[SIPForum-discussion] some parameters in Record-Route header

[monica]

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
