Gene,

Can you please post your diffs to this mailing list as I am investigating these issues too.

Thanks a million.

Kind regards,
Frik

Ahh, now I realize where this bug came from; it was the change to
eliminate the dual-ringing issue on outgoing calls.
I think Mikael's patch makes sense: Does it solve your problem, Gene?
    

I'm not using iaxcomm any more so I can't test Mikael's patch in practice, 
but in principle it would have solved my problem as it occurred with 
incoming calls only (if memory serves). If Trevor can vouch for it then it 
is probably good to go.

I've actually written my own softphone code that uses iaxclient and in the 
process have hunted down and fixed (I think) about a half-dozen memory leaks 
in iaxclient. I'm happy to share the diffs but am not sure what the best 
approach for that is: I can post them to sourceforge or can send them to the 
list. Really, I'd like someone more familiar with the library to review the 
fixes for sanity. Steve, are you the maintainer of the iaxclient code? I'm 
sort of new to the open-source development model so I'm not sure what the 
most compliant contribution process is.

I've also been playing extensively (but less successfully) with the 
jitterbuffer/native transfer issues I was having and wrote about a couple of 
weeks ago. I narrowed down the problem to the fact that negative timestamps 
were being improperly handled by the new jb code but changing all the 
timestamps to unsigned values created another problem (audio becomes one-way 
after exactly 2^17 ms had elapsed on the call). I've gotten native transfers 
working beautifully but only if both the old and new JBs are completely 
disabled. Maybe I will tackle this more earnestly (and ask more questions 
about packet timestamps) after I submit my memory leak fixes.

Best,
-- Gene
