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?

Firewall / router 99% will be the issue

Chorus has spent $1.4 billion on making their xDSL broadband network faster and even more now as they are upgrading their rural Conklins. If your still stuck on ADSL or VDSL, why not spend $195 on a master filter install to make sure you are getting the most out of your connection?

maybe your registration timers are out, change them to 1800,or 3600 depending on what the system will allow.

If making a call fixes it the problem is almost certainly your registrations timing out which is either your registration times or your firewall.

I don't think it's the firewall since it works fine using PiaF which I previously ran as VMWare VM. Also my register settings are already at 180.

Here's my PEER registration settings (I copied them out of my PIAF box): port=5060

port=5060
dtmfmode=rfc2833
disallow=all
allow=ulaw&alaw&g722
registertimeout=20
regseconds=180
type=peer
fromuser=<REDACTED>; this is your VFX Number without the leading 0 i.e. 9950XXXX
host=pan.wxnz.net
insecure=invite,port
canreinvite=no
nat=yes
secret=<REDACTED>
username=<REDACTED>

Here's what the PBX shows when the fault is 'active':

incrediblepbx*CLI> sip show registry Host dnsmgr Username Refresh State Reg.Time
pan.wxnz.net:5060 N <REDACTED> 285 Registered Sun, 26 Jan 2014 14:44:52
1 SIP registrations.

The "reg time" it shows is always <5 minutes from the current time, but it's still not going. Will try reducing it further and report back.

Ok that didn't work. But it appears to be a SIP trunk registration issue. When I run "sip reload" it starts working again.

I'm assuming your box is firewalled off and port 5060 isn't exposed to the internet?

port 5060 is NATed from my external IP to my PBX's internal IP, with incoming connections only allowed from pan.wxnz.net.

Change that firewall rule to the actual IP address 58.28.20.150

DOes Asterisk still show registered when the issue happens?

And are you running pure Asterisk or a distro?

coffeebaron -- am explicitly using the IP

sbiddle -- I'm running Incredible PBX 3.11.8 (followed this guide here -- http://nerdvittles.com/?p=8178)

I've also made sure Asterisk framework & all add-ons are up to date using the module manager.

Is DNS configured correctly on the Pi?

Yes it is -- it's configured via DHCP and I've checked that resolv.conf contains my DNS server.

Does your router have any SIP capability? I would suggest using a port other than 5060 on both asterisk and on the outside - maybe 25060 or something, and see what happens.
