For a little more sanity modify the 9100em SIP service definition from only ONE UDP port, 5060, to include expected defaults- or YOUR SIP and RTP ports.. you’ll be redefining the 9100 SIP service to be voip service as creating your own voip service definition will not suffice — thanks verizon for making “open” RG “better”.
Yes, delightfully you will be making duplicate modifications in several locations in the config file: service, meh why ruin your fun you can find the rest right? protocol(17) = UDP protocol(6) = TCP. For a little more joy craft some advanced filters (firewall settings, yes, advanced filtering) to allow traffic in, Initial Rules, from your ITSP server(s) or otherwise with the SIP/RTP ports you use. Enable rules logging to verify, syslog daemon preferred, but do not leave enabled.
