    Can I make an ESI IPFP3 V2.6 a basic SIP Phone

    I have a non profit customer client who has a bunch of ESI IP phones and they want to see if they can be flashed (broken) so they can be generic SIP handsets. They have a phone system that will support SIP phones such as SNOM, Polycom etc. Does anyone know if this can be done? If it can, how?
