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.
