Description:ICE resolution in res_rtp_asterisk currently obtains host candidates from all available interfaces on the machine, causing STUN to be attempted on all of these and increasing the size of the candidate list. In many cases, there are interfaces / subnets that are not of interest for ICE/RTP, for example local interface or VPNs. This enhancement provides the capability to blacklist subnets in rtp.conf using lines like:
{{ice_blacklist=10.5.5.0/24}}
