Access Control

My IP Access List current reads as follows:

IP Address Type [Comment]

204.11.192.0/22 Allow [CallCentric]

1xx.xxx.xxx.0/23 Allow [u-verse]

192.168.2.0/24 Allow [LAN]

127.0.0.1/32 Allow [localhost]

69.90.209.57/32 Allow [VoipVoip]

99.xxx.xxx.xxx/32 Allow [Home Office]

In trying to block "everything else," I add the following entry: [iP address] 0.0.0.0 [Netmask] 0.0.0.0 [Type] Block

However, when I do so, my CallCentric trunk's registration drops and I receive continuous 408 errors.

What am I doing wrong? Thanks!

Can you remove your entry 0.0.0.0 [Netmask] 0.0.0.0 and check if Callcentric comes back? I heard they're having some issues lately.

 

I did as instructed and CallCentric came back. Being conscious of the troubles CallCentric has been experiencing recently, I tried this over a few days--and, each time, within seconds of deleting the [iP Address] 0.0.0.0 [Netmask] 0.0.0.0 entry, CallCentric would come back. Then, when I went back to the IP Access Control page & added [iP Address] 0.0.0.0 [Netmask] 0.0.0.0 and then checked under the Domain/Trunks tab, CallCentric (almost immediately) returned a persistent 408 Request Timeout.

 

Any thoughts?

Where did you get the IP for CallCentric? It seems that if I ping them it comes up with a different IP address on different days or times. After the last round of hits with CallCentric I had to switch one of my customers to Vitelity, they are cheaper and give you an IP to make a gateway with or a registration if you choose.

Something else, weird, happened yesterday. snom ONE blacklisted one of CallCentric's IP addresses, despite the fact that I specifically permitted access to the PBX to CallCentric's block of IP address (as shown above). The attachment to the e-mail from the system, notifying me of the blacklisted IP address, contained the following:

What am I missing here?
