[Freeswitch-users] Freeswitch as A-SBC

Hi Guys!

 

I think I’m misunderstanding something. I beg you forgiveness with my
repeated questions but I am eager to learn and to try it, but I need to
understand it for that!

 

I understand that in the kamailio example, registration and authentication
(and location) is handled by the kamailio server, not by the Class5 server.
Is it correct? That means kamailio needs all the users credentials and
provisioning flows.

 

If that is NOT  the case, how does it handle the location if it just
transfer the registration to the “inside” of the network? I know only a bit
of kamailio so maybe it is just easy config.

 

I assume in that case Freeswitch would do the top hiding, Freeswitch would
send the registration to the network with its ip as from& contact. Is it
correct? And for incoming invites it would proxy the invite to the kamilio
which needs information about the location of the phone.

 

If that is the case I thik freeswitch would do the top hiding and media
anchoring. And kamailio would do the location information which I am not
sure how to do that without needing the user credentials. And how can it be
done here and also on the network node (where the existing logic search for
the presence)

 

Thanks again for your help

 

Helena

I recommend using a proxy server such as opensips. Freeswitch could be used
this way but a proxy server is exactly the sort of thing you need and would
have much for flexibility and more features such as load balancing or
dynamic routing.

Hello Helena 

Actually my scenario is exactly ... 

My Clients <--> Internet <--> SBC (FreeSwitch + OpenSIPs) <--> my internal
network <--> Class 5 (OpenSIPs) 

And followed this doc, is working perfectly.

Hi Delphini, all,

 

Thanks for the tip, I read the doc and it give me some tips but it is not
what I need. My design would be

 

Phones---internet--> FREESWITCH ----- internal netw with public ips --->
network node 

 

I need Freeswitch to pass registrations on to network node. That is very
important since provisioning in a hell on that network and trying to
reproduce it on freeswitch is out of the scope


 

But I need Freeswitch to handle the location information, since The network
would call the phones and this call need to pass through freeswitch and
progress to the phones after changing the ips according to the top hiding.

 

In my case the phones are connecting through internet, they are on the
“outside world”

 

Does it look like something do-able with Freeswitch?

 

Thanks again!!

 

Helena

Hi All,

I am newbie at freeswitch but what I have read so far seems a great project!

I am interested on deploying a freeswitch used as Access SBC for a network.
I am still trying to outline the design but I'd like your advice about the
feasibility of doing all that with freeswitch in a more or less standard way
(since I still have to learn a lot about freeswitch) conditions would be
something like:

-TCP via public link with apps
-UDP via private link with current network

-pass registers and invites form apps to network to handle doing the top
hiding. ( that point is critical since all the provisioning process is too
complex to connect the "sbc" with that)
-receive invites from network to terminate on app
-receive invites from apps to deliver to the network

-anchoring media to solve audio problems due NAT. But no codec transcoding

My initial idea was to set the network in the internal profile and the
external accepting incoming messages from all apps.

I'll appreciate your comments on if that is easy for a newbie with
freeswitch. I'll keep reading the files and the info!!

Thanks in advanced

Helena
