Hi everyone, I noticed the following in pjsua.h: /** * Maximum calls to support (default: 4). The value specified here * must be smaller than the compile time maximum settings * PJSUA_MAX_CALLS, which by default is 32. To increase this * limit, the library must be recompiled with new PJSUA_MAX_CALLS * value. */ unsigned max_calls; Why must max_calls be less than PJSUA_MAX_CALLS? And how much less should it be? If PJSUA_MAX_CALLS is 32, can max_calls be 31? Thanks!
