Mike and Ed you are both right. I worked for Lucent for ten years (before they went down the drink) and installed everything from a Spirit to a 5E. The partner is the best little system on the market. I would put them up against any system out there.
About a year ago I got a call from a friend that needed some help moving the phone system to their new building. Yep it's a Partner and I installed it 19 years ago. If someone is only getting 5-7 years from a partner system it was installed wrong. Check the grounding on the system, that is the number one thing that takes out the ports "BAD GROUNDING" Cheers
