Hi bulldog,
A warm welcome and thanks for posting on our community forums. Sorry to hear that we had installed a faulty adaptor when switching over to our new phone systems.
We're glad the 2nd engineer managed to get this issue resolved in a short period of time for you.
Unfortunately, sometimes we are not to know the adaptors are faulty until it comes to using them.
If you have any further issues in the future regarding the new phone service, please post back to us through this channel.
Kind regards Jodi.
