Blocking inbound SIP spam calls

<< < (2/3) > >>

ianobi:
You could have a look at the bottom of this page:

http://www.anveodirect.com/about/faq

I think you just need the SIP ip addresses. The problem with anveo and other service providers is that they often use a range of ip addresses. The OBi can do a list, but not a range.

Have a search around on this forum for "accesslist" there are pros and cons for using it.

Diana:
Anveo has three IP address:

Quote

sip.anveo.com:5010 (USA)              [72.9.149.69]
sip.ca.anveo.com:5010 (CANADA)    [67.212.84.21]
sip.de.anveo.com:5010 (GERMANY)  [176.9.39.206] (not 100% sure of this one)

Interesting... I wonder if http://www.anveodirect.com/about/faq only applies to Anveo Direct, or if that FAQ is out of date.

I will have to contact Localphone on that because they work with different providers for their DID's and there are often problems with changing things.
But it seems to me that the IP address  list is the best solution because anything else could cause problems with international calls where you often get weird or no caller ID's depending on the providers on both sides.

I had success with item # 2 posted in "Reply #1 on: March 09, 2013, 09:39:44am  by  ianobi."
My setup is obi100 with Google Voice on SP1 and Anveo on SP2 for e911 service only.
I read elsewhere that Google Voice is not as susceptable to SIP spam calls so I concentrated on SP2 Anveo service.
I made the change on April 11, 2013 and here is the note I made for myself to document Expert mode configuration changes I made.
