[Asterisk-Users] Cisco 7905G SIP firmware needed

[Andrea Frigo]

Hi,
    I bought a 7905G Cisco IP Phone and want to connect to Asterisk with SIP 
protocol, but can't find a way to download this protocol update from Cisco, 
Can anyone please help me?
Support the SIP protocol also the XML applications that I can use with SCCP?
What is better, try to configure 7905G as SIP or try to use SCCP with 
Asterisk?

Best regards,
