Hello,
I am trying to configure my on-premise 3CX system to accept 800 number calls from our sip provider AT&T. Their system send 5 zeros plus the 800 to the system. (Example 00000800123456789@IP Address). I had the DID configure with *800 but give a fast busy. Wireshark shows the call rejected with 407 error. Please help.. Thank you
