Hi,

Can someone let me know how/if its possible to block based on UserAgent and if you can use for example regular expression to specify a range of extns numbers that register within a SIP domain?

Thanks

You can add useragent to the file /etc/blox/sipua.cfg to block (apply changes required)
For extns, you need to configure SIP header manipuation

Sorry is there a way to set the SIPUA.cfg so its an allow list rather than block. So I can allow one UA and block the rest ?

after updating sipua.cfg (allow list)

In file /etc/blox/blox.cfg.m4

if ($ua && pcre_match_group("$ua", "0"))

change this to

if ($ua && !pcre_match_group("$ua", "0"))

NOTE: apply changes required
