Hi all! In my dialplan I've included variable continue on fail: <extension name="Dial Out SIP-M200 Mobile numbers"> <condition field="destination_number" expression="^(89\d{9})$"> <action application="export" data="t38_passthru=true"/> <action application="set" data="continue_on_fail=1,2,3,6,25,34,38,41,42,44,47,63,66,500,501"/> <action application="info"/> <action application="bridge" data="sofia/gateway/SIP_M200/$1"/> <action application="limit_execute" data="hash limit SMG-1016M 60 bridge sofia/gateway/SMG-1016M/$1"/> </condition> </extension> And if FS recieve from first gateway USER_BUSY, then FS try to bridge this call to another gateway. Although in line <action application="set" data="continue_on_fail=1,2,3,6,25,34,38,41,42,44,47,63,66,500,501"/> there is no code Q.850 = 17. How resolve this issue? -- Best regards, Vitaly Davudov "VIP-TELECOM-SERVICE" Ltd. ("ETERIA" Group of companies) http://www.vts24.ru
