Hello,

We are trying to achieve rtpengine HA solely with kamailio and rtpengine modu=
le.

In the following example call goes to rtpengine node 10.5.0.183:22222 and the=
n we stop rtpengine service on this node to simulate failure.
Client is triggering re-INVITE, but, apparently, kamailio sticks to initially=
 selected rtpengine, producing the following errors:

Hi Arsenijs,

the HA-Road to rtpengine is a bit tricky. One Setup could be:

rtpengine-node-1 with redis-server1/redis-db1 (active)
rtpengine-node-2 with redis-server1/redis-db1 (passive, rtpengine disabled).
Some magic (corosync/pacemaker whatever).

On failure of rtpengine-node-1, rtpengine is stopped.
Then *some magic happens* and starts your rtpengine-node-2 rtpengine
process.
On startup rtpengine will use the redis saved calls as its own.
That's the "simplest" way of HA i could found.

There is also a more complex way in rtpengine with keyspace notifications.
https://github.com/sipwise/rtpengine/wiki/Redis-keyspace-notifications.
I didnt finished that one for me.

Hi,

You have to move the IP address of the original rtpengine node to the "failov=
er" node also.
All of the virtual interfaces must exist on both nodes and you have to enable=
 non local IP bind support in the Linux kernel to achive this.

Regards,
Zoltan

Subject: [SR-Users] Cannot achieve rtpengine HA

Hello,

We are trying to achieve rtpengine HA solely with kamailio and rtpengine modu=
le.

In the following example call goes to rtpengine node 10.5.0.183:22222 and the=
n we stop rtpengine service on this node to simulate failure.
Client is triggering re-INVITE, but, apparently, kamailio sticks to initially=
 selected rtpengine, producing the following errors:

Hi, thank you!

Probably the subject of this email is slightly misleading, the actual issue t=
hat we have is that kamailio sticks to the rtpengine node selected in the beg=
inning of the call.
If rtpengine node goes down and there are active calls, kamailio continues to=
 try to communicate with it, when it is already inactive:

Hi,



You have to move the IP address of the original rtpengine node to the =E2=80=
=9Efailover=E2=80=9D node also.

All of the virtual interfaces must exist on both nodes and you have to enable=
 non local IP bind support in the Linux kernel to achive this.

Zoltan

Hello,



We are trying to achieve rtpengine HA solely with kamailio and rtpengine modu=
le.



In the following example call goes to rtpengine node 10.5.0.183:22222 and the=
n we stop rtpengine service on this node to simulate failure.

Client is triggering re-INVITE, but, apparently, kamailio sticks to initially=
 selected rtpengine, producing the following errors:

Hello,

you can play with the rtpengine module timeout parameter to get a faster dete=
ction of down rtpengine daemons.

https://kamailio.org/docs/modules/5.5.x/modules/rtpengine.html#rtpengine.p.rt=
pengine_tout_ms

If you have some other detection/failover logic, it could also just deactivat=
e the rtpengine on the affected kamailio services by RPC commands.

Cheers,

Henning

Hi, thank you!

Probably the subject of this email is slightly misleading, the actual issue t=
hat we have is that kamailio sticks to the rtpengine node selected in the beg=
inning of the call.
If rtpengine node goes down and there are active calls, kamailio continues to=
 try to communicate with it, when it is already inactive:

Hi,



You have to move the IP address of the original rtpengine node to the "failov=
er" node also.

All of the virtual interfaces must exist on both nodes and you have to enable=
 non local IP bind support in the Linux kernel to achive this.

Zoltan

Subject: [SR-Users] Cannot achieve rtpengine HA



Hello,



We are trying to achieve rtpengine HA solely with kamailio and rtpengine modu=
le.



In the following example call goes to rtpengine node 10.5.0.183:22222 and the=
n we stop rtpengine service on this node to simulate failure.

Client is triggering re-INVITE, but, apparently, kamailio sticks to initially=
 selected rtpengine, producing the following errors:

Please advise how it can be solved.

Hello,



you can play with the rtpengine module timeout parameter to get a faster dete=
ction of down rtpengine daemons.



https://kamailio.org/docs/modules/5.5.x/modules/rtpengine.html#rtpengine.p.rt=
pengine_tout_ms



If you have some other detection/failover logic, it could also just deactivat=
e the rtpengine on the affected kamailio services by RPC commands.



Cheers,



Henning

Hi, thank you!



Probably the subject of this email is slightly misleading, the actual issue t=
hat we have is that kamailio sticks to the rtpengine node selected in the beg=
inning of the call.

If rtpengine node goes down and there are active calls, kamailio continues to=
 try to communicate with it, when it is already inactive:

Hi,



You have to move the IP address of the original rtpengine node to the =E2=80=
=9Efailover=E2=80=9D node also.

All of the virtual interfaces must exist on both nodes and you have to enable=
 non local IP bind support in the Linux kernel to achive this.

Zoltan
