Hi, I'm a french user of 3CX v14. An interesting feature would be a call cost management specified by Trunk and PSTN gateway. I'll explain. I've got 2 SIP Trunks accounts on 2 different providers. Additinaly I've my PSTN gateway. Each one have his own call rates. I created outbound rules in order to call to destinations with the lowest cost, but these rules allow to have dialing backup. ie : to call to France my outbound rule have 3 routes : - my PSTN gateway (only support 1 sim call) - a SIP trunk sich only permit out call (with low rates to France) - an other SIP trunk with higher rates but permit 3 calls unfortunately the call cost module only permits a global cost by prefix, if it could permit a cost by prefix and trunk it would be great, ie : for call prefix 0033 : cost for PSTN gateway is x,xx€/min, cost for SIP-Trunk-1 is y,yy€/min and cost for SIP-Trunk-2 is z,zz€/min. It would be although interesting to keep global cost rate, since some different providers have same rates for the same destination. Regards PS : please be kind, forgive me for any english mistakes.
