Hello again :)
I found define PJMEDIA_SDP_NEG_PREFER_REMOTE_CODEC_ORDER and run-time method
pjmedia_sdp_neg_set_prefer_remote_codec_order() which solve my problem.
I call run-time method in pjsua callback on_incoming_call() as:
pjsua_call *call;
pjsip_dialog *dlg;
pj_status_t status;
status = acquire_call("ESip::on_incoming_call()", call_id, &call, &dlg);
if (status == PJ_SUCCESS) {
status = pjmedia_sdp_neg_set_prefer_remote_codec_order( call->inv-
>neg,PJ_FALSE);
if (status != PJ_SUCCESS) {
PJ_LOG(3,("ESip", "Can't set \"codec select\" from local side!!"));
}
pjsip_dlg_dec_lock(dlg);
} else {
PJ_LOG(3,("ESip", "Can't acquire_call!!!!"));
}
but when codec L16/8000/1 is set to highest priority my application in
windows crash when i call method:
pjsua_call_answer()
crash:
file: pool.c
method: static void reset_pool(pj_pool_t *pool)
line:246: block = block->prev;
local variables:
pool 0x00d45aa8 {prev=0xfeeefeee next=0xfeeefeee obj_name=0x00d45ab0
factory 0xfeeefeee {policy={...} create_pool=??? release_pool=??? ...}
factory_data 0xfeeefeee void *
capacity 4277075694 unsigned int
increment_size 4277075694 unsigned int
block_list {prev=0xfeeefeee next=0xfeeefeee buf=0xfeeefeee <Bad Ptr> ...}
callback 0xfeeefeee void (pj_pool_t *, unsigned int)*
it seems the object pool is invalid...
in linux i get error:

These errors occurred only when one side have disable L16/8000/1 codec. When i
enable codec and i set highest priority for both side it works.
some hint?
thanks
