I have a brand new SPA112 and configured just enough to connect to my router and on to my VoIP provider - in genral all is working. I cna make calls and receive calls. However there is one problem. I have a Panasonic DECT phone and when I go off hook to make a call there is only 2-3 seconds of dial tone before fast busy/reorder.
I changed the dial plan on the SPA112 to include P9 hoping that this would force a longer period of dial tone but it had no effect what so ever.
I am baffled, nothing I do appears to change the timing here. I do not have any other phones to experiment with. If I plug the DECT straight in to a standard BT landline, I get a reasonable during of dial tone.
Any suggestions on how I move forward?
Many thanks in advance....
