本文主要是介绍rtpengine faq，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！

安装

我目前用的是debian11

cat /etc/debian_version，结果是11.8

我试过这样安装：

echo 'deb https://deb.sipwise.com/spce/mr11.1.1/ bullseye main' > /etc/apt/sources.list.d/sipwise.list
echo 'deb-src https://deb.sipwise.com/spce/mr11.1.1/ bullseye main' >> /etc/apt/sources.list.d/sipwise.list
wget -q -O - https://deb.sipwise.com/spce/keyring/sipwise-keyring-bootstrap.gpg | apt-key add -
apt-get update && apt-get install -y ngcp-rtpengine

改成11.2.1也可以，但是11.3.1则失败

至于debian12我还没来得及做测试

不改任何配置的情况下服务是可以启动的

systemctl status rtpengine

systemctl status rtpengine-recording

# 为了节省篇幅就不贴日志了

用下面的命令可以检查到是否启动了内核转发模块：

# lsmod | grep -i rtp
xt_RTPENGINE 61440 4
x_tables 53248 3 nft_compat,xt_RTPENGINE,ip_tables

rtpengine的配置

配置项目比较多，但可能比较难配置的可能是interface，下面是我的配置：

interface=priv/172.16.228.202;pub/172.16.228.202!113.113.113 # 1:1 nat

interface=priv/172.16.228.202;pub/172.16.228.202!113.113.113.113;inner/172.16.228.203 # double nic

interface=eth0

rtpengine-ctl常用命令（类似FreeSWITCH的fs_cli）

rtpengine-ctl list numsessions
rtpengine-ctl list sessions all
rtpengine-ctl terminate all

rtpengine-ctl是用perl写的，如果不想用perl，可以考虑用curl，使能rtpengine的http配置即可

关于录音

先看这个配置：

recording-dir = /var/spool/rtpengine
recording-method = pcap

这个够简单，rtpengine一个进程就搞定，但是需要后期处理pcap文件

再看这个配置：

table = 0 #必须大于等于0
recording-method = proc

并且录音（rtpengine-recording）要这样配置：

# rtpengine-recording.conf

table = 0 #必须大于等于0
output-dir = /var/lib/rtpengine-recording
output-format = wav
mp3-bitrate = 48000
output-mixed = true
output-single = true
output-chmod = 0660
output-chown = root
output-chgrp = root
mysql-host = localhost
mysql-port = 3306
mysql-user = root
mysql-pass = root
mysql-db = rtpengine
log-mark-prefix = «
log-mark-suffix = »
log-facility = local2

同时，需要创建mysql数据库rtpengine，并创建下面的三张表：

CREATE TABLE `recording_calls` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`call_id` varchar(250) NOT NULL,
`start_timestamp` decimal(13,3) DEFAULT NULL,
`end_timestamp` decimal(13,3) DEFAULT NULL,
`status` enum('recording','completed','confirmed') DEFAULT 'recording',
PRIMARY KEY (`id`),
KEY `call_id` (`call_id`)
);
CREATE TABLE `recording_streams` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`call` int(10) unsigned NOT NULL,
`local_filename` varchar(250) NOT NULL,
`full_filename` varchar(250) NOT NULL,
`file_format` varchar(10) NOT NULL,
`stream` mediumblob,
`output_type` enum('mixed','single') NOT NULL,
`stream_id` int(10) unsigned NOT NULL,
`sample_rate` int(10) unsigned NOT NULL DEFAULT '0',
`channels` int(10) unsigned NOT NULL DEFAULT '0',
`ssrc` int(10) unsigned NOT NULL,
`start_timestamp` decimal(13,3) DEFAULT NULL,
`end_timestamp` decimal(13,3) DEFAULT NULL,
`tag_label` varchar(255) NOT NULL DEFAULT '',
PRIMARY KEY (`id`),
KEY `call` (`call`),
CONSTRAINT `fk_call_id` FOREIGN KEY (`call`) REFERENCES `recording_calls` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
);
CREATE TABLE `recording_metakeys` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`call` int(10) unsigned NOT NULL,
`key` char(255) NOT NULL,
`value` char(255) NOT NULL,
PRIMARY KEY (`id`),
KEY `prim_lookup` (`value`,`key`),
KEY `fk_call_idx` (`call`),
CONSTRAINT `fk_call_idx` FOREIGN KEY (`call`) REFERENCES `recording_calls` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
);
