SIP/2.0 580 Precondition Failed - CME Outbound call

[markmarvinq]

Hi,

We are having issue with outbound call having Preconditioned Failed error. Inbound call is working fine.

Checked with our ISP but they are saying internal configuration. Please assist. Below configuration and attached logs

The provider needs to tell you what their SBC doesn’t like about your INVITE. The response itself just says “classification failure.” That doesn’t tell us what they expect changed.

[Roger Kallberg]

Not directly related to your issue, but these two dtmf relay options are for H.323, h245-alphanumeric and h245-signal, and as you use SIP these are not applicable. Recommend you to remove them.

As others mentioned, your ISP must tell you what they don't like with your Invite.
