Remote Phones dropping off, NAT issue or PBX Config?


#21

ok, so I’ve got a pcap file and I can see in wireshark where the ports are changing which as you say indicates an issue. Unfortunately I don’t know enough to interpret the cause.

If you link it someone may analyze it, otherwise you can read up a bit on TCP connections (FIN/ACK/etc).


#23

well, let’s try both. What’s the easiest way to link the pcap to this thread?


#24

Joshua, what’s the best way to upload the pcap and attach it to this thread while I research?


(Joshua C. Colp) #25

I have no idea what people normally use, but there are numerous ways to share files on the internet - such as Google Drive.

after reading this post:

I set Asterisk Sip Settings > rtp keepalive from 0 to 30, then applied…

no change, extensions were still going unreachable. Then I noticed he said that he had to restart amportal after applying the setting so I issued a fwconsole restart and as soon as it finished a whole slew of extensions reported as now reachable…

Too early to tell if this is the solution but I’m watching it now.

capture.pcac file if anyone would be so kind as to have a look

the relevant extension is 232 and the time frame is [2019-07-31 12:14:53] to [2019-07-31 12:15:03]

still NG…

shortly after ext 218 went unreachable for 3 minutes:

Check UDP connection and / or SIP connection timeouts on your firewall. Also NAT timeouts.
