Does anyone else find it interesting to have the ping also relayed via the OBP? If not, I just have to move the registrar more towards the frontend.
We ended up in implementing a simple stand-alone natping application for a proof-of-concept design using raw sockets for spoofing the OBP address, mainly for two reasons:
nice idea :-)

- Performance: a possibility would be to evaluate the Path uri in the
registrar and send a sip-based nat-ping (OPTION) with a pre-set route, but this would really stress the OBP (assume you've to ping 50.000 UACs every 60 seconds).
- Simplicity: it would require quite a lot of changes in
registrar/usrloc/nathelper/mediaproxy, so we just query the received-column of usrloc from the external natping application(s) and send empty udp packets.
Patches to the registrar and a new path module for accomplishing this (inserting proper Path headers in an OBP, and taking the received-address from a Path uri parameter and saving it into usrloc in a registrar) will be contributed the next days...
