Hi Rob, no I have not tried using the other phone port. I will give that a try. If the interferance is still happening what do you think it could possibly be? Is the actual crackling (interference) coming from the Hub 3 or the street cabinet or something on your end? If that makes sense.
Thank you for getting back to me about this issue, and I'm really sorry to hear that you're experiencing this problem when on calls.
Would you be able to reboot your Hub for me and let me know if we're able to run a line test on your equipment? This will only take a moment, but will disconnect your connection on the landline for a minute or two, so please let me know if we're able to run this test.
This may help identify any issues that are ongoing with your connection.
Please let us know if we can run the line test and I will keep you updated on the results.
