Whenever you reach a dead end, use it to compare CUBEs behavior with another device.Īs opposed to registration, authentication is actually a method that ITSP uses to verify your identity.Įssentially, it uses authentication to decide whether we are allowed to make this call. Using a simple softphone is also great for troubleshooting a lot of other CUBE problems. Watch the differences in the SIP headers to understand what went wrong.

If you manage to register with your softphone, it means that the ITSP is at least doing something right, so open your Wireshark and compare the SIP messages from CUBE registration attempts with the ones generated by your softphone. Personally I use MicroSIP but there are many other options. The softphone will then automatically apply this info into the SIP messages.

The advantage of it is, that usually these softphones only require the most basic info like username, password and domain. Although not the most uplifting thought security wise, it means that if everything you try fails, try and register a softphone with the ITSP using the same credentials. Remember me mentioning in the beginning that dynamic registration to ITSP can help us with our troubleshooting? We'll, I wasn't lying!ĭynamic Registration means that you can actually register to your ITSP from every device who has the right credentials. It should put you back on the right track.

Watch the response code from ITSP to understand the reason for the failure. Run both of the command below to see CUBE registration attempts: If our first attempt was unlucky we would need to understand why. Line peer expires(sec) reg survival P-Associ-URI The first step would be making sure we are not shooting blanks!Įasiest method to verify that we are indeed registered to our ITSP is running: CUBE#show sip-ua register status

Parameters required:ĭo note that these are the parameters required for registration alone. This is obviously a great advantage for the ITSP, but we can find it handy as well, as you'll notice in the troubleshooting section.Įnough said, let's get to work. That's what registration is for, to dynamically manage the location of each customer's DID. In most cases, ITSP does not statically configure your CUBE's IP Address in their systems to send you the SIP traffic. It's just like registering your name with your home address so that your bills will come to the right place. Simply put, registration is there for the ITSP to know that you are alive and kicking and more importantly, where to send your incoming calls. Let's see what they are all about.Įver wondered what registration to ITSP is really for? Well, I did, and to be honest, too late for my own good. Mentally note that these are two different concepts with different roles. The bare minimum that we have to discover is the ITSP's approach to registration and it's approach to authentication. So, if we don't want to spend the night chasing ghosts, we have to ask the right questions! Well yippiee ki-yay!! Didn't I just win the lottery!!Īt times, it felt like it would be easier to extract information from a spy. The hard truth is, more often than not, the customer mails us this poor scanned fax that he received from the ITSP, which usually includes three lines: username, password and IP address. In this post I'll cover the CUBE Registration and CUBE Authentication concepts as they are the core of our communication with the ITSP. Fortunately, these problems are solvable, as long as we understand some basic concepts.
