The job of technology is to take a potentially complicated thing and simplify it. Some of us, reading this on our smartphone, laptop or even desk-top will still be able to remember when a mobile phone involved a shoulder bag with a battery pack the size of a shoebox. A complex bit of kit that didn’t always work. Now we make calls from the middle of nowhere using our watches. That’s technology.
So, what’s this got to do with “Taking a SIP”??Have you ever considered that whilst good old fashioned copper wire telephone technology was specifically designed to carry audio messages, digital comms were designed to carry data, not audio. With the forthcoming end of copper wire telecoms, all calls will be internet based, Voice over Internet Protocol (VoIP), and VoIP involves the use of technology to ensure that our to-and-fro conversations can be enjoyed as we expect them.
When technology goes wrong, it’s not always clear what the problem is. Have you ever experienced any of these?
·????????Problems getting through to the person you’re calling
·????????Problems with them not hearing you, even though you hear them
·????????Problems with an echo, or the line being fuzzy

·????????Problems with getting cut-off during a call
If so the technology that’s failing you is probably what’s known as SIP-ALG (Session Initiation Protocol – Application Layer Gateway, in case you’re wondering). The SIP part does what it says on the tin, essentially it corresponds with whoever you’re calling and sets up your call.
It’s the ALG element that can cause problems. What it’s meant to do is sort out any inherent problems your router may cause, but what it can often do is cause the problems listed above, so our advice is to disable it on your router.
How you do this will depend on your router, but it shouldn’t be too much of a problem. A good start would be to call whoever supplied your router and to ask them. Failing that you could try an internet search, quoting the name and model number of your router. And if that fails you may just need to replace your existing router with one that’s more suitable for VoIP use.
If you still have problems, you may need a better internet connection or a router that’s more suitable for VoIP use. Give us a ring and we will try and help.
