[asterisk-users] Incoming Call trouble with new *Now 1.5 setup

[Zaheer Master]

Hi All,

I'm having a bit of trouble with my new *NOW setup.

I've downloaded and installed *NOW 1.5. We're using 1 SIP Trunk from
SimpleSignal.com. Outbound calling works great, but I'm having some trouble
with inbound calls.

 

First, we would get the "the number you have dialed is not in service" error
on inbound calls. After some googling, I found out that I needed to enable
anonymous SIP calls in to the system. When I did that, it started to work. I
was a little worried about potential security risks so I wanted to filter
inbound calls by DID. I tried the formats DID, +DID, and +1DID, but all of
them caused the box to hang up or give me the "number not in service" error
message.

 

Are there any known security risks by allowing anonymous SIP and having an
ANY/ANY inbound route?

 

Thanks in advance for any help!
