Using IP Trunks or Extns via both Lan ports 1

[Firebird Scrambler]

Has anybody been able to get a BCM system to have it's IP Trunks work on e.g. LAN 1 & IP extns working off e.g. LAN 2?. I'm also wondering if it's possible to get the IP Phones or Trunks to register off either Lan port?.
Would I need to setup the default Gateways between the 2 LAN's?. Is there a guide that I could follow please, assuming that this can be done.
I've recently managed to set-up my BCM to a Succession 1000M via the Gateway & I'd like to make use of my other Lan port to expand my network.

If anybody is interested, I've jotted down a few notes that I found to be useful.

BCM to Gatekeeper basic configuration guide


1) Create a H323 alias in Gatekeeper & then program IP address and alias
under "BCM Services IP Telephony H323 trunks".

2) In alias field enter e.g. NAME:H323BCMID (where
H323BCMID is H323 alias you've created in Gatekeeper)!. Make sure that you use "NAME:" before the alias name!.

3) Change "TTL" field to 30 seconds. Then click on "Services".

4) Highlight H323 Gateway service & in upper dropdowm menu, disable the service. Then enable it again.
It should register on the Gatekeeper within 60 seconds.

Useful info to remember with BCM configuration programming


1) RAS Port = 1719 (I changed mine to "0" as H323 Trunks failed!).

2) Call Signalling Port = 1720.

3) Select the "Gatekeeper Resolved" or "Gatekeeper Routed" option.

4) Select the "Fall back to circuit" option as disabled.

5) Tick the box against "Forward redirected OLI".

6) Tick the box against "Send name display".

7) Untick the "Remote MNS" box.

8) Tick the "Enable H245 tunnelling" box.

9) Against Gatekeeper protocal, select "CSE".

10) Check that "echo cancellation" is enabled.

11) Against "T38 UDP redunency", use "2".

12) Under "Services" Select "Net Link Manager" & then go to
the "Permanent WAN Connection Setting". Enter the Gateway IP
address in the "Next Hop on Primary Link" field.


BCM Port Information

Port 6800 is used to enable you to access unified manager via Internet explorer.

Also Ports 1718 UDP H.323, 1719 UDP H.323 and 1720 TCP H.323 - Call Signalling.

Direction >> Channel Source Ports Destination Ports COS

i20xx to BCM Signalling 5000 7000 0xA0

i20xx to BCM Media 51000-51200 28000-28511 0xB8

i20xx to i20xx Signalling 5000 7000 0xa0
(between BCM G/W)

i20xx to i20xx Media 51000-51200 51000-51200 0xB8

Note!
The H323 & SIP IP Trunks can cause confusion if the MAX setting = 60
H323 defaults are usually 001 to 030 & SIP defaults are 031 to 060.

I'm sure that there are some other settings that should be set, but this seems to be OK for me.

If it's working, then leave it alone!.

Far as I'm aware, you can only run IP off the NIC that is configured as the "published" IP address under the VOIP configuration.

Thanks for the message. I was hoping that I could also have IP phones off e.g. Lan1 to be working on Lan2 by using NAT set to allow the IP port 7000.
I've tried to have my 2 IP Trunks working off Lan2 with the phones on Lan1, but you are correct as you have suggested above.

You can only use IP phones on the NIC with the published IP. I am not sure why they would do it that way. It would be nice to be able to have IP phones on both NICS in some cases.

It's a shame that there is no way that you can connect anything IP using the unpublished Lan port.
I've added some more info on connecting a BCM to a Gatekeeper system below..

H323 defaults are usually 001 to 030 & SIP defaults are 031 to 060.

To get the Name display working, make sure that you have keycodes for the
"MCDN" package & the sites Business Name is entered under "General Settings"
You can only enter up to 8 characters.

Succession Gatekeeper to BCM configuration basic configuration guide

1) Create a H323 alias in Gatekeeper. Select the "set Standy DB view" first!.
Go to "Configuration" then select "Gateway Endpoints". Configure up your
"Show Gateway Endpoints for (Service Domain / L1 Domain / L0 Domain):".

2) Click on the "Add" button. Against the "Endpoint name" put in your alias name
e.g. "H323BCMID" (Don't use NAME:!).

3) "Endpoint authentication enabled" can be either set to "Authentication off" or
"Not configured".

4) Select "Static endpoint address type" as "IP version 4" & "H.323 Support" as
"RAS H.323 endpoint". I had the "Network Connection Server enabled" ticked.

5) Save the setting. Go to "Configuration" then select "Routing Entries".
Use "lookup" or enter under "Gateway Endpoint" your H323 alias name
e.g. "H323BCMID" & select the "Add" button to enter in a DN entry for that site.
I use the "DN type" box to select "Private level 0 regional(CDP steering code)".
The "DN prefix" is the DN range that you are going to use.
i.e. digit "2" for DN's 2xxx.
I normally enter in "1" on the "Route cost (1 -255)" box. Click on "Save".

6) Go to "Tools" and then select "Database Actions". Select "Roll over and Commit"
to activate the changes made. Wait a minute before attempting to make calls.
