Obi100 dropping sip registration
chunkylover:
Currently IPSP-A is on google voice
IPSP-B connects to my FreeSWITCH server.
Obi100 behind a Tomato-VPN router (port forwarding disabled [because it didn't help]). It's registering fine on an initial boot, but there's some weirdness.
FreeSWITCH is configured with a sip registration time of 3600 (as is the obi100). FreeSWITCH status shows the registration expire time is always 120 seconds max (it doesn't do this for any other device).
SipDroid stays registered and works fine behind the same router.
What happens is, it registers fine initially and reregisters every 30 seconds (this is good). After some period of time, it fails registration. The FreeSwitch folks thought this might have something to do with the nonce.
Trial 1: 14:54:32 registers - 14:59:05 fails
Trial 2: 15:42:22 registers - 15:46:44 fails
I've tried STUN and ICE as well to no avail.
Advice?
here's a siptrace:

jjdeluxe:
I have the same problem. initial registration works, then within a minute or two, drops.
chunkylover:
There is a bug in the Obi Firmware that prevents the no-once from changing as it should. This has been resolved, in an unreleased firmware version: 1.2.1 (Build: 2196M7C9DCA28)
I'd share the firmware but it was pushed to my device, and this not being an open source product, I'm not sure how to get it *out*, or if it would even be legal to do so.
Email support@obihai.com. They were actually very responsive about this issue.
jjdeluxe:
a ha - now I've got the connection.
OK. i've initiated the email to Obi Support. thanks for sharing.
obi-support2:
Indeed there is a bug in the OBi that may trigger FreeSwitch to send a 403 response (instead
the normal 401/407 to tell OBi to use new nonce for authentication).
If you need test f/w with this fix, please email support@obihai.com.
