Hi for All. I am trying to make multi-channel sip test (up to 500 separate calls) based on pjsipua. The media device for my task - third party device. I have a questions. - Can I make multi-channel sip test without media-device are included to pjsip? Is there simple way to turn media-device supporting off for this test? RTP address & port values may be constants for my test. - File pjsua.h are include the next text: ---- typedef struct pjsua_config { /** * 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; ... --- What is the reason that "max_calls" must be smaller than PJSUA_MAX_CALLS, which by default is 32?
