    I'm having trouble with some numbers with one of my VoIP providers. Of course I'd contact them, it's just that, everything works fine on that Trunk using Asterisk, I'm only having trouble with 3CX and only when calling certain numbers. So I went ahead, and disconnected the trunk from 3CX and connected it to my Asterisk test install, turned on sip debuging and tried to call, the call succeeded, and here is the output, cut when the callees phone started ringing:

    And I did the same on 3CX, log cut right after received error code 488:

    I went through both logs and found some differences in INVITES, at which messages are allowed and "Supported", but I have no idea where to go on from this. If one of you who has more knowledge than me at SIP could take a look, that would be great!

    Kind regards,
