[SR-Users] Kamilio new user - help get going

[Kenneth Knudsen]

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?


Kind regards,

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...

I also took this training, it's worth it.

Look at you question business wise: how many hours are you willing to
spend on getting this setup (on a trail by error kind of way) and the
costs of those hours. Is hiring a consultant for 20 hours to get a ready
made solution really more expensive?  Maybe you could get the consultant
to spend a day with you to get the grips on kamailio instead of having
them build the solution?

You may get all your questions answered here if people feel inclined to
answer them in their spare time. You might get better answer if you ask
smaller more to the point questions.

BTW I had the same kind of problems getting my head around understanding
kamailio. I saw the potential but wasn't really understanding it. My
solution was to take the Kamailio Advanced Training https://www.asipto.com/sw/trainings/
