Question

我成功完全从pjsip项目构建了样本vidgui。但是当我运行时，它无法登录到IMS服务器。服务器返回错误：

SIP/2.0 400 Bad Request - P-Visited-Network-ID header missing

以下是应用程序运行时的调试日志：

以下是有关pjsua_acc_config的代码：（SIP_USERNAME，SIP_PASSWORD，SIP_DOMAIN已使用我的IMS帐户信息定义）

acc_cfg.id = pj_str( (char*)"<sip:" SIP_USERNAME "@" SIP_DOMAIN ">");
acc_cfg.reg_uri = pj_str((char*) ("sip:" SIP_DOMAIN));
acc_cfg.cred_count = 1;
acc_cfg.cred_info[0].realm = pj_str((char*)"*");
acc_cfg.cred_info[0].scheme = pj_str((char*)"digest");
acc_cfg.cred_info[0].username = pj_str((char*)SIP_USERNAME);
acc_cfg.cred_info[0].data = pj_str((char*)SIP_PASSWORD);
acc_cfg.proxy[acc_cfg.proxy_cnt++] = pj_str((char*) "<sip:" SIP_DOMAIN ";transport=tcp>");

帮我修复此错误。谢谢！

我认为您正面临着一个已知的OpenIMS问题：P-CSCF正在4060收听，S-CSCF收听5060.您应该通过P-CSCF到达S-CFCS，但是您正在直接访问最后一个服务器通过连接到端口5060，然后，它会抱怨因为P-Visited-Network-ID标头（应该由P-CSCF添加）丢失。

我建议您将代理地址配置更新为：

acc_cfg.proxy[acc_cfg.proxy_cnt++] = pj_str((char*) "<sip:" SIP_DOMAIN ":4060;transport=tcp>");

再试一次。

希望这有帮助。
