last week I spoke directly to Spectralink, because nobody at Avaya or Crane knew exately how the wireless solutions realy works. The SVP is between the IPO and the AP. The wireless phone talks to the AP, through the SVP to the IPO, so the 36XX never talks directly to the IPO (only when you boot the phone to dowload the required boot files like a regulair IP hardphone).
They said it was also requirred to have a SVP at each site where you want to run 36XX phones.....Don't know why....It has become clear to me that the 36XX solution is not for small numbers of users. Spectralink confirmed this.
I will ask the engineer today whe this is required...
