, we can very well have the audience to participate in conference say for Q&A session. You could could use IAX2 clients behind the firewalls. ~Vamsi On 4/19/05, Sergio Veltri <sergio.veltri@gmail.com> wrote:> Hi List, > > I am looking for some advice.

We have found a new thing called 'the pub' It even provides beverages. Trust me, you can't find a program that can do that!

Thanks Vamsi for your feedback.
I would love to do it with Asterisk since I can do a lot more eventually.
I did try a couple of iax2 clients and I couldnt go past the FW in a
particular customer.
Thanks for your email.
Regards,
Sergio,

Stefan,
Thanks for your feedback. I am testing everything to find the right
solution. It is an interesting project since the listeners will vary
everytime. Most of them are corporate users and thus unable to touch
the corporate FW.
I found a large international corporation that allows me to run tests
from within their networks but without touching the FW. So that is
good. So far none of the iax2 clients worked. The only thing that
works is Skype and the MSN only for internal voice. They cant use MSN
to speak with other MSN users outside their network. So I assume they
either opened the Skype ports or Skype just happened to work.
I will start playing with streaming audio and see what happens. My
only concern here is that streaming usually does a little buffering
before playing the audio. This might be an issue since they already
have a chat system for questions an answers. So if someone asks a
question via chat the speaker might get it when he is on another
topic.
But I would love to make Asterisk work. I am not giving up on it and
that's why Im on this list.
Take care and I will let you know how it turns out and / or if I need
help with a solution.
Thanks againg

None that I know of. But IAX isn't bad in most of the firewalled
environments, give it a try. It only has to get a udp socket open for
an outbound connection (may well be NAT-ed) and to receive the answer
packets back.

This would mean exactly the same prerequisites as an iax-based
solution as the media stream (usually udp) has to be received by the
media players. One technique that circumvents this is using HTTP/1.1
streaming which may or may not work through an application level
http-proxy.
> 3-Use some kind of Softphone with VPN...
Again, if you are able to do an outside connect through the firewall
(as with openvpn which uses udp or with ipsec which uses ip), you can
also do some other things by this means (e.g. iax).
> 4- Do Softphone--->Port 80---> SER--->Asterisk w/meetme.
Only reason for this might be an application level http-proxy that
allows for outbound 'connect' calls, since I don't think you want to
encapsule SIP in HTTP, do you?.
And for the outbound 'connect' method, port 443 might be a better
choice for your port number, but you have to choose a protocol that
uses TCP and only one single socket for this to work.
Maybe using iax over some sort of UDP-in-TCP tunnel could work (like zeebeedee).
