SIP scanners
shap:
I think you are not correct. OBi device can not open any port (unless you are using PnP). What it does is connecting to the SIP server and maintaining an "open" connection to it. But even in this case you can miss some of your calls.
In general, you should open 5060 port (or any other you assigned) from your SIP provider to Obi device.
To block scanners or any hacking on this port, you should create a rule in router that accept traffic to port 5060 only from the IP of your SIP provider. This way you will eliminate night "calls" or possibility to hack your device.

What does that rule looked like for gv?

I assume that "you are not correct" is addressed to me ;)

Isn't it the same thing?

Only if firewall for some reason closes the port before device is re-registering... or something... I've never seen it happened.

Never had a need for it! I opened a few times for troubleshooting; confirmed that opening the port makes no difference, and closed it back. You are not opening ports for Skype, or for any of your IM clients - no need here, either.

I would be a little nervous... Google is not going to inform you if they change IP; moreover, I think there are several IPs that they use. Finally, my router is part of my AT&T U-Verse modem, and what you are describing is just impossible.
As this long thread indicates, there are several ways to accomplish that; with different levels of success. In my case scanning was on port 5060 only; so I switched SP1 to 5064, and scanning stopped.

Hi,
Rank newbie here. So am I to presume that xxxxxxxxxx@sip.voice.google.com where Xs represent you GV number, will not work for a Google IP addr?

Phillip,
Do you mind starting a new thread? When you do, please explain what you are trying to do. As stated, your question is very difficult to answer...
