Hello,
We are using SIM900b for making speech calls.
S/W version is 1137B08SIM900B32_ST.
We have kept COLP = 1;
Call is established by using ATD command. (ATD<number> )
There is Ring on the number.
ATH0 command is send GSM Module to disconnect the call. But there is no disconnection on outside party (It keeps on ringing)
Above works OK if we keep COLP = 0.
