voip migration trials and tribulations

Well here we go again another install. I was asked to help with a VOIP migration and the first thing I asked was, “Do you have documentation? “ I was assured by the client that they had all the documentation and it would be there on the day of the install. I asked if they mind sharing it and they said they’re too busy right now. In my experience that raises a big red flag but I had to let that go.
I get there for the install and find out the documentation is out of date, and incorrect.
I suggested that the first thing we do is determine which lines were using which phone number. Since the old lines were standard of pots lines, I took the old analog phone, called my cell phone, and documented which line had which phone number. I then used some folder labels that I always carry around and labeled the physical lines with the respective phone number.
To me it seemed like a fairly obvious thing, but to my client they thought it was black magic LOL.
Needless to say, that I took the time to document the install with drawings, downloaded manuals, and some photos.
I will post more details as you go through the migration with my trials and tribulations and hope you enjoy it
