Hi Bruno, well last year i had the same problem, it was posted here. My solution was modify the source, inside isup.c you need modify the code, find this function static FUNC_SEND(backward_call_ind_transmit) and add some lines. I think Matt was going to setup an option..anyway here is the code static FUNC_SEND(backward_call_ind_transmit) { unsigned char alwayscharge= 2; parm[0] = 0x40 | alwayscharge; parm[1] = 0x14; return 2; } Regards Jorge Valencia G.
