The Cisco SPA 525G is similar to the SPA 504G offered by Ooma except it connects via WiFi (it's also 5-line versus 4-line but that doesn't matter to me). WiFi connectivity is MUCH EASIER than running lines. I own 2 of these phones from RingCentral and we're looking to switch to Ooma business.
I work a few 3 miles from Ooma HG. Could Ooma could provision the for phones for Ooma business if I brought them over? Great phones. I'm happy to be a beta test customer.
