I setup Simonics SIP yesterday, now getting hammered with call from 123-456-7890
Jeff-66:
was working fine yesterday after I set up my Obi100 with Simonics SIP. even now I can make calls, and receive calls. I'm getting Caller ID info on incoming calls. Normal calls I make & receive are showing up correctly on the G-Voice site.
However, every 1 to 3 minutes, I'm getting a call from '123-456-7890', with no name. If i pick up and answer, there's nothing on the other end. I can't detect anything. If I don't answer, sometimes it goes to voicemail (no msg left though) and sometimes it just hangs up before voicemail.
Normally, this would be easy to handle by going to g-voice and blocking the number, but the strange thing is these calls do not register on g-voice at all as an incoming call. G-voice does not let you block a number unless it's a registered call.
Anyone else experiencing this or know what might be wrong?

Some routers do not do NAT properly. When you connect your device to our SIP gateway they then open SIP from the whole world back to you Obi.
You can get a better router or change your Obi's SIP listening port so that there is not an obvious path for the SIP scanners to get to your network.
Search forums for "ghost calls" or "SIP scanners"

Hi Bill, thanks for the reply, and thanks for the service. It's much appreciated.
I will research those, and try to change the listening port. thanks again!

You're getting hit by SIP scanners. Either of the following solutions should fix the problem:
1>Using OBi Expert, change Voice Services-->SPy Service-->X_InboundCallRoute to the following:
{>GV1XXXXXXXXXX:ph} (This is using your "SIP Login/prefix" as seen on your Simonics web page)
y=SP service number (SP1, SP2, SP3, or SP4 under Voice Services) being used for Simonics
XXXXXXXXXX=Google Voice number
2>Using OBi Expert, change Voice Services-->SPy Service-->X_UserAgentPort to a random number between 10000 and 65535, for example, 55120.
y=SP service number (SP1, SP2, SP3, or SP4 under Voice Services) being used for Simonics
Important: You must uncheck both boxes to the right of the field you are trying to edit. Make the change in the exact order shown below. You can't do Step 2 until you do Step 1 first.
Step 1: Uncheck box under OBiTALK Settings for the field you wish to edit
Step 2: Uncheck box under Device Default for the field you wish to edit
Step 3: Edit the field you wish to change
Step 4: Submit and save your settings

You're getting hit by SIP scanners. Either of the following solutions should fix the problem:
Using OBi Expert, change Voice Services-->SPx Service-->X_InboundCallRoute to the following:
{>GV1XXXXXXXXXX:ph} (This is using your "SIP Login/prefix" as seen on Simonics web page)
x=SP slot number being used for Simonics
XXXXXXXXXX=Google Voice number
Using OBi Expert, change Voice Services-->SPx Service-->X_UserAgentPort to a random number between 10000 and 65535, for example, 55120.

This was a homerun! I used your 2nd method and it worked. The scans stopped 100%. They were coming in every 10-15 seconds, tying up the phone. it was highly annoying. Thanks a ton for the info!
