So I have recently moved over to BT business and use non BT voip services. I have recently been experiencing issues with receiving calls on VOIP lines. I have hardware voip phones and softphones and the problems occur with all. If I use a different network (I've tried 3G and local wifi hotspot) it works fine but not on the BT line. I have connected my laptop directly to the modem to rule out any router issues and it still did not work. I've not had any issues in the few years I have been using this set up, and it was working fine for a while on BT, it started intermittantly but now is completely not working. I'm now stumped as once I connected directly with the laptop there is very little else I can change from my end. Does anyone have any suggestions about why this might be happening? Could it be the standard BT voip package interferring or something?
