Thanks, but then I’m missing the next step, how do we configure the connection between Kamilio and the FreePBX servers ?

How do we configure the routes, public ip, internal FreePBX servers.

This make no sense to me at all:

Now everything is in place. You can start the VoIP service, creating new accounts and setting the phones. A new account can be added using 'kamctl' tool via 'kamctl add <username> <password> <email>'. (or try without the email) kamctl add test testpasswd test@mysipserver.com If you are asked for SIP_DOMAIN environment variable do one of the following option. 1. export SIP_DOMAIN=mysipserver.com

2. edit '/root/.kamctlrc' and add: SIP_DOMAIN=mysipserver.com

Kind regards,

I have been watching numerous videos on youtube in search of how to configure Kamilio !

I know we I need the Sip Server, but don’t know how to get it configured. The installation is obvious with the commands as a root user.

Brief description of the project:

Have quite a few customers we want to move from PSTN (AT&T primarily) to a Voip/Sip solution. So instead of setting up 1 FreePBX and 1 public ip, we would rather use 1 public IP to many FreePBX servers on the backend.

I haven’t been able to find one video on how to configure this SIP server, and was hoping somebody here might have some clues to lead me in the right direction.

I found one company that would help us, but they said at least 20 hours just to configure the first customer/freePBX installation. If we could get help setting up the first we should be able to figure out the ones to come later.

Any help would be appreciated… We know the product is awesome, we have the keys but don’t know how to run the thing or even get it started !!

Hi Joel,

Thx for your reply.. I see your point, and you are already throwing me off with the dispatcher group…

Let me try and explain what I would like to do (if possible):

I want one single public IP assigned to a domain name(for now), to be the contact point for all VoIP phones, with all our different customers, from there the SIP Proxy (Kamilio) would be the master and make sure the customers phones are connected with their FreePBX (one FreePBX for every customer) behind the SIP Proxy.

I want to hide the topology behind the SIP Server for security reasons.

I don’t know what the best approach is to the above goals, as we get more customers we would most likely get a SIP Proxy cluster for uptime and redundancy purposes. But first we need to show we can get it going before we can bring on any customers. The FreePBX as a standalone service I have figured out, and no problem connecting phones over the internet and such.

Is the best approach to expose the SIP Server directly to the internet (avoiding fw issues and nat confusion) or am I going down the wrong road here?

My 2cents:

- Agree, Kamailio training makes your life easier. Specially because even if you know SIP (if you don't that complicates everything), you need to understand how Kamailio works internally, what are dialogs, transactions, branches, etc, the different route blocks, blablabla, what goes where... To be honest, once you understand that, you can do literally whatever you want. If you don't know something, you can ask and someone will give you some help, and when you read it, you will actually understand what whoever is trying to say. Why I'm saying this? Because I could answer your questions to the point, and still you would get a system running but you would have no idea of why or how it works, so what happens when you run into an issue?

- To the point, you probably need different sets of domains and dispatcher groups, and then depending on where the call is going to, route to a specific dispatcher group? This is just an initial suggestion, as you haven't given many details, there are just so many ways of doing things that we would need a little more information on how EXACTLY do you need things to work...

Hi Joel

Your scenario was spot on the one I was thinking about.

If we can have Kamilio handle all the traffic that would be the best approach I think. But do I need a public IP for each PBX server to handle the RTP traffic?

We would definitely not expose the PBX server to the internet, for the same reason you write below.

I think one way to separate A, B and C from each other if I used different port numbers for every customer? Sip 5065 for A, 5066 for B and 5067 for C?

As far as I have read in the cook book it seems that Kamilio can share DB with the PBX server(s) and that way handle registrations for any given PBX server?

It gets a little more cloudy for me when we get to the handling of traffic and connection to the PBX server…

If I only had residential customers with 1 line it would be easier as they could all go to the same PBX or a cluster of them. But I need to have individual settings for my different business customers so they can have their own rules, ring groups and such.

Hi Kenneth,

What you are talking about is a pretty common installation. As a starting point, you will need a way to differentiate your clients so you can send them to the correct PBX.

For example:

You have customers A, B, C and PBX servers 1, 2, 3 respectively. (A1, 2B, 3C). Your domain name is sip.knudsen-nordic.comhttp://sip.knudsen-nordic.com.

Say A wants to register to their PBX, how would you make sure that Kamailio forwards that request to PBX1 instead of PBX2? Then C wants to register and Kamailio has to send the request to PBX3 this time, etc. There are countless ways to do this, and any can be correct or wrong. This is why the big picture matters a lot, Kamailio can handle and manage all registrations by himself, or it can relay them for each PBX to manage their own registrations, etc.... Would the PBXs have public IPs (with traffic restricted by a firewall or similar) or would they have private IPs and you have to deal with NAT, etc.? There are lots of variables here.

Regarding having the PBX exposed directly to internet, I would strongly suggest to avoid that, fraud attempts in the SIP world WILL HAPPEN literally minutes after you expose the PBX, and, it is quite common for config mistakes to cause huge fraud carrier bills.
