Didn't know you could just do redirection on it's own. I lied unintentionally above, i don't use open ports and redirects together effectively doubling up.
I don't know anything about Voip but the default IP address's of a Draytek router begin 192.168.1.1 etc and if the omnipcx alcatel system is forcing a different IP address range then it won't work.
Outwardly i'll assume like any other device you don't need to open ports. Inwardly you do, so you'd open a port or range of ports in the router and point any incoming traffic to an internal IP address, the IP address of the omnipcx alcatel which should begin 192.168.1.?
I'll assume (again i know nothing about Voip) the omnipcx alcatel system will route the incoming connection to it's intended Voip phone.
I'm guessing, i know nothing about Voip phone systems. I think all you need to do is two things, make sure the omnipcx alcatel system has an ip address within the 192.168.1.? range I'd force it to start at 192.168.1.100 using bind to ip address and simply just open port 5060 (don't redirect, it's not necessary), just simply open it and point it to the ip address of your phone system. Ignore the need to do anything with ports 30000 to 65000 as i think the omnipcx alcatel system will be granted in/outgoing connections between this range automatically by the router, nothing to do.
Port 5060 at the IP address 217.145.67.2 is open. Port 60000 at the ip address 217.145.67.2 is Filtered
NAT > OPEN PORTS > Index No 1
Enable, give it a name, select the correct WAN interface, leave source ip as Any, type in the internal LAN ip address of the phone system. Start port 5060, End port 5060. Then Click OK. Done.
