(8xx?) >>> I ask my SIP provider to include more headers to show the real ANI? >>> What would that service be called? If it's anything like a PRI provider, I've been told they only way to get true CID, in those instances, would be to provide a 1-800 number (US) for them to call. Then you'd get correct CID, since you're paying for both legs of the call. I do not know if this holds true for a SIP provider, Doug -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- Check out the new Asterisk community forum at: https://community.asterisk.org/ New to Asterisk?
