Hi I am using sanghoma gateway to use 3 cx for my pstn line. I face a lot of problems, NBE crashes, when the call limit is exceeded Sanghoma crashes all leading to outage of more than a day. Is there an alternative to it. I find bero and patton gateways, but they are of relatively different technology. Which one is easy to maintain for a non techie... What is the difference between a Songhoma and a Bero / Patton,. Can someone get me URLs to the same.
