Dockerized VoIP Stack
Hello Everyone,
Does anyone have experience in deploying Kamailio, Asterisk and RTPProxy to
a dockerized environment with K8s?
In short, we are looking to deploy the following applications to our
Kubernetes environment to support a SIP based PBX for our company:
- Kamailio (Sip Proxy with DID and Outbound SBC Functionality)
- Asterisk Realtime (MariaDB Client, ARI)
- RTPProxy (To-be-Determined)
Has anyone been successful, or failed, in doing this? I would love to hear
from you.

I have not done this configuration, but from experience using Kamailio
and RTP Proxy, and a media server in PBX configuration, it is not
recommended to share the host with other non-voip applications.
The issue is variable latency of RTP streams caused by non-voip
processes bursting in CPU and disk I/O at inconvenient moments.
Kamailio on its own would have no issue. RTP proxy might be marginally
affected. I would have stong concerns about using Asterisk.

As an addendum, the issue with RTP Proxy will be if you use it voice
recording mode. Any competing disk activity that can affect RTP stream
forwarding is to be avoided.

Hi, sincerely I haven't any experience in this, but there is someone else
which has done something similar, here the presentation at kamailio event

Hello Jermey, we will have a dedicated host for the VoIP stack with
individual docker containers.
I really appreciate your input on the RTP and media handling. Does using
G729 not help reduce the size? We will go with the most efficient
compression.

What amazing input! RTP Proxy will be in a dedicated docker container with
its own volume.
