Add charge info to INVITE message

Hi,

 

our SIP provider requires to add the Charge info to our SIP INVITE message. I am trying to add the Charge info the all the SIP INVITEs sent to the SIP provider by sip-manipulation. I'm trying to add 5555555555@sip.com as charge info.

 

Here is the config I did but nothing happens.

 

 

 

sip-manipulation
name ChargeInfo
description AddChargeInfo
split-headers 
join-headers 
header-rule
name addCharge
header-name Charge
action add
comparison-type case-sensitive
msg-type any
methods INVITE
match-value 
new-value "<sip:5555555555@sip.com;user=phone>;noa=3"
last-modified-by admin@172.16.1.1
last-modified-date 2013-12-01 21:43:21

 

and I have set session-agent like this

 

out-manipulationid ChargeInfo

 

Thank you
