[Freeswitch-users] Cordless IP Phone

Hi I have had great success using Yealink phones with Freeswitch and a customer has asked me for a cordless phone for their office. I want to ensure that they can keep as much functionality with a cordless phone as they have with the Yealink T28. I am looking at the Siemens C610IP phone but don't know how well it plays with Freeswitch. Can someone please shed some light on the Siemens phone or any alternative that you have successfully implemented. Thanks in advance
