I'm having a bit of a play with my Raspberry Pi model B and the incredible PBX (link). It's working pretty well. Normally I run my PBX in a VMWare VM which has been working fine but thought I'd have a play with this.It appears I've come across a strange issue. Asterisk stops accepting inbound calls after a period of inactivity (like 15-20 minutes). asterisk -r on verbose shows absolutely NO activity when attempting a call from my cell. I get a message saying "The party you are trying to reach is unavailable" on my cell.When this fault is 'active', if I make an outbound call from an extension registered to my PBX, it works fine. Then, for a short period I can accept some calls. Also if I restart the system or simply restart the asterisk service using "restart amportal" over SSH, it seems to accept incoming calls for a short period. It's almost as if asterisk isn't even listening for calls at all, and restarting/making an outbound call wakes it up for a short period.Any ideas on what this might be?
