Hi,
PJSIP in the past had limitations on the max concurrent calls, etc. There were ways to overcome them by changing the source code. (e.g. http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2013-February/015721.html)
Do any similar tweaks need to be done to the bundled pjproject to handle high volumes of concurrent calls with Asterisk?
What (if any) are the current default asterisk 13 + pjproject audio + video concurrent call limits if using the bundled pjproject + asterisk patches as is?
Thanks in advance.
Regards,
IanG

The bundled defaults are already tuned for server type loads.  The MAX_CALLS and MAX_PLAYERS settings mentioned in that email don't apply to asterisk since we don't use those components.

Here are the setting we use (third-party/pjproject/patches/config_site.h).  The best optimization is the use of epoll instead of select which we automatically turn on if the OS is Linux.  It's hard to say what the actual call limit would be since it's dependent on memory, CPU, etc.  Technically, it would be 2500 based on MAX_HANDLES but with epoll in use, that number just controls the size of 1 array and can be easily increased with little effect on memory utilization.
