| Thanks for your reply. I didn't test all ports on each board. However, now I left office to up-country branch. So I asked my co-worker at office to test more port and some of them did ring. This is strange. I assumed that after master reset, every port should has same default configuration. My co-worker asked local Siemens PABX dealer but they didn't arrange schedule yet. They will provide software and teach how to use software. They told us that there should be a sequence to turn on/off ring but they didn't know it yet as they never configure this model. I'll ask my co-worker to try "do not disturb" code (*97 / #97) and will report if it works or not. |
