I am trying to setup PLAR signalling in asterisk. I have modified the FXSLS TX bits in dahdi-base.c on line 2580, and I can make calls.</div><div style="color:rgb(34,34,34);font-size:13px;font-family:arial,sans-serif">

When I go 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.</div>
