Hello All, I am looking for some documentation or a little how to on Diversion Headers. Here is what I am looking to do:

Customer calls one of 7000 phone numbers listed in the Yellow Pages. Our call statistics provider receives the call, captures call statistics and then reroutes the call to a single uri with the original called number in the diversion header.

I am almost certain they are doing it this way to prevent a nightmare in their dialplan. The issue is that I need to convert that number in the Diversion header to "TO:user@sip-server". This way my servers know what app to run.

Is it as simple as "Diversion="?
Is there any documentation covering Diversions? I have looked but I don't know if I am looking in the right place.

Thanks for any ideas.
Perry

You can add/replace the Diversion header by DialPlan.

> Is it as simple as "Diversion="?
Yes.

Do you want to add Diversion header in INVITE request packets?
Do you want to add Diversion header in response packets?

Thanks for the response. That is great information. What I want to do is read from the diversion header in the invite and then rewrite the header so that what is in the diversion header is now in the To: section.

I am all set up to try some things out so I am going to work on in based on your info.

Thanks again,
Perry

After much reading and trial and error, I have finally figured this out. I would like to share just in case someone else is looking for this.

It actually doesn't have very much to do with Diversions other than the fact that they are a URI and I am getting the URI for Diversion and Replacing the URI for To.

Here's what mine looks like:

Hi Perry,
Cool! Thank you for the info.

Matching Patterns

$request = ^INVITE $geturi(Diversion) = sip:(.+)@(.+) To = sip:14045551212

Deploy Patterns

$target = %2 To = sip:%1@your-sip-server.com $replaceuri = true

This DialPlan rule can be used with any domain not only "Your.com".
