[OpenSIPS-Users] calling external command with sudo

[Dragomir Haralambiev]

I have figured it out after some struggling. Sudo won't work due to tty
requirement set by default in sudoers. So in order to be able to execute
sudo command we need to disable tty requirement for that particular user in
/etc/sudoers by adding:

Defaults:opensips !requiretty

(where opensips is the userid which opensips runs as)
