**manual edit: /etc/rtpengine/rtpengine.conf: set your IPs.

If you want to add webrtc2sip feature use next lines

certbot certonly -d webrtc.domain.com

**manual edit: kamailiorc: uncomment db engine string

kamdbctl create kamailio 


download template kamailio.cfg, tls.cfg and kamailio_local.cfg 

(git clone https://bitbucket.org/erewin/webrtc2sip-template.git)

systemctl start rtpengine
systemctl start kamailio

To make the same on Debian 11

#!/usr/bin/sh
apt update
apt upgrade

#here you have reboot

Kamailio and Opensips

This is the list of completed solutions based on Kamailio\opensips.

KAMAILIO:

WEBRTC2SIP server – using kamailio + rtpengine, makes possible to use webphone based on webrtc to using common SIP servers

• transfer between SIP and WEBRTC protocols and vice versa.
• transconding g729 to g711

LoadBalancer – using only kamailio without DBs, makes loadbalancing between asterisks servers.

SBC – using kamailio and sql DBs for manage incoming traffic to asterisk, placed before asterisk on same PC.

• insert custom headers
• block hackers traffic
• manage CPS and monitoring tools
• control PDD of calls
  

OPENSIPS:

Redirect server – working with billing software JERA. Makes simultaneously outbound calls based on redirect messages from billing.

• control CPS for customers
• block unwanted traffic
• monitoring online calls with custom dashboard
• make CDRs for insert into billing

Failover server – makes possible to switch between 2 opensips servers without loosing online calls.

WEBRTC2SIP. KAMAILIO. RTPENGINE. CENTOS 7.

Полная статья по инсталляции webrtc2sip на centos 7 здесь. А тут видео.

В качестве основы эту статью и компиляцию вручную. В целом компиляция особых проблем не вызвала. Пакеты все которые надо ставятся.

Проблема возникла при инсталляции в качестве сервиса.

а) не стал разбираться с правами и запускаю от root,
б) необходимо убрать из rtpengine.services параметры из окружения,

Было:

ExecStart=/usr/sbin/rtpengine --config-file=${CFGFILE} --interface=${INTERFACE} --listen-ng=${LISTEN_UDP} --log-facility=${LOG_FACILITY} --log-level=${LOG_LEVEL}

Стало:

ExecStart=/usr/sbin/rtpengine --pidfile /run/rtpengine.pid --config-file /etc/rtpengine/rtpengine.conf --table 0

в) учесть имена pid файла, он должен совпадать в /etc/rtpengine/rtpengine.conf , /etc/sysconfig/rtpengine , rtpengine.service – последний файл можно найти командой systemctl status rtpengine.service.

Помощь с ошибками:

webrtc console:  Called with SDP without DTLS fingerprint. - для моей версии rtpengine, необходимо было использовать ICE=force, без этого флага rtpengine не добавлял fingerprint в SDP. возможно в новых версиях rtpengine всё уже в порядке.
