hello! yes i'm part of a thesis group doing a call accounting software, and we're trying to do it as flexible as possible in the sense that it could cater to almost all models of pbx systems, as for now, we are using Nortel Meridian as our test bed. My part as as individual only concerns the development of an application that gets data directly from the port and then throws it to the SQL server, so the parsing of the strings are done in the SQL side and is no longer my duty. i'l try using the code you gave it , THanks a lot! i think it would really help us. You raelly made my day! =) Thanks agian and more power.
