Obi firmware bug
ProfTech:
My Obi 110 was crashing randomly and frequently until I put X_ProxyServerRedundancy back to it's Default setting.
Turning off ProxyServerRedundancy stopped it from crashing immediately.
My tests showed that it didn't matter if I used callcentric.com or srv.callcentric.com for the Proxy as long as whatever servers you are using send the "abbreviated" list of servers. Just be sure X_DnsSrvAutoPrefix is checked to get the benefit of their new server setup. Until [and If] Obi is able to make the DNS change for TCP that has been requested, it seems redundant Proxy Servers won't work.
Turning off ProxyServerRedundancy stopped my Obi from crashing immediately.
Be sure both X_ProxyServerRedundancy and X_SecondaryRegistration have Default checked.
*EDITED* I just remembered there was a note from Obi about the 2744 firmware for the 110 - Proxy redundancy fail-over then resume improvement... Something may have broke (or been made worse) with this Build. Haven't tried reverting to the previous build. I opened a ticket with Obi.

I saw the same repeated crash and reboot cycles on my Obi 100 and came up with the same solution. I was on an earlier firmware build and upgraded to the 2744 build to try to fix it (which it didn't), so I don't think it was something that 2744 introduced.

I have no idea why, but I have been using the setting recommended by CC (with X_ProxyServerRedundancy checked) for over 2 weeks without issue.

other than the X_ProxyServerRedundancy checked, they have changed the recommended settings twice in the last 10 days.

While that is true, there's also a lot of conflicting and overlapping info in their recommendations, current and recent.
For example they have step 1 as power cycle all hardware, double check firewall. As was pointed out on dslr, is this to be done every time you change dns settings?
Step 2 if current config works do not change anything, and then "**IMPORTANT: We recommend using DNS SRV Settings for all configurations that support them," yet just below that for the obihai settings the dns srv prefix field is not listed.
It also says for outbound proxy "callcentric.com OR srv.callcentric.com (You can use either server, please test and configure this setting accordingly)"
Then step 3 says use these DNS servers, . . . . then "*The above listed DNS Servers are suggestions that have been successfully tested. You can use any DNS Servers provided that they resolve our SRV Records properly." Exactly how do I know if my isp provided DNS servers resolve the SRV records properly, is that what is causing the intermittent issues on the Obi device?
