PJSIP pjsua_call_reinvite添加自定义字段

在调用pjsua_call_reinvite添加自定义字段时可以使用以下代码
pj_caching_pool cp;
pj_pool_t* pool;
pj_caching_pool_init(&cp, &pj_pool_factory_default_policy, 0);
pool = pj_pool_create(&cp.factory, “header”, 1000, 1000, NULL);

pj_str_t hname = pj_str(“Test”);
pj_str_t hvalue = pj_str(“111”);
pjsip_generic_string_hdr* add_hdr = pjsip_generic_string_hdr_create(pool, &hname, &hvalue);
pj_list_push_back(&msg_data.hdr_list, add_hdr);
