482 Loop Detected Response from Flexisip Server Running in Docker on Register

[shivbuyya]

Hi,

I am running the Flexisip server in the Docker container, added the port mapping for 5060. But when I try to register from Android application it shows connection failed and in the Flexisip server running in Docker container I can see below logs:

Hi,
I guess the problem comes from a misconfiguration of Flexisip.
I can see that you use 192.168.1.15 a your SIP domain, so you should set module::Registrar/reg-domains to 192.168.1.15.

What probably happened is that the first REGISTER request did not enter into the Registrar module and went directly to the Forward module. Thus, the proxy received a second time the REGISTER request (hints: Max-Forwards=69 and VIA branch id) and tried again to forward it to itself.

Sincerely,
Félix.

Hi Félix,

Thanks for the response,
As per your suggestion I have changed reg-domains to 192.168.1.15, but still the same issue persists. Getting Loop detected error.

Please find my configuration file details:

#[global]
debug=false

[module::Registrar]
enabled=true
reg-domains=192.168.1.15

[module::Authentication]
enabled=false
auth-domains=192.168.1.15
db-implementation=file
file-path=/etc/flexisip/users.db.txt

Also I have tried to disable the Forward , in that case server crashes:

[module::Forward]
enabled=false

My Ubuntu PC(192.168.1.15), On which I have created a docker(172.17.0.2, this is the IP Address of docker) with port mapping 5060:5060.

Please suggest is this the right way to run a flexisip on docker?

MY PC(192.168.1.15) -Ubuntu PC

\ /
Docker(172.17.0.2) - FlexiSIP Server running here with configuration mentioned above. Port Mapping 5060:5060 is done while creating docker container.

Clients are trying to register using the IP 192.168.1.15.

It shows Loop detected.

Please find the attached Log file
log.txt

Kindly help, and suggest what could be the reason.

Thanks,
Shiv
