Have recently installed a KX-TDA15 system in UK. Software is basically as default on the maintenance console. Has 2 port ISDN card (3280/3283). ISDN2e installed line giving two lines simultaneously. However, from outside only every other call inbound is picked up. Every other call gives a no answer signal on the callers end. Cannot seem to work this out. Is it a software / system fault or is it more likely the actual lines. Bt charge £200+ to check the lines out if they are found to be OK. Hence, trying to make sure that I had not missed something !
