Hi all,

I was higly recomended to your forum, and after reading some of the threads I can understand why.

I have a IP phone problem. I have installed an OS12 system in UK. it has one IP phone at main office and three remote ip phones. the Office ip phone works fine however the remote phones can hear office but office cannot hear remote side.

I have opened ports 9000,6000,and 30000-30016 on the routers and forwared the ports to MGI card.

I am running out of ideas. can any one help?

OS12 is runnung V2.66
IP phones are V3.17 and V3.22

Is your system setup as Private with Public and are the phones setup as Public with Firewall?

I've found this is the simplest reason for the problem (and the one I forget the most).

Jon. This is a hot topic here in the Samsung threads. VIBob is on the money but I would like to add this, If there is a problem after making sure that you are private with public and Private with firewall. You may have an unforseen network issue.

Either way do a search on "private" and you will see the many helpful threads here.

By the way welocme to the Forum.

Jon I think you'll need to forward port 9001 as well as all three other ports that are used for IP phones. IP address of the system needs to be public as well as the IP phones in IP type public/firewall need to be set. Hope this helps.

I had this problem just this weekend setting up an OfficeServ 7200 with MGI16. I had all the ports forwarded, I even tried putting things in the routers' DMZ's.

What I kept getting was that the remote ITP5121's could receive audio, but couldn't send audio.

What I figured out was that I had not set the "public IP" address for the MGI card. Once I set the MGI's "public IP" to the Internet IP of the router, it started working.

But THEN the in-house ITP's could no longer get a dial tone when pressing 9.

So what I found was that I had to set both the in-house and remote ITP's to use the Internet address of the router.

Hi All,

Thanks for the help, sorry it has taken me a while to reply. We did solve the problem by setting the MGI as Pulbic with Firewall and it worked fine. There were errors on the router as well but that is all ok too. We are hving an issue with the phones dropping out all the time but we think this is a DSL issue or a network issue.

Thanks for the help we did set as Public with firewall and it worked. Sorry for the delay in replying.
