Obi110 ghost calls / European line settings?
Arpad:
I just hooked up an Obi110 and am using CallCentric as the SP1 provider. Within hours, I started getting "ghost" rings. It rings for a random amount of time and there's nobody there.
The logs on the Obi110 show this every three to five minutes:
Terminal ID LINE1 PHONE1
Peer Name
Peer Number
Direction Inbound Inbound
09:41:13 Ringing
09:41:24 End Call
I tried to follow this guide and implemented #2 and #4: http://www.obitalk.com/forum/index.php?topic=5467.msg35387#msg35387
Actually #4 was already set in the config and #2 seems to fix the problem when I set the X_UserAgentPort to 5081 (as suggested by Call Centric support). HOWEVER, the settings reverts back to 5080, which doesn't seem to help. (Also, I can't seem to change the admin password - it doesn't "stick" either). Also, it seems like more of a stop-gap measure until 5081 becomes a target.
Which brings me to my absolute confusion about how all this works. I don't have port 5060 open, inbound on my network, or any other port for that matter. Normally, it seems to me, I would have had to port forward to the device and then I could see problem occurring from SIP scanners. I guess the device registers with the ObiTalk network and connections are proxied into my device from an outbound connection? But then I really don't understand what I can do to prevent scanning.
I could do some tcpdumping and figure this out but that seems like a lot of work and no guarantee of success since I haven't the foggiest about how I could affect this.
I can't effectively use the device with it ringing every 3 minutes. Help?

See http://www.obitalk.com/forum/index.php?topic=92.0 for the probable reason that your configuration changes are not "sticking".
Arpad:
Cool. Yup. I was just starting to figure that out. Your link helps even more. Thank you.
5081 as the UserAgentPort seems to have eliminated the unwanted calls. I haven't tried to see if I can get wanted calls, yet.
If someone could point me to a good explanation of the network configuration that makes all of this tick, I would appreciate it.
Arpad:
Port 5081 stuck but didn't fix the issue. Still getting inbound connections. There were a few hours without issue but now they're back every 5 - 15 minutes.
So I still don't understand. This Obi device is awesome but if I can't stop periodic ringing then, aargh....!

What do you have in X_InboundCallRoute for SP1 ?
