Excellent, thanks Daniel!

Hello,

you can set the local socket to be used for sending current sip message by:

$fs = "proto:ip:port";

provided that you have listen = proto:ip:port

There is also a function force_send_socket(...), but takes only static string parameter.

Cheers,
Daniel

Hi Daniel,

Listening is ok, incoming calls are my smallest concern.

But how do I tell kamailio to initiate the call from a specific IP (depending ont he user/pass combo is something i can imagine how to do )

Thanks

Hello,

if you don't have too many IP addresses that you have to use, then you can add many listen parameters in kamailio.cfg.

Otherwise, I think you should considering a firewall that will do translation of a source IP based on receiving on a specific port from kamailio. It should be more lightweight and you can control it independent of kamailio.

Hi Folks,

I am looking for a solution to do the following, basically an SBC-like solution.

I have an internal asterisk system that should make outbound calls towards a provider, but that provider authenticates the customer based on IP address. And I have many such customers. The provider is not willing to make changes to his practice…

Asterisk is bound to a single IP, so there is not much I can do.

I was thinking about creating several outbound accounts for asterisk, and then a multi-homed Kamailio would do the following:

If request comes from user1, Kamailio would send the request to the provider from IP1.

If request comes from user2, Kamailio would send the request to the provider from IP2.

And so on, for as many IPs as many customers I want to handle.

Is there a more elegant way to do this?

If not, how should I implement this?

Thanks in advance,

Attila
