Re: [Users] Natping in "dispatcher scenario"

Helge Waastad wrote: 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:

- 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...
