Hello Brian I included that variable in vars.xml configuration file and after that change I get this. CASE 1: When I added the ext-rtp-ip value in verto.conf.xml, I got 2 ice candidates. However, they are the same (public ip). <param name="ext-rtp-ip" value="190.84.118.88"/> CASE 2: When I commented the ext-rtp-ip value in verto.conf.xml file, I only got local IP as ice candidate In these configurations ext-rtp-ip in internal and external sip_profiles are set with auto-nat values. How can I get both IPs (local and public) as valid Ice candidates in the SDP?

When I modify the ext-rtp-ip parameter, it only sends one option as typ host ice candidate. However, for my implementation I need to send both. What I need is the combination of those ice candidates, something like this: a=candidate:8228103366 1 udp 659136 190.84.118.88 31028 typ host generation 0 a=candidate:3496438569 1 udp 659136 192.168.1.170 24210 typ host generation 0 Is it possible to add both ice candidates in the same SDP from configuration files?
