Interconnecting Panasonic TDE-200 PBX with CCME 2901 through h.323 trunk

One day, i've received a task to create an interconnection between two different PBX's.

At, first is was difficult, cause, i didn's find any material and articles about such interconnection. But...a last...after few hour's of test's and debugging, i've solved this task.

Here is my advices:

On Panasonic we've phone nubmerx 2XX, on CCME - 5XX

First: 

Panasonic site (Configuration through PBX UMC)

1) Insert a  V-IPGW16 card in your virtual unit (Item - 1.1)

2) Then go to properties of the system unit (righ click on V-IPGW16)

3) Click on gateway settings

4) Fill all fields in first line (specially - IP address in my config it's - 172.16.0.1 (and remember the number of gateway)). According to my example my gate number - "1"

5) Then click on D2IP and write in first column first nubmer of CISCO CME phone numbers, in my config it's - 5, second column next possible amount of numbers befor "5", my config - "2". And the last column - gate number - according to   item 4) - gate number - "1"

7)Then item 2.6.1 on PBX UMC, choose third tab (numbers of local PBX). And for example in first line, write the first nubmer of phones, that belong to CME, according to my example, it's - 5.

That's all on Panasonic site

Second: 

CCME 2901 (A bit easier...)
