Unknown peer inbound on SP1 in middle of night w/o a trace - help!
ChrisF:
My setup is an Obi110 connected to the web and Voip.ms setup as SP1, with a regular handset connected to the Obi.
Twice in the past two weeks, I've received an unknown peer name/number call at around 4:30am (both times). The phone would ring, I'd answer, hear a blip like a long distance call getting connected in the 1990s, but no one / thing on the other end. If I'd hang up right away, the phone would immediately ring again. Only by keeping the call engaged for 30s+ and then hanging up would it end.
Obi shows the following log:

Strangely, Voip.ms call logs do not show any calls occurring at that time.
Has anyone experience something like this? I thought of doing a time restriction on Voip.ms, but that does no good if it's an Obi110 glitch. I'd appreciate any help.

ChrisF,
Welcome
Others have reported similar events. More than likely something scanning the internet for open voip ports. Find the ip address of the voipms server, then put that ip in this section. It should end:
ITSP Profile A/B->SIP->X_AccessList
ChrisF:
Thanks for the reply. I did manage to find another topic on the matter as well. I didn't know the cause so I didn't realize my issue had overlap with others.
I'll try your voip.ms IP suggestion and the inbound call route blocking I've seen and hopefully no more awful wakeup calls.

What might the IP be for Google Voice for ITSP Profile A/B->SIP->X_AccessList?

Hortoristic,
Google voice ip range:
74.125.0.0 - 74.125.255.255
http://www.whois.net/ip-address-lookup/74.125.131.125
From my location in Montreal I specifically obtain this ip (as per my router firewall): 74.125.131.125
Also ping this address in the DOS prompt and see what it returns to you: voice.Google.com
