Networking TDA-50 and NCP500

[Len10]

I apologize in advance for this exceedingly long post, but I wanted to provide as much info as possible. 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.

Yes, when you upgrade the software version you need to re-register with Panasonic. A PITA but it is what it is.

If the system is not registered your extension ports will not work.

Good luck.

Thanks phones001 for your response. I received a new DKEY-FR file from Panasonic, but it didn't solve the problem. I replaced the old DKEY-FR file and initialized the system. I assume that is the correct way to re-register the system. In order to isolate the problem I took a few additional steps. 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?

I think I may have discovered the problem, but not the solution. I am unable to forward calls of any kind from the TDA50. I can't even forward an internal call. Forwarding is set to "All calls". I have the COS of all extensions set the same. I have no internal or external blocking set. I've enabled "transfer to CO" and "call forward to CO."

I apologize for a somewhat misleading post earlier on when I used the term "forwarding" loosely. I was never able to forward the PS. Instead I set the intercept destination “when called party is busy," to the floating extension of an ICD group in the other office. This only works if the PS is set as the DIL destination of the incoming CO line or if the DIL is set to a local ICD group and the PS is its only member. Once I add a local extension to the ICD group the PS no longer rings the other office.

I tried initializing the system and started again with the default settings, but still no ability to forward. I then initialized the PBX with the old SD card (without enhanced features) and I'm still unable to forward calls. How is that possible? How can all features except forwarding work? What can prevent the forwarding of calls that I haven't touched on? Has anyone ever had this problem before?
