Reverse polarity over analogue trunks

[trond456]

I just asked the PTT for the reverse polarity service on the analogue trunks to avoid charging for the unanswered outgoing calls, parmeters below helped me to do this but the case now when make a call towards a site answered by Auto attendant the call disconnected,(calls not answered by auto attendant are successfully established)
ROCAP:ROU=4;
ROU SEL TRM SERV NODG DIST DISL TRAF SIG BCAP
4 0110000001000010 4 3110000000 0 30 128 00151515 400110000000 001100

RODAP:ROU=ALL;
ROUTE DATA
ROU TYPE VARC VARI VARO FILTER
4 TL11 H'0000A021 H'00000708 H'0000A015 NO


Is there any advice to modify the parameters above... and I will appreciate if there are parameters already tested with reverse polarity over analogue trunks...

the reverse polarity service - EOS or B-answer ? If EOS then VARO d6 and SIG d4 is wrong and if B-answer then the VARO d7 is wrong but SIG d4 ok.

Thanks, I just tried the parametes below and this seems fine

ROCAI:ROU=1,SEL=0110000001000010,TRM=4,SERV=3110000000,SIG=500100020000,TRAF=00151515;


RODAI:ROU=1,TYPE=TL11,VARC=0000A021,VARI=00000708,VARO=0000A055;

Thanks you
