how can I get a dump of frames that asterisk is seeing on the receive side
of these channels? In the faxdetect app, the only difference between a
working conf and a non-working conf is a call to ast_answer.. which gets
translated to zt_answer. In zt_answer under SIG_PRI I see a call to
pri_answer which presumeably sends a pri "ACKNOWLEDGE" triggering answer
Leading me to believe that the Lucent switch is not sending early media.
Call flow is:
analog subscriber --> Bell switch --> Feature group D --> Lucent --> PRI to
Asterisk --> Asterisk
so it could be the lucent breaking it or perhaps even further back in the
call path. ugh. If it weren't for the bell switch I wouldn't care so much
about answer supervision, but an answer on a busy/noanswer is sent all the
way back to the analog subscriber.
