Error when using free2.voipgateway.org

[TheNetStriker]

I'am trying to use sipcmd with the free2.voipgateway.org server using the following commandline:

sipcmd -u 123546789 -c mypw -P sip -w free2.voipgateway.org -x "c987654321;ws3000;vtest.wav;h"

I always get the error "OnReleased: reason: EndedBySecurityDenial". What could be the problem? Here is the whole output:

Old post, I know, but I have the same issue. I'm using RingCentral though. Did you ever figure this out?

I was able to resolve this by removing the "h" at the end and moving to CallCentric, though I'm not entirely sure if the "h" is needed just yet in my script. Regardless, from my standpoint, my issue is resolved. Hope this helps.

I also ran into this error and got a solution: When you have some/any virtual network interface(s) it will lead to this error.
I checked with ifconfig and after i.e. ifconfig docker0 down it worked.

After analyzing the debug opal logs with the -o option of sipcmd I think the root cause is, that sipcmd is sending requests with all available interface IPs to the sip server which then will cause "EndedBySecurityDenial". This will also happen if you specify the ip with the -l param (local address to listen on)
