Telephone sytem faulting
I can fault most types of home telephone installation and if I haven't come across yours before I am sure that I have a contact who has. As for business phone systems I have lots of experience of Avaya or Lucent Definity and would be able to help with most problems. As for other systems I don't mind discussing them with you and I would certainly take a look for no charge and let you know whether I can do anything to help you.
