	That SW looks like a valuable service. What are the chances you could
code it into a module for OpenSER, so OpenSER could deliver both SIP and
IAX routing/proxying, without having to rewrite all common parts of
OpenSER to deliver its services to SIP? Also, OpenSER/IAX would make
calls with mixed IAX/SIP legs easier to manage. And there's probably
lots of performance optimization - not to mention deployment
optimization.
