never used DID Logic before. I purchased a 03 UK-wide national DID number from DID Logic. I created a SIP account on DID Logic and forwarded the 03 UK-wide national number to SIP Device. (really not sure if i need to forward to SIP device or SIP URI) Is that all i need to do in DID Logic? next step, i added a new VOIP Provider in 3CX using the built in DID Logic template. the built in DIDLogic template leaves the OUTBOUND PROXY blank - is this correct? My trunk is registered in 3CX i have an OUTBOUND rule with a simple 9 for prefix (im hoping if i press 9 then all calls will route over didlogic) when i dial out i see this message in the log file; 07-Aug-2015 12:26:23.851 Leg L:556.2[Line:10001>>99975378] is terminated: Cause: 404 No destination/INVITE from 18.104.22.168:5060 any help appreciated.
