[Freeswitch-users] How to reject SIP messages based on user agent?

[Lợi Đặng]

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.
