I have an original first-generation Obi110 which was in cold storage for several years. Previously it was used solely as FXS/FXO for a popular softpbx, which means that:
(a) It has never actually been connected to the internet (at least, not directly).
(b) Its networking parameters were a bit odd: It was configured on a /31 subnet, with the server running the softpbx (and ntpd) as the other host on that net.
(c) I really wish I could have saved the settings I had used. It took a huge time investment to get it working as my FXS/FXO, about five years ago. I did not post in the forum; now I see others are asking the same question. And it worked perfectly for that purpose!
Subsequently it was lovingly packed, padded and wrapped in plastic in a clean, dry container.
Today I needed to make it work in a hurry, with very different settings... and I can't get into the web admin panel! tcp/80 just times out. I tried:
1. Tinkering with my firewall on the connecting computer. I wasted hours thinking I was stupid enough to drop my own packets, before I realized the packets are actually going out on the ethernet interface.
2. Running tcpdump on the ether, which just shows my browser's outgoing SYN (no ACK, nothing else) on tcp/80. On other ports tcp/udp, it also showed the OBi actively trying to register with the softpbx, get ntp update, and send syslog messages (which I actually read).
3. Poking at it with netcat and tcpdump from a different computer running a different operating system.
4. Portscanning it, to see if I changed the web admin port. The pdf admin manual (OBiDeviceAdminGuide.pdf) shows a setting for "Web Server Port Number" on page 91.
5. Plugging in a phone, pressing ***, and trying to find a setting for web server port. The manual does not list one. I also wasted fifteen minutes blindly trying to find an undocumented setting under option 0.
6. Gritting my teeth and factory-resetting the device. Bye-bye working FXS/FXO! I don't even remember whether I backed up the config somewhere.
7. Registering for Obitalk (which I do not want) so I can get into this forum!
Even after factory reset, connections to tcp/80 disappear into a black hole.
By the way, after factory reset, setting up the IP address, subnet mask, and default route through the telephone menu was a bit flaky. Hard power-cycling the device made it accept the settings. Then... nothing!
FWIW this device has its original firmware, from the era when the Obi110 was first released. I am not interested in updating the firmware with unverified/unsigned binaries. But it is a moot point, because I *cannot* update the firmware when I cannot get into the web admin interface.
Specific question:
* Is there a menu option through the *** telephone menu for the web server port?
General question:
* Help! I don't even know what to do next to troubleshoot this thing; and I have already wasted all day on it.
Ok, that is not a question. But you understand my frustration. ;-)
Thanks for any tips.
