I got a freeswitch that is behind nat and got three profiles.External (all calls are going through a proxy):<param name="rtp-ip" value="$${local_ip_v4}"/><param name="sip-ip" value="$${local_ip_v4}"/><param name="ext-rtp-ip" value="$${external_rtp_ip}"/><param name="ext-sip-ip" value="$${external_sip_ip}"/><param name="local-network-acl" value="localnet.auto"/>Internal (phones on the same lan as FS)<param name="rtp-ip" value="$${local_ip_v4}"/><param name="sip-ip" value="$${local_ip_v4}"/><param name="local-network-acl" value="localnet.auto"/>Wan (phones that are not in the same LAN, connecting from internet)<param name="rtp-ip" value="$${local_ip_v4}"/><param name="sip-ip" value="$${local_ip_v4}"/><param name="ext-rtp-ip" value="$${external_rtp_ip}"/><param name="ext-sip-ip" value="$${external_sip_ip}"/><param name="local-network-acl" value="localnet.auto"/>The problem is that phones registered on the internal profile gets RECOVERY_ON_TIMER_EXPIRE error after 40-60 seconds. Audio works fine in all profiles.Log from a call:I'm running freeswitch with the -nonat option.
