 +==== Example of how to get a specific header value ====
 +Below shows you an ICM formula to get the header value for the SIP header "X-CardEasy-CID"
 +This approach works no matter how many sip headers you add (remember there is a lengthy limit)
 +If header is not the end one and there is more than one sip header CVP is getting - it will alwasy end with a '|'
 +But even if its the last one - and there is no pipe - it will then return the value **after("X-CardEasy-CID:",Call.SIPHeader)** - so this works and you just replace **X-CardEasy-CID** with the name of your SIP header.
 +I also recommend you use custom functions in your ICM script to get the SIP header values - in case your formula needs to be changed (but this one shouldn't).

 +<code>
 +before("|",after("X-CardEasy-CID:",Call.SIPHeader))
