I have two mobile sip phone (csipsimple app on android phones) and an analog phone plugged in an linksys spa3000. All incoming calls are directed to a ring group with every phone and a ring all strategy.
I would like the ring group to shutdown when no mobile sip phone are registered.
Thank you, I have never wrote any script and even if I think I understand what is ChanIsAvail and ExecIf I do not know how to write the script. What tuto would you recommand to learn how to write scripts for asterisk ?
I would recommend looking for a support forum for that product then. I know FreePBX has a forum at https://community.freepbx.org I have not heard of raspx.
