I am completely stuck with VoIP under MT OS.
I was using a Suse linux based NAT/router to provide internet service.
My VoIP system (SIP + RDP) worked fine even with the NAT feature.
I then switched to Mikrotik
Now SIP is OK But I can initiate autio ( RDP protocol is not flowing thru the NAT).
Is there anything we can do about it or do I just have to give up MT OS?
try toggling (enabling or disabling) “h323” setting in “/ip firewall service-ports”
I did it. h323 was disabled I enabled it.
Problem remains the same. SIP signaling OK but RDP packets bloced
RTP doesn’t come TO or FROM you? or both sides?
do you have any firewall rules doing something with UDP?
RTP does not come from outside to the host behind NAT.
I have not really tested RTP from host to the outside
No specific udp rule set on the firewall.
RTP from host behind MT NAT to the oputside is OK
But No answer from the outside to host behind NAT
Any help ?
