After the last tone has been played, base station starts again with the first tone. My phone also responds to a call, even if the tones cycle rather than sent simultaneously. -In this case the level of each tone is two times higher (+3 dB), but the peak level is two times lower (-3 dB) than the peak level of 4 simultaneous tones. +In this case the deviation level of each tone is two times higher (+6 dB). (The level transmitted is two times lower (-6 dB) than the peak level of 4 simultaneous tones. This may help transmitters with deviation limiters to make the phone ring.) Add command line option "-P 50" to send each tone for 50 milliseconds. Try something between 20-100 milliseconds, if the phone still doesn't ring. Be sure to check: Does your transmitter has enough frequency deviation (15 KHz is suggested)? Do you really send the correct number of your phone, check the frequencies of your phone and use "-D 0" option to see what 4 frequencies the base station actually transmits. -- cgit v1.2.3
