Heya Joy,
I tried OpenSER 1.3 4 months ago in a 64-bit architecture and i had too many
problems during compilation, or when ok, it crashes often.
I'd to turn back my project to SER (sorry Daniel ;), I didn't have time to
debug.
Then, Kamailio project appeared, and I use it in a 64-bit architecture now,
I didn't have any problems (compilation, ...).
All is fine, it works perfectly.
Maybe, just try it ?
.Sam.
