All, while doing some product research on the Cisco Unified Communications 500 Series PBX system I discovered that the product has been designed to also support the dual mode (wifi/GSM) Nokia handsets. The 500 series can be optionally configured with an 802.11g interface. Do any of the Nokia participants on this list know whether or not the Cisco Unified Communications 500 Series will also work with the SIP client that is contained in OS2008? Here for those interested is the url to the www page at the Cisco www site for the document that asserts support for the Nokia dual mode handsets: http://www.cisco.com/application/pdf/en/us/guest/products/ps7293/c1037/cdccont_0900aecd806a8a1e.pdf -- Best Regards, John Holmblad Acadia Secure Networks, LLC <mailto:jholmblad at verizon.net>
