Urgent 403 Error

[harrycarnaby]

Hi All
I have several SIP Trunks one one system and one of the SIP Trunks when dialing out on the 3cx app immediately says "Calls are forbidden by administrator"
Racking my brains as to what this can be, if anyone could help I would be greatly appreciated as my other SIP Trunk lines are fine.

The SIP is provided by Sipgate

Hello,

Is the destination country for it permitted? Outbound rules for that Trunk double-checked?
