Hi, I am a US partner with 3cx and noticed the Gigaset N510 recently made the compatibility list for 3CX. Question is, will the N510 and Gigaset S510H PRO DECT handset work in the U.S. market with U.S. DIDS and 3CX 12 Cloud? We cannot seem to find any U.S. distributors of the Gigaset N510, except thru sellers on eBay and Amazon. Will this work no problem if we order the base station and handsets from the U.K.? Please let me know anything, thank you!
