Jain SIP get user name

Question

I need to get the extension number from the "From header", I have tried everything but nothing worked.

Even tried to do:

byte[] raw = req.getRawContent();

And manually find the From and the number, But that returned null

What am I doing wrong? How to get that number

Answer 1

Get the FromHeader and then extract the information you need from it. For instance, if the extension is the user part of the URI:

FromHeader fromHeader = (FromHeader) req.getHeader("From");
Address fromAddress = fromHeader.getAddress();
URI fromURI = fromAddress.getURI();
if (fromURI.isSipURI()) {
  SipURI fromSipURI = (SipURI) fromURI;
  extension = fromSipURI.getUser();
}

Answer 2

Did you saw the javadoc?

The method getRawContent() return a message content as a raw byte array, or null if no content is set

Can you explain again your question? Maybe I can help you.
