Adding a Diversion Header to Outbound Invite

Adding a Diversion Header to Outbound Invite…

Can someone tell me exactly how and where to add a diversion header to the invite I send to my provider?

In order to block my outbound caller ID I attempted to send “Unknown” in the from field but was instructed I would need to add a diversion header so that their SIP server will authenticate my outbound Invited based off the diversion header but send the from field for outbound caller ID.

I had tried to add it in the extensions.conf file but it is not coming across in the Invite my provider receives

Thanks

Hate to send anyone to the lime green site, but you might find this discussion at least informative, if not exactly helpful… http://is.gd/hkED
