Alert-Info SIP INVITE Header is not making it from my PBX through SBC to SIP Phone

[br1andy3]

Hi all, appreciate any help with this, could someone point me at either the script or settings that would be removing the Alert-Info Headers? I have removed SBC as the proxy and the Alert-Info headers are being passed as expected. Everything else is working with SBC, calls connecting internally and externally with great sound quality. I am using the alert-info headers to pass information for distinctive ring tones for inbound calls.

What you mean is that the SBC removes the Alert-Info, but you need it for distinctive ring tones?

Would you contact with support@telcobridges.com please? Send your signaling capture too. We would like to see your Alert-Info header parameters.

I am using the Alert-Info header to tell my sip phone which ringtone to use, that is what I meant by distinctive ringing. I am using the default setup of SBC recommended in getting started guides for integrating with Asterisk.  Since I am a new member to the forums I am not able to paste the packet capture as it includes links, sending it along to the support email address provided.
