[asterisk-users] polarity reverse

[Alec Davis]

Does TDM800 with FXO ports work with 1.6.2?

You should have also got other 'polarity related messages' during the call
setup.
One in particluar which prints debug info when a DAHDI_EVENT_POLARITY get
fired.

Code below.
 
ast_debug(1, "Polarity Reversal event occured - DEBUG 2: channel %d, state
%d, pol= %d, aonp= %d, honp= %d, pdelay= %d, tv= %d\n", p->channel,
ast->_state, p->polarity, p->answeronpolarityswitch,
p->hanguponpolarityswitch, p->polarityonanswerdelay,
ast_tvdiff_ms(ast_tvnow(), p->polaritydelaytv) ); 

If it doesn't work with the TDM800, file a bug report.

Alec
