I have recently installed NEC Aspire PBX in my company and analog phones are working fine. We want to install few IP phones for portability purpose. I have 4 factories within city (connected thru Radio connectivirty). I can give IP phones to other factories also if required. User can also move with his phone if required .
Please suggest if this can be done with this EPABX.. And which IP phone will be required to achieve this.
