SIP Trunk using Singapore Number with AVOXI cannot make Outbound Call

[hkgateway]

Hello, we are using AVOXI Singapore Number and cannot make Outbound Call. The Inbound call is right which we can answer call inside 3CX app when someone dial this AVOXI Singapore Number. But when we to make local Singapore number outbound calls through 3CX app, we received a voice prompt "This code number is not valid". There is also a event log "Call or Registration to 62255582@(Ln.10000@AVOXI) has failed. 199.244.96.40 replied: 403 Auth Failed; from IP:199.244.96.40:5060" inside our 3CX management console. This outbound call even not passed to AVOXI as no outbound log at AVOXI console. May I know how should I setup the outbound call procedure when pairing with AVOXI?

Thanks!

I would talk to your provider about the required format of the numbers they want to see from you. Obviously someone is receiving that call (I assume that IP 199.244.96.40 is theirs). And I assume that it is them sending you a recording. They would have to explain what a "code number" is.
