[OpenSBC] SIP URI Blocking

[OpenSBC F. <ope...@op...>]

Hi all,


I have setup a  OpenSBC enviroment.  We want to block SIP URi's here  No IP.
I'm sure it is possible to do that so in OpenSBC, we rather use the webgui instead of creating XML files. 
I would appreciate if one could tell where to search in the gui, or if its in XML, where to do it.

TiA,

Regards,
Imran
