Modified the<br> switch case block to send calls to the correct part of the<br> signaling-handling state machine.<br><br> - For FGC-CAMA operation, the delay between called number ST and<br> second wink for ANI spill has been made configurable; previously<br> all calls were made to wait for one full second.<br><br> - After the ANI spill, previous behavior was to require a 'ST' tone<br> to advance the call. This has been changed to allow 'STP' 'ST2P'<br> or 'ST3P' as well, for compatibility with ANI-D.<br><br> - Store ANI2 (ANI INFO) digits in the CALLERID(ANI2) channel variable.<br><br> - For calls with an ANI failure, No. 1 Crossbar switches will send<br> forward a single-digit failure code, with no calling number digits<br> and no ST pulse to terminate the spill. I've made the ANI timeout<br> configurable so to reduce dead air time on calls with ANI fail.<br><br> - ANI info digits configurable. Modern digital switches will send 2<br> digits, but ANI-B sends only a single info digit. This caused the<br> ANI reported by Asterisk to be misaligned.<br><br> - Changed a confusing log message to be more informative.<br><br>ASTERISK-29518<br><br>Change-Id: Ib7e27d987aee4ed9bc3663c57ef413e21b404256<br>---<br>M channels/chan_dahdi.c<br>M channels/chan_dahdi.h<br>M channels/sig_analog.c<br>M channels/sig_analog.h<br>4 files changed, 88 insertions(+), 10 deletions(-)<br><br></pre><pre style="font-family: monospace,monospace; white-space: pre-wrap;">git pull ssh://gerrit.asterisk.org:29418/asterisk refs/changes/51/16151/5</pre><p>To view, visit <a href="https://gerrit.asterisk.org/c/asterisk/+/16151">change 16151</a>.
