Jain SIP get user name

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

Solution

  • 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();
}
