Hello community,
i have a RB1100AH with contrack enabled. If try outbound calls, i got the connection established but no voice. Inbound calls working fine.
There is no NAT on RB1100AH that could affect the VoIP since i have an offical ip but if i disable contrack, voice on outbound calls is transmitted fine immediatly.
The problem is, that there are some people without official IP, so contrac has to be enabled for NAT.
I also tried, if it is a problem with the nat rule, but disable the nat rule has no effect, neither add an accept rule to sort official IPs out of nat chain.
/ip firewall service-port sip enabled or disabled changed nothing.
