Default or?

Already have a very satisfying CISCO SPA former model, I wanted to set up 2 new VoIP lines with this case.
After attempting to join CISCO (far too complicated !!! barriers to reach the service seem overwhelming for a small client) and myself facing my ISP / VoIP provider, doing research on the Internet and tried to set the cheapest references (with the confirmation of the choice by the supplier of lines), I had to give. There was probably a problem with my camera but I had no way to be certain. When in doubt I preferred not to ask the exchange and tour'm SIEMENS me to a model for simpler settings and especially that worked a 30-minute setup.
When in doubt (but not original default standard) and make an average with another case a bit complicated commissioning but once configured works very well, I propose 3 out of 5 stars.
