I have walked through this with multiple levels of support at OOMA. On the last support call we performed a test, I had one of the incoming numbers call my OOMA line so they could trace it. The tech said the call never reached OOMA, and there is apparently a network issue before it gets to the OOMA system. I had my sister - who is one of the bad numbers, open a ticket with her phone company, and they traced the call getting to OOMA. So obviously someone is not being honest here.
I have no idea where to turn next, other than to drop OOMA. Would really be interested in hearing any updates from OP.
Is it a voicemail greeting or some recorded message telling you about some routing issue (number disconnected, try again, circuits busy etc)? If voicemail greeting, does it sound like an Ooma voicemail greeting if generic? Have you (or your calling party) left a message telling the owner of the voicemail to call back? These problematic callers, do they all have the same service provider?thehip wrote:Since July, three of those incoming numbers can not get through to me. They go directly to some generic voice mail, but it is not my voice mail.
