I have modified the FXSLS TX bits in dahdi-base.c on line 2580, and I can make calls. .sig_type = DAHDI_SIG_FXSLS, .bits[DAHDI_TXSIG_ONHOOK] = DAHDI_BITS_ABCD, /*changed by for PLAR*/ .bits[DAHDI_TXSIG_OFFHOOK] = (0), /*changed by for PLAR*/ .bits[DAHDI_TXSIG_START] = DAHDI_BITS_ABCD, /*changed by for PLAR*/ When I got to change the rx, its a bit more complex. I have learned from this list that dahdi_rbsbits() handles the rx bits, but my changes seem to have no effect. Does anyone have a good understanding of this function? I would appreciate any help you can provide. case DAHDI_SIG_FXSLS: if (!(cursig & DAHDI_BBIT)) { /*Dennis RINGING */ /*<----- I think this is checking if the state is different from a set value? needs clarification*/ /* Check for ringing first */ __dahdi_hooksig_pvt(chan, DAHDI_RXSIG_RING); break; } if ((chan->sig != DAHDI_SIG_FXSLS) && (cursig & DAHDI_ABIT)) { /*<------ Why is it checking DAHDI_SIG_FXSLS? do I need to modify this to be 1111 also?*/ /* if went on hook */ __dahdi_hooksig_pvt(chan, DAHDI_RXSIG_ONHOOK); /*<----------I think this is passing it to a function that reacts to the signal in this case the onhook signal?*/ } else { __dahdi_hooksig_pvt(chan, DAHDI_RXSIG_OFFHOOK); /* <------ same here but with the off hook? */ } break; case DAHDI_SIG_CAS: /* send event that something changed */ __qevent(chan, DAHDI_EVENT_BITSCHANGED); break; Thanks Dennis
