<div>I haven't noticed related to INVITE timers (such as the 408)
because I only make my client behind NAT to register and re-register

get this 408 you mentionned.</div>

Starting with 3.0, most of tcp parameters are changeable at runtime via
RPC (you can use sercmd):<br>

The initial value can be set via global parameters:<br>

Hi Pascal,<br>
<br>
sounds indeed interesting. :-) Perhaps a problem with the internal
timers.. Do<br>
noticed also other timer related problems, like for internal INVITE 408<br>
replies or similar?<br>
<br>
Cheers,<br>
