Cisco 7941G VoIP SIP Firmware Testing

This is the process to display how easy it is to convert and configure a Cisco IP VoIP phone from the proprietary SCCP firmware to SIP firmware. This process must be used when attempting to use Cisco IP phones on popular VoIP systems like Asterisk and 3CX IP PBX systems, instead of Cisco’s overpriced CallManager software. Piece of cake if you ask me 🙂
