I've looked the sessions history for deepvox.cloudonix.net, from about that time, and it looks like most (all?) errors are sessions that report these errors:

• Outbound dial {CALLID} to {DESTINATION} has failed: 503 Service Unavailable
• No outbound trunk found to take the call to {DESTINATION} out of [33921831081561392.zt.plivo.com], last status: ERROR

Which explain the situation pretty well, we believe - the remote SIP service for the outbound trunk "33921831081561392.zt.plivo.com" has reject the call with the error "503 Service Unavailable".

This seems to be either a misconfiguration of the outbound trunk "33921831081561392.zt.plivo.com" in the the deepvox.cloudonix.net domain - i.e. it is not configured according to the how the termination service documentation indicated - or there's some misconfiguration on the termination service side.

Looking at the trunk configuration, it says that the trunk named "33921831081561392.zt.plivo.com" is using the destination remote host address "sbc00.in.dimi.tel" - you should check with the dimitel setup, that it is set correctly for your usage.

we are experiencing the same issues , could you please help we are unable
to make calls.
