We have recently got a VOIP phone for our home based business and are having some terrible trouble.
We keep getting constant calls from '1001' or 'test' or '2000001' and other iterations like these.
Some research has led me to believe these are called 'ghost calls'. I have spoken to my VOIP provider about this who advised that it is due to the ISP sending packets of data to my connection.
He also advised that I needed to speak with my ISP (Vodafone obviously) and they would, and I quote:
"You will need to contact them and explain that you’re using a VoIP service – They can then change the broadband operation onto a different channel within the settings of the router which will solve the issue."
Now I questioned this a little further to try and find out what these 'channels' were. He was insistant, that if I phoned vodafone techincal support and explained what I had to him that they would solve the issue.
I did try and speak to Vodafone who said they had no idea what he was talking about other than WIFI channels, which are obviously not going to solve the problem.
When I went back to my VOIP provider, the guy emailed back with the following:
"This is shocking – A VoIP provider wouldn’t know what channels ISP’s use. Each ISP have completely different set ups. It would be impossible for us to know what channel each ISP needs to use to prevent ghost calls.
I would suggest putting them onto a 3 way conference call with you and myself. I don’t know what else to suggest. Your ISP is causing it and should be able to resolve it. I’ve never once come across and ISP that doesn’t know how to stop the ghost calls on a VoIP service or what channel they need to switch the broadband operation to – Shocking!"
So I'm basically stuck. Our VOIP phone is all but unusable due to the (literally hundreds of) ghost calls we keep receiving. Does anyone know if this guy knows what he is talking about? Is there some magic switch at Vodafones side that can resolve this problem or else is there anything I can do at my end?
