Hello all,

I have been round and round with the Inter Tel System, and my ISP. We opened a new office on the other side of town. My boss has had me place our IP phones there, they are all 8660 or similar. I am running version 8.2 of the software.

The problem I am having is this:

From the new remote office(NOT THE location of axxess box)
I can:

a. ping the external IP of my Axxess system (assigned directly to the IP port)
b. open the DB manager and access the database
c. create a telnet session to the system

However,

I cannot get ANY phone to connect to the remote IPC card on port 5567 from the remote location. All I get is IP card not found, except in one phone I believe it said IP card not programmed.

These conditions apply whether or not my Pix 506 and 3600 router are in the loop or not, all IP's have been added to the appropriate access list.

Phones physically plugged in at the PBX location and pointed to the LAN address of the system ( I changed the address and rebooted it to see) work fine.

I have changed the address of the phone system to a public one( changed the one in the IP port associated with the card), with nothing at all in between it and the internet, but still no phones connect.

The questions I pose are these.

1. Do the phones each require a static NAT entry for an external IP to work ?

2. I am using 2 8MB cable modem lines for the connection and they swear no UDP ports are blocked, so I dont see why it wouldnt connect, is there another place to change the IP address besides the system manager and the IP port associated with the card ? What am i missing ?

3. Can anyone tell me why I would be able to access every feature of the system remotely except being able to connect the phone on 5567 unless its blocked?

The reason my PBX is in a different location is that we built a building outside of town before seeing if we could get a T1 circuit out there.

(I had nothing to do with this, it was started before I came to work here or it wouldn't have happened)

To make a long story short, my tail's going to be in the wringer if I don't get this figured out fast........Anyone who can help, thank you in advance.

I should also mention that I have programmed the handsets using the 7 and 8 held down during reboot feature to the proper addresses

Ok, never mind got er done.

Charles,

I had similar problems connecting my IP phones.

What solved your problem? I had similar problems and ended up using vpn hardware to address the nat issues. For $110.00 i saved hours of headaches. It worked like a charm and also allowed me to get rid of the cisco soft client for remote pc users. (two birds with one stone)

I do have a couple sites that only need ip phone and any help would be appreciated!

Please let me know the solution if you have time.

The issue is that there are two IP ports on the Axxess system that do seperate things. First, the LAN Port on the CPU is for database management. This needs to have an external IP address assigned or routed to it if you want to do remote database session programming.

Second, the IPRC card has its own, seperate IP port. You need this one to be in your IP network, and addressable from the outside world as well if you want to have remote IP phones. The IP phones need to be programmed to look at the external IP of the IPRC card and it will all work.

Good luck!

We had what sounds like a similar problem...

We tried everything we could think of...changing the router, updating the firmware, even a phone got changed out.

Eventually, the place lost all internet access..even though all the lights were on on their cable modems.

A tech from their cable ISP came out and replaced both routers...as he did that, he checked all the connectors at the drop. He ended up replacing every connector. I heard him say more than once "I'd like to slap whoever did this".

:rolleyes:

After that, the phones worked perfectly!
