Modify SIP-Header "From"

[Michael Schmidt]

Hi,

I need to modify the "From" field in the SIP-Header.

The original Sent SIP Header look like this:

_________________________________________________________________________

The modified should look like this where the phonenumber of the From-Field is replaced to the phonenumber which is also available in "Contact"

How the SIP-Profile rule for this have to look like? Is it possible to save the phonenumber from the "Contact" Field into a variable and use it in the From-Field?

Here you go:-

request INVITE sip-header Contact copy "<sip:(.*)@.*" u01
request INVITE sip-header From copy ".*<sip:(.*)@.*" u02
request INVITE sip-header From modify "(.*)<sip:.*@(.*)" "\1<sip:\u01@\2"

This doc will help if you need to modify further

Hi Atul,

thank you for your answer. It`s not working because in the Contact there is not always the correct number.

In the Field "Diversion" there is the correct number but the internal one.

So the original Diversion looks like:

Diversion: "username"<sip:881777@10.40.40.41>;privacy=off;reason=unconditional;screen=yes

I need the last two numbers of this internal number and merge this with 02054878 in front so that the From look like:

From: <sip:0205487877@10.35.6.9>;tag=67AA226C-126B

Do you know the rule for this also?

Try this:-

request INVITE sip-header Diversion copy "<sip:(.*)@.*" u01
request INVITE sip-header From modify "(.*)<sip:.*@(.*)" "\1<sip:\u01@\2"
request INVITE sip-header From modify "<sip:(.*)(..)@(.*)" "<sip:02054878\2@\3"

I know this is quite old by now, but could you quickly go over what the modify does?  from what I can see, "<sip:(.*)(..)@(.*)" "<sip:02054878\2@\3" takes the original From - "<sip:(.*)(..)@(.*)" and adds 02054878 and the last 2 digits, and leaves the rest alone?

So if I had - 

From: " ROBERT AUSTIN" < sip:3303992@blah.blah.blah>

that would become

From: " ROBERT AUSTIN" < sip:0205487892@blah.blah.blah> ?  I am just getting the hang of this stuff and I have to modify my FROM, CONTACT, and P-Asserted-ID fields to show 10 digits instead of the 7 I am currently presenting.

Yes, I caught that in the above post from Atul, but not until after I replied, heh.  apologies.  I am going through it now.
