[reSIProcate] How to extract parameters from Contact Header?

Title: How to extract parameters from Contact Header?

I have the following Contact header:

Contact: <sip:1000@xxxxxxxxxxx:5060>;video;audio

I need to test whether the “video” and “audio” parameters are present.

How do I do this with resiprocate API?

The Resip Overview document describes how to get the individual contacts via:

for (NameAddrs::const_iterator i = msg->header(h_Contacts).begin(); i != msg->header(h_Contacts.end(); ++i){

    const NameAddr& na = *i;

    ...;

But, how do I get parameters from the Contact line?

TIA!
