Can't bind to a socket: var/run/rtpproxy.sock [Permission denied]

So I am wanting to run rtpproxy on RHEL 7.9. There is a problem with permission in var/run. Is there a way to change from var/run to var/run/rtpproxy/ ?

Because I am getting error
"Can't bind to a socket: var/run/rtpporxy.sock [Permission denied]"
and before this, I got a problem related to pid which is in var/run folder.

I tried to find a solution in internet, there is one site suggest to try running the packages from var/run/rtpproxy/ , but how?

Thanks in advance!
