I’m trying to network two phone systems (an NCP-500 and a TDA-50). I have the software upgrades for both systems(KX-NCS3910- KX-NCP and KX-TDA5920- KX-TDA50 CTI). A VPN has between setup between the offices. I need certain incoming CO lines at each office to ring at both offices simultaneously. The problem is only incoming calls to the NCP-500 are ringing in both offices. Calls to the TDA-50 are not ringing in the other office.

At each office I programmed a virtual PS that is forwarded to an ICD group at the other office. The phones are programmed using the extension method, not the PBX code method. All extensions in one office are in the 100’s and the extensions in the other office are in the 300’s. The floating extensions of the ICD groups start with a 1 or a 3 depending on which office they are part of (not in the 600’s as set by default).

Any extension in one office can call an extension in the other office, so I assume I set up the tie tables properly. NDSS buttons in both offices are working. As stated above, calls to the NCP-500 are being forwarded properly. I programmed each system the same way, including the COS of each virtual PS. A tech support specialist from Panasonic reviewed the DSSYS files from both systems and said it should be working, but offered to suggestion for resolving the problem.

The following information may be of diagnostic value. If I call the virtual PS(of the TDA-50) from an NCP-500 extension I get a busy signal. If I set the intercept destination “when called party is busy," to the NCP-500 ICD group it does work for internal calls. The NCP-500 ICD group does ring when the PS (of the TDA50) is called from an NCP-500 extension. It does not, however, ring at the office with the NCP-500 when the call to the TDA-500 is an incoming (external) call.

When I first programmed the NCP-500 only internal calls were forwarded by the virtual PS. Once the software was upgraded to the enhanced version, external call were also forwarded. Is it possible I don't have access to all the enhanced features of the TDA-50?

I think I upgraded the TDA-50 properly. I replaced the SD card with the new card that contains the enhancements and initialized the system. I then transferred the DSSYS file that I saved from the old card. I was prompted to transfer the DKEY-FR file when the system was initialized. The message indicated a flash ROM ID and a confirmation code ROM ID which were the same as when the system was initialized for the first time. I used the same DKEY-FR file I had when I first initialized the phone system. Is it possible I need a new DKEY-FR in order for all the enhanced features to work?

Any help would be much appreciated.

In order to isolate the problem I've tried to simplify the problem. If I forward a virtual PS or a wired extension (of the TDA-50)to my cell phone, it will only forward internal calls (extension calls from either office). I can't forward external calls. This eliminates the possibility of a networking problem. I have "transfer to CO" and "forward to extension" enabled. I still can figure out why external calls can't be forwarded? Has anyone had this problem before?

Class of service set.
Calls forwarding via VM? If so transfer should be unsupervised.

Thanks for the reply. There is no voice mail connected to the system. I have a TVA50, but I was waiting to install it until all the current issues have been resolved. COS should allow forwarding by the virtual PS. I have the COS set exactly like I have it set on the NCP-500 and that is working fine.

Are you doing a Supervised CO transfer or Dial ext and hangup?

I'm not sure I understand. I want the call forwarded (so it rings the ICD group and an outside destination simultaneously) not a call transfer. Call transfers are working properly.

That requires Advanced Software.

Just saw you have Enhanced SW.

If you want the ps/cell to be a menber of the ICD Group,
that only works with PRI, unless it has been changed from the last time I set it up.


See NOTEs on PSCNA website
I would think who ever sold you the SW would have told you.

If I set the DIL destination for the incoming CO I want to ring in both offices, the call doses get forwarded to the other office. If I set the DIL destination to the ICD Group's floating extension, it doesn't work. The manual states "ELCOT/LCOT CO lines and channels of a T1 CO line set to LCOT do not support this feature." I'm not sure what a "ELCOT/LCOT CO line" is?

I wanted to clarify my previous post. If I set the DIL destination for the incoming CO to the virtual PS, it does forward the call to the other office. If I set the DIL destination to an ICD Group's floating extension (and make the virtual PS a member of that group), it doesn't forward the call to the other office.
