Dear forum members,
I’m operating my Tenor A800 behind a NAT. The problem that I’m facing is that whenever I’m making an outgoing IP call, I can’t hear the called party’s voice but instead they hear me very well.
What I concluded from this, is that the voice packets are passing away from my NAT/Router correctly but the return path is not clear and the packets get lost. I believe this is a problem of my NAT/Firewall not correctly translating the ports.
Could anyone advise how to get out of this trouble, or at least what ports can I manually configure on my router to overcome this issue.
Any help is appreciated!

Your problem is indeed NAT. If you have to oepn each and every ports, u’ll end up selling tylenol!!!
Check if your modem/router has DMZ mode. If so, place the Tenor in DMZ mode, i.e set the Tenor ip address in DMZ. Thats all and no more configs.
Hope it helps you.

I do not agree with the statement about selling Tylenol.
He will be taking it all!!!!! Not selling it.
There is a list of the ports that you need to configure on your router to pass trought on the Quintum site.
The site is not the most organized site that you will find, but have a ton of usefful information, buried three or four levels deep.
Try the following link:
A couple of hours reading this documentation could be a well spent time.
Best regards, and the good news is that once you get it work, is it a workhorse.

Thanks for your good advice. One thing I’m not sure: Why Quintum announces that the Tenor boxes work under NAT-ed LAN with its “NATAccess” technology. If I have to open the ports on my router or have to put the gateway in the DMZ, than what’s the use of NATAccess in this scope?

After you put the Quintum in the DMZ, you still need to do a port forwarding from your router. On Quintum website you should able to find a document name Tenor and NAT listed the neccessary ports needed to be open in the router. Good luck8th April 2004 at 14:54 #26777JamesGuest
Thanks for the valuable information, Noname!
I’ll try to utilize it!

Are you sure about the port forwarding after tenor is in DMZ??
I don’t think so because I got it up without any port forwarding any of the ports.11th April 2004 at 01:53 #26779romulusGuest
james, you can registered with our softswitch with an assigned H323ID from us and all your problems will go away. we have customers who uses a800 on a private net (10.x.x.x) and a public IP (DHCP’d)from his local ISP. Otherwise you need to re-direct the ports from your router to the a800 and make sure change the ext. IP under “config unit 1” to match the external IP from your ISP. If your ISP changes your public IP, you need to change your ext. IP to match it. very painful..13th April 2004 at 20:45 #26780JamesGuest
