[reSIProcate] replaces in inbound INVITE

[Scott Godin <slgodin@xxxxxxxxxxxx>]

Hi Derek,

 

I see that the replaces header is handled, when a REFER is received and you use makeInviteSessionFromRefer to create the outbound INVITE request.  But how should an app use the DUM api to match an inbound INVITE that contains a replaces header?  It looks like the DUM will create a new Invite Session for this request, instead of "replacing" the old one.  If that's that case should an app then call findInviteSession(CallId replaces) to get the replaced InviteSessionHandle and handle the "replacement" from the within the application only.

 

There is a comment in the findInviteSession function:

   //486/481 decision making logic where?  App may not wish to keep track of

   //invitesession state

 

Can you elaborate on it?  What is the purpose of the 2^nd (int - 481) in the pair that is returned.

 

Thanks for your help,

 

Scott
