oh many thanks, David, the commands are already in FreeSwitch page. Actually, expecting a B2BUA like FreeSwitch process SIP messages as a SIP proxy is not really a good approach. So using iptables will help me achieve my goal somehow, if there's no workaround. rgds, Loi Dang Thanh Phone : +84. 1224.735.448 Email : loi.dangthanh@gmail.com On Sun, Feb 26, 2017 at 9:26 AM, David Villasmil < david.villasmil.work@gmail.com> wrote:
That is correct, it will. But you could also use iptables for block them. Let me know if you need the command, i have it somewhere :)

hi David, I'm afraid your solution can only be used to process the INVITE message, which create a channel.

You could use the variable sip_user_agent and reject them.

hi,
you can do it using iptables:
iptables -I INPUT -j DROP -p udp --dport 5060 -m string --string "zoiper" --algo bm

Hi list, I have a list of user agent regex pattern. For example: ^Asterisk PBX ^Zoiper ^SipP$ The list will have more and more members by time. All I want is to reject all the SIP messages (not only INVITE) that has User-Agent header value match any of the pattern in the list. How can I do that?
I know this can be achieved with a sip proxy placed before FreeSwitch, but I don't want an additional SIP component for just that.
Any help would be appreciated. rgds, Loi Dang Thanh Phone : +84. 1224.735.448 Email : loi.dangthanh@gmail.com
