I have spent the morning on this project, still without success.
When I saw the mail on the list tonight from "[EMAIL PROTECTED]" it finally dawned on me to try a CVS-revert and see what happens.
It turns out that solved the problem--I can't say when exactly the bug showed up, but I did fresh CVS builds a couple of times in the past couple of days and they *have* the bug.
I'm currently running CVS-09/21/03-14:44:56 and it works just fine.
I'm not smart enough to spot the bug, nor to even elucidate it beyond the bounds of "it breaks Grandstream phones." So I'll let someone else tell me whether/how to do a bug report.
I do know that in the future I will sure be quicker to suspect asterisk in this sort of an unexplained phenom; I lost two days on this, and nearly wore out the flash memory on my phone changing its configs and resetting it :-)
SIP trace of attempted call below in case it helps anyone.
Thx.
B.
