SIP scanners
Hortoristic:
Using this setting below; in my X_InboundCallRoute - I have not had one single SIP scanner get through in a few months. I'm even still using the default 5060 + ports. I receive calls from UK, Canada and USA just fine.

I wish I could say the same. I had to modify mine:
{asterisk:},{'asterisk':},{('asterisk'):},{(?|@|@@|@@@|@@@@|@@@@@|ipphone|un@@.|anon@@.):},{ph}
The only true solution is if OBi implements one of the features mentioned here:

I have obihai logs forwarded to my linux server, and I found something interesting there. Here is what I get:
Code:

SIP DLG reject: 486
In other words, it's not just a scanner, but it looks like an attempt to make an outgoing call to Palestinian territories in Israel (972-59 number). I don't know what these SLIC commands mean. CID to deliver is the CID I saw on the phone screen. An entry in call history also says From '201' SP1(201).
Obviously, there is no record of such call on my VSP call history - so it is clearly a call directly to my IP address port 5060
johnpane:
If I have my OBi behind a firewall and have not opened any ports for it (5060 or otherwise), will this avoid problems with these SIP scanners?
Thanks,
John
Felix:
The short answer is "No". Opening ports through firewall has no relevance on the issue.
When OBi registers with the provider it establishes a connection and thereby opens a port. Note, it is not unique to OBi - your Skype or any IM program does the same. Otherwise you wouldn't be able to receive calls / IM messages.
Hope that clarifies.
