Could someone please provide me some guidance on which button module is compatible with which module IP sets? I keep ordering the wrong ones and apparently I'm interpreting the documentation incorrectly. Thanks In Advance.
. Attaching button modules requires the phone to be powered using a separate power supply.
If not being powered by PoE, these telephones do not support the former 1151 and 1152 series of Avaya single phone power supply units. Instead an Avaya Single Port PoE injector (SPPOE-1A) should be used.
Single Port PoE Injector (SPPOE-1A)700500725 (part code)
Or make it easier on yourself and order 'extension module (or whatever) for Avaya model XXXX' and let your sales rep / accountmanager sort it out.
If he/she sends te wrong stuff it's their fault and not yours....
