> It seems that even though after detecting polarity reversal on asterisk, Asterisk does not answer the call.
> On further debugging on the issue it seems that, if "answeronpolarityswitch" is set to "yes" and "callprogress" is set to "no" as soon as call is answered and polarity reversal is detected by asterisk, Asterisk change the call state to UP but actually doesnot sending CONTORL_ANSWER frame to core.
> Below is the code snippet in order to support the above statement:
>  8122                         if (p->answeronpolarityswitch &&
>  8123                                 ((ast_channel_state(ast) == AST_STATE_DIALING) ||
>  8124                                 (ast_channel_state(ast) == AST_STATE_RINGING))) {
>  8125                                 ast_debug(1, "Answering on polarity switch!\n");
>  8126                                 ast_setstate(p->owner, AST_STATE_UP);
>  8127                                 if (p->hanguponpolarityswitch) {
