I’m in the same boat as many other legacy Sonus customers. The lack of integration of new products like Roam and Move with our legacy S1 products is a betrayal of those loyal Customers that helped make the company successful.
I could understand Sonus developing S2 to take advantage of additional features that may not be available for S1 compatible equipment, but to not make them backward compatible at some basic level is either lazy or incompetent - the alternative, suggesting this by design smacks of a company seeking to generate future revenue from planned obsolescence rather than innovation.
Only option for me at this point is to take both the Roam devices back to the store and no longer consider myself a Sonus Customer.
