Software: NEC UCE 2012 R2 OW5000 & TAPI Link OS: Windows 2008 R2 Server: Virtual I have installed NEC OW5000 & TAPI Link software per install guide. I start TAPIMGMT.msc to configure my lines and assign users to those lines. The application is being used for a PBX Operator center so any user can sit at any station. Because of this all users have to be setup on all phone lines. There are 38 stations. All 38 stations can be setup in the Telephony server. My problem comes in when I start adding all the users to each phone line. I can add each user to 14 lines. On the lines 15-38, Telephony server accepts the users but when I refresh or close out and reopen the users are gone from all lines but the first 14. Is there a limit to the number of users telephony server can accept? Is there a fix to allow users on all 38 lines? On a side note, this all works in Windows 2003 and NEC OpenWorX (very old version) TAPI Link software. I have talked with NEC support, they claim it is a Microsoft issue. They claim they have setup a server in thier labs and do not have any issues with adding the same user to more than 14 lines. I have reinstall Windows 2008 R2 multiple times. Each install has the same results. Any and all advice is appreciated. Scott

Thank you for your reply. I have that document and used it to install the software. I am continuing to push NEC but they say they have installed in their lab without issue. I have reinstalled Windows 2008 R2, OW5000, & TAPI link multiple times and have had the same results each time.Scott

Arthur, I am the developer now supporting the NEC TSP (original developer is no longer here). I have posted a question at https://groups.google.com/forum/?fromgroups#!forum/microsoft.public.win32.programmer.tapi but its not very active, so not sure it will get responded to, but have some questions for you here. The problem is when the customer tries to assign a user to the 15th Line, the mmc / TAPIMGMT.MSC console shows that it made the assignment, but the C:\WINDOWS\TAPI\TSEC.INI file does not have the addition of the 15th Line to the user. Then when you exit mmc / TAPIMGMT.MSC and get back into mmc / TAPIMGMT.MSC the 15th assignment is gone (I am sure it reads the tsec.ini file which doesn't have the assignment). It doesn't appear to me that this assignment of users to lines is done in the Service Provider code. At least I can find no reference to users or the Tsec.ini file anywhere in the code. So here is what I see: 1. We have 14 Lines associated to user Auby Taylor and the corresponding entry in tsec.ini looks like below: [*] TsecIni= [TapiAdministrators] SEDAPPSLAB\hfeng=1 [SEDAPPSLAB\ataylor] FriendlyUserName=Auby Taylor Lines=5,5,5,6,5,7,5,8,5,9,5,10,5,11,5,12,5,13,5,14,5,15,5,16,5,3,5,17 Our providerId is 5, and there are 14 Lines assigned to SEDAPPSLAB\ataylor user (each Line assignment appears to be ProviderId,LineId I guess, when I added the 14th assignment, the 5,17 got added to the end of the Lines entry). 2. The screen shot of the mmc / TAPIMGMT.MSC is shown below where 1025 is the 14 Line that was added (1026 will be the 15th we will attempt to add): 3. If you right-Click on 1026 and do a Edit Users and add Auby Taylor as a user to 1026, the Gui shows the assignment as shown below: But the C:\WINDOWS\TAPI\tsec.ini file still only has the 14 entries as shown below (the 15th for Line 1026 is not in the tsec.ini file). [*] TsecIni= [TapiAdministrators] SEDAPPSLAB\hfeng=1 [SEDAPPSLAB\ataylor] FriendlyUserName=Auby Taylor Lines=5,5,5,6,5,7,5,8,5,9,5,10,5,11,5,12,5,13,5,14,5,15,5,16,5,3,5,17 4. If you exit "mmc / TAPIMGMT.MSC" and then re-run mmc / TAPIMGMT.MSC the 15th assignment disappears as shown below: (won't let me add more than 2 images per post, will put in next post) I am sure that the reason the 15th assignment disappears is because its not in the tsec.ini file. I do not believe this User to Line Assignment is being done in the TSP code, but instead this all seems to be in the TAPI code itself that writes to the tsec.ini file. When you click on Configure Provider I can find all the TSP code that manages PBXes, Lines, etc, but this User to Line assignment must not be being done in the TSP provider. If it is then what APIs are doing this. Thanks for any feedback. -Don

Here is the image for #4 in the previous post where after re-running mmc / TAPIMGMT.MSC the 15th assignment goes away:
