Just wondering if anyone else has had this problem or has come across this in the past.
I have a customer with a Samsung 7200 Officeserv PBX connected to an SPA8000. Randomly, every 15-20 minutes they will get a phantom call on their PBX from the Analogue Trunk port that the 8000 is connected to. I have checked to see if there is a problem with the SPA8000 by plugging in a standard analogue phone, however I was not able to replicate the issue. I have made sure that the Message Waiting and VM Notification is disabled. The rest of the config is pretty standard (Trunks not being used, registering by line and things changed were the Regional DIaltone settings). The only thing I could think of is a possible Voltage issue? The PBX seems to work fine on standard PSTN lines.
I've got version 6.1.3 on the SPA8000.
Does anyone have any suggestions?
