本文主要是介绍opensips添加离线消息功能，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
按照项目的需求，需要使用OpenSIPS的离线功能，现在将配置过程记录以备后用。
OpenSIPS离线消息功能依赖于msilo模块(http://www.opensips.org/html/docs/modules/1.11.x/msilo.html)
修改OpenSIPS的配置文件opensips.cfg添加
loadmodule "msilo.so"
#加载msilo模块
modparam("msilo", "db_table", "silo")
#配置离线消息存储的表silo
modparam("msilo", "db_url","mysql://opensips:opensipsrw@localhost/opensips")
#配置数据库路径
modparam("msilo", "add_date", 1)
#配置是否显示[offline message +时间]
modparam("msilo","content_type_hdr","Content-Type: text/plain\r\n")
#配置存储类型
配置路由部分：
#注释以下这段：
/* if ( !(is_method("REGISTER") ) ) {if (from_uri==myself){# authenticate if from local subscriber# authenticate all initial non-REGISTER request that pretend to be# generated by local subscriber (domain from FROM URI is local)if (!proxy_authorize("", "subscriber")) {proxy_challenge("", "0");exit;}if (!db_check_from()) {sl_send_reply("403","Forbidden auth ID");exit;}consume_credentials();# caller authenticated} else {# if caller is not local, then called number must be localif (!uri==myself) {send_reply("403","Rely forbidden");exit;}}}
*/#修改一下这段if (is_method("REGISTER")){# authenticate the REGISTER requestsif (!www_authorize("", "subscriber")){www_challenge("", "0");exit;}if (!db_check_to()){sl_send_reply("403","Forbidden auth ID");exit;}if ( 0 ) setflag(TCP_PERSISTENT);if (!save("location"))sl_reply_error();#增加部分--startif (m_dump()){log("MSILO:offline message dumped\n");}else{log("MSILO:no offline message dumped\n");}#增加部分--endexit;}#修改这段if (!lookup("location","m")) {if (!db_does_uri_exist()) {send_reply("420","Bad Extension");exit;}#从这里开始修改if(! t_newtran()){sl_reply_error();exit;}#以下为增加部分if (!method=="MESSAGE"){if (!t_reply("404", "Not found")){sl_reply_error();};exit;};log("MSILO:Message received -> storing using MSILO\n");if (m_store("$ru")){log("MSILO:offline message stored\n");if (!t_reply("202","Accepted")){sl_reply_error();};}else{log("MSILO:offline message NOT stroed\n");if(!t_reply("503","Service Unavailable")){sl_reply_error();};};exit;}t_on_failure("1"); #增加这句if (isbflagset(NAT)) setflag(NAT); #在配置文件最后增加：
failure_route[1] {# forwarding failed -- check if the request was a MESSAGEif (!method=="MESSAGE"){exit;};log(1,"MSILO:the downstream UA doesn‘t support MESSAGEs\n");# we have changed the R-URI with the contact address, ignore it nowif (m_store("$ou")){log("MSILO: offline message stored\n");t_reply("202", "Accepted");}else{log("MSILO: offline message NOT stored\n");t_reply("503", "Service Unavailable");};
}
到这里离线消息功能配置完成，为方便其他朋友，特意贴出全部配置文件(注意红色部分)
