Hi,
Please tell me how to block VoIP with Content Filtering not using L7 Protocols.
tell us how you can detect this traffic sip. I mean, layer7 can work with sip pattern but with layer3 (osi) only you can work with IP, so, you know the sipserver?. You must to know to detect this service.
I guess you can use a mix with tarpit and sip connection type suppose.

Hi,
Dear right now i am using L7 to block this and it is working great. Just wanted to know how to block VoIP using content filtering. I dont know SIP or any other server’s IP.
How to locate a VOIP address? I know the local host but not the VOIP company actually directing the traffic. ? I have an IP address for a VOIP provider. A whois shows that this is a local telco but I need to know who the actual VOIP company is, this company is using the local telco as a host to direct traffic. Thanks!

Hi mudasir, could you please explain how you manage to block skype and actionvoip using L7 ??
I did this:
/ip firewall layer7-protocol
voip ^.+(yahoo.com|skype.com|teamviewer.com|actionvoip.com).*$
/ip firewall filter
For BlockedVoIP
chain=forward action=drop src-address-list=BlockedVoIP layer7-protocol=VoIP
But it is not working, can you help me?
Thanks in advance,
Hector.
