I've noticed there has been replies a month ago, I wasn't able to get back right away. I must had came a off a bit rough in a couple of those replies. However, I have been able to get the 3CX to work in the basic sense. I have been able to work a SIP Polycom to register better than the Cisco I had.
I got rid of a Cisco Router with CM router on eBay and I am still trying to get the other phones off my hands. All I can say for someone with a micro enterprise that Cisco is extremely complicated and I won't be able to recoup the losses on such a complicated system. (and boy do I say that - I thought i knew what I was getting intp.) If i have extra money, I may get a slightly older Avaya IPO because the skillset goes towards those types of systems for me. I may give Ci$co another chance...wait ten years to get a UC350 on a deep discount, it may just be another waste in the pocket for me.
