[reSIProcate] accessing headers parameters

[Gianluca Martiniello]

Hi,

I am trying to use resiprocate to implement a registrar server. I need 
to access various headers parameters (e.g. "expires" parameter in 
contact header) and I wonder if there is some way to get a parameter 
value from an header.

For instance, when I need to get the header contact from a sip message 
what I do is:

NameAddrs contacts = sipmessage->header(h_Contacts);

Is there a similar method to get the parameters associated to this 
header? Something like:

IntegerParameter expires = contacts.parameter(p_expires);


Thanks in advance,

Gianluca
