Hello,

I am new to this Community and hope that you can help me to solve my problem with the TDA200 : )
I used the search function and read almost every thread about the tda200 and I have not seen any problem like mine.

Setup:
TDA-200
Model No.: PSLP1207
Around 50 telephones (e.g. KX-T7665)
Line: ISDN

Problem:
Incoming calls from certain numbers are manipulated.
E.g.: We receive a call from the number 0751 #####, the display of our office phones show 07751 #####. So somewhere a digit is added making it impossible to use the recall function.
Since a few days the same thing happens with calls from other numbers. 0407 gets changed to 04407.

I could not understand where this is coming from. I checked the Caller ID Modification, but then read that it would not matter, since we are using ISDN. The CLIP modification does not seem to be misconfigured as well.
I used the "ISDN Protocol Trace" and logged an incoming call from the above mentioned number. In the log the number was 751 #####, the display still showed 07751 #####.

I am stuck right here and have no clue where to look.
Any help leading towards a solution is appreciated.

Thank you very much.


Greetings
Mark


(Sorry for any mistakes or unclear phrasing. English is not my main language.)

If it coming in correct on the trace then the system must be adding it
It is unusual to add a number second digit in. There must be something on the modification table for national numbers

As mentioned above, the Modification Tables seem to be irrelavant since we are getting the CLIP via ISDN. I checked the tables anyway and they are all empty.

Have you checked all four table modifications (1, 2, 3, 4)?, In all three tabs (Leading digits, Length of Digits, CLIP)?
