HOWTO: Thwarting SIP Scanners during Set-up
Mango:
In that case I suggest you make a new thread. You may get more exposure that way, since this problem is not related to SIP scanners.
I suggest you state what appears on your Caller ID and what happens if you answer the phone.

Hi All,
I am a newbie to this SIP scanner issue. I setup Obihai 202 with 1 phone line using freephoneline.ca. This setup worked perfectly fine for almost 6 months. 2 weeks ago I changed my router from motorola to a "Hitron" due to a upgraded internet service. Since then I have started receiving calls from 1001 and 3001.
So I went into the forum and started researching and came across this thread.
1. Based on the information I have Unchecked SP2, SP3 & SP4. Does this need to be done for ObiTalk too?
2. My X_UserAgentPort is 5080
3. My X_InboundCallRoute shows as {ph1}. Here I see suggestions to modify this to something "XXXX"|aa,some phone number...I am getting thoroughly confused here. Can someone guide me?
Best Regards
PP

1) OBiTALK can stay active.
2) Change your X_UserAgentPort to a random number between 20000 and 65535, such as 31688.
3) Follow step 3 from the first post in this thread: http://forum.fongo.com/viewtopic.php?f=15&t=16090
as an alternate to 3) you can use X_AcceptSipFromRegistrarOnly if you have a newer firmware version.
When you are done, test to be sure legitimate incoming calls still arrive. This should block the scanning calls.

Hi Mango,
Effected the changes, and phone is still working. Now to wait and see if the scanning still happens. Thank you so much for your help.
+1 to you.
