weird RTP problem

[ogTOKYO]

So I'm connecting a remote phone using NAT.

Port forwarding is working great, we use one X mobile occasionally and voice is 100%.

However, we're trying to connect and what i'm getting is out of range destination RTP ports. Example:

LocalIP:46401 <-> public:23051
LocalIP:46401 <-> public:23052

no audio, but phone logs into the extension just fine. Anyone have any idea? Remote is enabled, both 323 and sip.

and yes, this is a no audio problem

Hold plays hold music, but since the RTP ports aren't matching and there's no audio statistics in SSA a during a live call, I can only assume it's because it's not getting through the right "door". Don't know why it's failing to reach the right ports.

Check RTP Sessions in Monitor and you'll see which ports it expects to use.

Seems a bit off that it would use 46401 if it's not entered in the LAN tab.

remote phone is using port 46xxx out of my network, but destination is random and never hits the 49xxx-53xxx ports on the avaya network end. I have the RTP natting set, otherwise OneX pro wouldn't work. Atleast that's what i'm assuming is the case. lol.

Well, if you wanna get somewhere you should provide a monitor trace or pcap so we have something to go on.

Also the RTP range should be changed for security reasons, new defaults are 46750-50750 for IP500 and 40750-50750 for SE.
