| Hmm, i'll try this maybe i will get lucky. The DSS button is a good tip!
I've called the ISDN line with a ISDN phone from a other line that is not attached to the pbx. Unfortanately i can't use the isdn phone on the internal ISDN lines since the internal lines do not privide power over isdn.
I know the ISDN device should ring if the line ringes. Even when it's a voice call. It just doesn't pick up the line when it's a voice call (At least that is what is does directly on a 'normal' ISDN line).
Thanks for the tips. |
