I've had this problem for a long time, but I've always set it aside...
It's kind of hard to explain, but here it goes:
I've got an ISDN service at the office.
( I don't know if this is standart but with this ISDN service we got : 2 ISDN lines)
We've got 2 phone numbers. The "main" phone is plugged at one of the lines and works great.
We bought an analog portable phone and wanted to connect it to the "main" phone so that when we received a call both would ring.
As it was analog, we connected our ISDN modem (Zixel Omni.net Plus) to the ISDN line (2nd line) and connected the portable phone to the analog output/input of the modem so that the modem would convert the signal.
Here's what's happening:
I can make calls with the portable phone and the number shown on the receiver is the "main" number, but when I phone that number, only the "main" phone rings
If I call the secondary number, only the main phone rings as well.
I know it sounds confusing but give me some feedback on what you need cleared up and I will try to do that.
Thanks in advance
