18.06 SIP problems

Hello all. I have static public IP on WAN.
On 17.01.05 and earli it was necessary to install kmod-nf-nathelper-extra and reboot router, to make SIP-phone behind OpenWRT goes work.
On 18.06 it doesnt work. I have problems with RTP traffic.
In INVETE request, Contract value looks like:
Contact: sip:000@
but should Contact: sip:000@PUBLIC_IP:5060

How to fix it? Thanx alot.

ps: FW was openwrt-18.06.0-ar71xx-generic-tl-wr1043nd-v3-squashfs-sysupgrade.bin

You need iptables-mod-conntrack-extra as well.

iptables-mod-conntrack-extra isnt help me :frowning:

Did you also install kmod-ipt-raw ?
