[h323plus] Regarding increasing the call capacity of H323plus

[Vlasis Hatzistavrou (KTI)]

Hello Simon,

After I compiled h323plus successfully I tried to have Asterisk's
chan_h323 built with h323plus.

I made the necessary changes in Asterisk's ./configure script in order
to reflect the library changes (mostly path changes).

The only problem that remains now is that the verification of the
H323plus installation fails, because the configuration script cannot
compile a small test program.

Here is the log from the configure:

The conftest.cpp is below:
*****************************
#include "ptlib.h"
#include "h323.h"
#include "h323ep.h"

int
main ()
{
H323EndPoint ep = H323EndPoint();
   ;
   return 0;
}
*****************************

Do you have any quick recommendations that I can try before I try to go 
through the H323plus library's code later tonight?

Best regards,
Vlasis.
