It appears to just come back online without pulling anything. This phone works, so I’m hesitant to factory reset it, as any phone that is factory reset fails to restart.
So I think you should look to determine if the phone is pulling off any configuration from the server (of course, the configuration server could be a different box - maybe check your dhcp server to verify that it is not pushing out some different server)
On the pbx, do a command like: sudo ngrep host IP-ADDRESS-OF-CISCO-PHONE
(could use tcpdump: sudo tcpdump -i eth0 -s 0 -w cisco-date +%m%d-%H%M.pcap host IP-ADDRESS but then would have to view pcap file in wireshark after testing)
and see what traffic comes through after the cisco phone is rebooted. Hopefully something other than the SIP traffic shows up such as tftp or ftp to transfer the configuration files from the server. (I don’t know what protocols the cisco phones support for provisioning - at least tftp I believe). Could check what is actually configured on the system (ftp, tftp, might use http/https as well)
Alternatively, look through /var/log and see if can tell how provisioning is done from any recent log files - though that assumes the provisioning servers are set to be logging.
Or maybe just try doing:
sudo locate dialplan.xml # if locate is installed on the system and set to update the db daily OR
sudo find / -name dialplan.xml #but will be slow as searches entire system
This tells you that the provisioning mechanism is somehow broken. It could be something trivial like the DHCP server not providing the required option. Or, the guy who wrote the files could have erased them when he got fired.
To track this down, capture traffic at the phone when you reboot it. See what it’s trying to pull and why it’s not getting it.
In the meantime, if only a few international numbers are to be called, you could set up your outbound routes so numbers that the Ciscos can dial are mapped to the proper destination. Another option is to set up a DISA – users dial a code, get dialtone from the PBX and then key the international destination number. If only one or a few users need to call overseas, perhaps you have the budget to replace just those phones.
How would I go about capturing the traffic at the phone? Do you use Wireshark for that or do I have to be plugged into the phone itself when it boots. Forgive my ignorance on this, my experience with this phone system is minimal.
Only ways are to capture on the server side of the traffic, or - on the switch - put the switch port for the phone into a mirror mode so can capture the traffic on a different computer. (Assumes using an switch that is good enough to support this mode).
On the phone keypad, is there a way to get into settings? Might have a screen that shows you what server it uses for provisioning (if any). I don’t know if these old phones also have an internal web server to configure that way (like polycom phones do). Maybe on the pbx do: sudo nmap IP-OF-CISCO-PHONE
and see what ports are open on the phone, if 80 or 443, has a web interface.
At this juncture, I believe this may just be an either an outbound rule issue, or a trunk issue, as this was the source of my problem about a year ago. If you need me to post a screen shot of those settings, I will accommodate.
When I updated the extension in putty to the one I made, it flat out gets stuck at ‘registering’ and stays there indefinitely, I couldn’t dial out, even if I tried.
What do you mean? If you update an extension by editing /etc/asterkisk/extensions_additional.conf, that will get overwritten whenever you Apply Config.
I was suggesting creating a new extension and using a softphone to register and make calls. This bypasses the number formatting issue and allows you to confirm that your outbound routes and trunks are correctly set.
We don’t have any softphone software here, unfortunately, none that can dial out anyway, only internally. Again, this phone I’m using, and the other phone were able to dial out internationally once upon a time, about a year ago, not sure what has changed. Normal outbound dialing works fine, it’s only when we dial out internationally does it fail.
I’m not sure what I’m doing wrong here. I’ve tried to set up 2 of the soft phones you recommended, and I keep getting errors for passwords not matching. I’ve used the password for the PBX login and the data from the phone extension I’m using currently.
Sorry for the delay, I was off yesterday and I’m not permitted to work remotely most of the time.
