<div class="im"> Generic MFCR2 telco or carrier specs sometimes lacks a complete protocol specification.<br>
Register signalling maybe R2 (MF or DTMF) but Line signalling may not allways be digital R2 .<br>
While line signalling maybe offerred thru CAS state supervision (AB bits pattern changes<br>
or just A bit simulating open/close loop circuit or an e&m variant like traditional analog lines).<br>
Ensure you have MFCR2 Register & Line signalling digital E1 in order to be able to use<br>
OpenR2.<br>

Dear , all expert<br>
I have a problem with R2(DTMF) connection the solution is 1 port to Telco 1 port to NEC<br>
so the problem is NEC can't detect answered call to billing system and can't transfer the call from operators<br>
then NEC engineer said "that is the problem from polarity reversal" can anyone tell me<br>
how to configuration for polarity reversal in asterisk with Sangoma A102 ?<br>
<br>
