Nope. I don't believe they're standardized.

 

That said, the spec is clear on what to do with parameters you don't
recognize. You leave them alone.

You keep them in the URIs you put into Routes based on Record-Route. For
everything but ;lr and the

transport-related parameters defined in 3261, these parameters are only some
element talking to itself.

They don't change the behavior of any other element in the network, and it's
required to give the thing

that put the record-route header value there exactly what it asked for back
in the Route header.

Hi All,
 
 
I find a sip package which Record-Route header is like:
Record-Route:<sip:139.24.125.12;lr;pm;n2>
 
I don't know what's the meaning of the parameters 'pm' and 'n2'. Does
somebody know these 2 parameters? 
Thanks.
 
 
Regards, 
monica
