I think i had trouble the first time I set up IP phones on the XTS or maybe it was becasue I was using RSGMs, they were a pain.

I found it, Larry. Thanks for the suggestion. I just think that site is so overly-complicated that I purposely avoid it at all costs.

Derrick, I swear that I set up my first IP phone on our XTS with not one single issue. I doubt that I spent five minutes on it. As for the RSGMs, I feel your pain.

The biggest issue with IP phones on the XTS (forget the RSGMS) is where the voip cards are located....I have learned to always keep them in the last slot, not the Voice Mail. It is a pain to create ip extensions only to have your voice mail ports change numbers on you.

So what is the suggested way to setup an actual "remote" IP Phone from say a home user? Should you setup a hardware VPN then setup the phone? Or can you just point the phone to a public IP Address which is directed toward the SBX? Also are there two LAN ports, i.e. Lan and WAN?

There's no need for a VPN; a static IP address for the card is all that is required. The optional IP card is used for IP phones and networking. The on-board LAN port is used for e-mail notification and programming.

I am trying to get a remote phone working, I have gone through and port forwarded all ports that are on the vconnect page, if I plug the phone into the internal network it works fine. If I go somewhere else and plug into their network I get no response from mfim[r]? Any suggestions? We want to set this up for our salesmen so they can have phones at home, but if they want to bring them into the office and work it will just work?

You need to put the sbx in front of any router or firewall and give it
its own public ip address. Make sure the phones are set for DHCP.

Unless you're just doing it for a short term test, it is not good practice to put a phone system in front of the router/firewall. If you do, you will be opening every port on the system to the entire world. Plus, you will not be able to provide any QOS to the phone system.

I assume you changed the IP address of the phone to your WAN address?

You forwarded the ports to the VOIB IP address?

In PGM 340/341 you verified your gateway address and that the Firewall IP Address is set to your WAN IP?

For a test, try opening up ports 5060-20000 to the VOIB card, then see if it works.

5060 and 5061 are sip ports the IP phones use h323.
Also the phone system LAN card is behind the firewall, as well as the VOIB. I just cant see why you have to put the VOIB on a public IP because of mixed environments where you may have IP phones inside the network and remote users. You wouldn't want phones on your internal network going out over the public internet and looping back to your network.

How is the phone suppose to get to the VoIP card from the outside? Are you using a VPN?

I know 5060-5061 are SIP ports. The ports I gave you are the ones we open up for IPECS, which uses the same phones. I've never tried just opening up the ports that was suggested in the V-Connect document.
