Hi all "The IP Phone 1535 videophone uses RFC 3261 compliant Session Initiation Protocol (SIP) to establish both voice and video calls. Connected to your local area network (LAN) through an Ethernet connection or by 802.11b/g wireless (WiFi) connection, the IP Phone 1535 provides extensive telephony services, multimedia tools, full video conversation functionality, an array of ring melodies, and a personalized display. You can also use the IP Phone 1535 to check e-mail, voice mail, or browse the Web. The IP Phone 1535 is designed for enterprises seeking a cost-effective personal video endpoint and is also ideal for tele working groups and multi-site companies who are seeking increased collaboration between sites.

I put this in here to get your opinion on the above phone, is it any good? and can I use it with 3CX? Any info would be gratefully received. Thank you.
