Hi Bogdan,
Can add_rr_param be called from branch_route? It is needed for later
processing of re-INVITE.
If SDP is different for each branch, what would it be for the failure route
in a serial forking senario? Is the message reverted back to its original
content? That brings another question... can these functions be called from
failure_route?
Thanks,
Richard

Hi Richard,
to implement per branch NAT traversal, you need several thing,
additional to branch route:
- per branch flags - these are available in the current
testing/developing branch (cvs head) - see
http://www.openser.org/pipermail/devel/2005-September/000515.html
- nathelper/mediaproxy functions to be allowed to be called from
branch route - for the moment I see no problem with doing this, but I
will have to double check before setting proper function allowances.
regards,
bogdan

Hi,
I am trying to figure out how to use branch route for nat traversal.
If a subscriber registers from multiple locations, a branch route is
called after lookup. For example, if locations include UAs behind same
NAT and different NAT, i'd like to invoke any rtp/media-proxy
accordingly in branch_route[], . However they can't be called inside a
branch_route. What's the best way to do this?
Thanks,
Richard
