FreePBX inbound call issue
-
Worth watching Asterisk and the firewall to see if when their calls fail on inbound if there is any traffic going to you whatsoever. If Asterisk sees it but has an issue, that means that we can rule out network issues or provider issues and it is something with the PBX. But my guess is that the call never gets to Asterisk at all.
-
For the firewall side, the PBX is just running through an old Linksys router/Cable modem setup. I've checked through the router and modem and can't find any references to the trunk IP, just the routes from our static IP to the internal PBX IP. What could I be missing there?

Has it been rebooted since the change?
-
Yeah the router has been rebooted 2-3 times today. Trunk provider suggested that too - I've done reboots on it, the PBX and the gateway.
I did the "sip show peers" command and I only see the new IP in the list. Watched a call out and a call in (that worked right after) and everything looked in order as far I could tell.

Unlikely that something is wrong there. It is possible that SIP-ALG is activated somewhere and causing an issue, but this would have been expected to have already been an issue before the change if this was the case.
We don't expect that the firewall is set up wrong, only that it might be "confused" for some reason. Try restarting it. But take a peek to see if any ALG settings are on in there, and definitely set up the STUN settings on your phones.

It's watching it over time that might be telling.
-
Looks like when the call goes to a busy signal that it's indeed not hitting the PBX as I get zero incoming call info in Asterisk
I don't see any SIP and/or ALG type settings on the router. It's a Linksys WRT54G running Tomato 1.28
-
That's a start. I'd check the firewall and see if it logs any traffic when a call comes in from the trunk provider.

Not my doing, on my list to upgrade/replace..

Ubiquiti ER-L
$95, excellent quality.

Just noticed a line on Asterisk that says -
Got SIP Response 486 "Busy Here" back from <trunk IP>

Does that come up reliably when an incoming call has the problem that you mention?

That's the first one I've seen go through.. underneath that it has a few lines stating everyone is busy/congested at this time, dial failed due to trunk reporting busy, etc.
Update: Looks like that was an outgoing call. Incoming calls are going through right now as people keep calling out, which fixes the issue for a bit as stated before.

Alright I'm tired of dinking with this old equipment. My primary network is running on a Sophos SG 230 connected to fiber. No more Linksys, no more Comcast! If I'm going to fix this I might as well do it right.

We have great luck with Ubiquiti gear. Fraction of the cost of Sophos and I dare say, better quality.

I love Ubiquiti stuff. I built out our WiFi and our IP camera system using all Ubiquiti gear. Awesome quality and reliability for the cost.

I will say.. I like the Sophos box, but I hate the GUI and how "proprietary" everything feels. It's difficult to navigate and determine how to properly open ports, etc. for this to work. Still no outbound or inbound calling working.
-
So made some progress.. If I call OUT now to my cell my cell will see it. There is no ring from the internal phone and once connected there is zero audio. Still cannot call IN.
-
OKAY. So.. we are back to the original problem but I have fully migrated the PBX to the newer infrastructure PBX > Sophos UTM > Fiber vs PBX > Linksys router > Comcast Business Modem
I can call out, I have audio, but I can only call in for a short duration AFTER an outbound call is made.
