Solid DWDM platform with great features and format.
Kontras
This company operates on a shoestring in the USA. Zero, sales support. No corporate branding effort. No actual office in the USA and the address on the US website was an executive office suite for which the lease had expired over a year before I joined the company. HR is outsourced for the US employees. The only US sales engineer resigned during my first month and was not replaced.
