two IPO connected via tunnel - how?

[tmckeown]

Hi,
I have an IP 412 system that is in our main location. We have another office that has an IP406 system. Both are running build (65). I also have a tunnel between the sites. I would like to configure the IPO system to talk with each other, as if it were one large network. Is it possible?

I already know how to and have configured many 5610 IP phones to connect via tunnels from the homes of many managers. Is it something similar.

If someone could point me in the right direction to start, I can do the research and configure it. I'm just not sure where to find any info on it. I'm sure many of you have done it already. Can you share your knowledge with me?

Thanks,
Tom

so you have a vpn tunnel
first of all
you have to be sure that there are NO duplicate numers and names in the two systems
if that is not the case do the next step
make an ipline in lines (both systems)
also these have to be unique in both systems
i asume there is an iproute to the vpn router otherwise the ipphones at home don't work
when you have made the 2 ip lines (one in each system)you check "voice network" and "direct media path"
don't forget the gateway ip adres (vpn router)
this should give you a big start

 

[tmckeown]

Thanks for the response. I hope I can ask for a little more clarification.

When you state to make an IP line, do you mean to go the line selection and create a new VOIP line? I think that's what you're saying. I see when you create a new VOIP line that there are selections for defining the gateway and direct media path.

Thanks for the help.

 

[tlpeter]

yes i mean a voip line
also don't asign more channels then the amount of vcm channel in the system

 

[tmckeown]

Thanks for the help. That gets me started. I think I have enough to at least start reconfiguring and testing.

 

[tmckeown]

hmmm
I'm still having some trouble. The systems don't talk to each other. I need some clarification again. I "think" the problem might be in my configuration of the VOIP line. Here is what I set them to. I'm sure you'll see this and be able to point out my error quickly.

I'm thinking that I don't have the gateway IP Address set correctly. What should it point to? Should it point to a gateway or to the IP address of the remote IPO system?

Do I need to create any short codes to tell each system how to find the other extensions? I'm thinking that the line setup does that, but I could obviously be wrong. So far, I have been all day.

Any help you can give would be great. It's very hard finding info on this. Dumb question: Is this a SCN? I've seen that term used a lot, but I am not able to fill in my missing knowledge.

Thanks,
Tom

 

[tlpeter]

you are just a few steps away from calling

the 412
you made a voip line with #10 (important)

incoming and out going line id are empty
also put there 10

the 406
the same as 412 (only line id 11)

if that is done you need to do one more thing

lets say that your number plan is 2000 till 2999 at the office with the 406

then in the 412 you have to make a shortcode

code: 2xxx
feature: dail
phonenumber: 2xxx
line id: 11

now it points to that line id that you have given
the 2xxx stand for 2 and 3 digits after that
if you have 2000 till 2200 and 3000 till 3200
you have to make two shortcodes
these shortcode are make in shortcodes of the system
don't make these shortcode's in lines

after a reboot you can see that the two ip offices are learning the other systems user etc etc
you can see this with monitor

and yes this a scn (small community network)

one error:
"Gateway" on the VOIP-tab should not be set to the local gateway, it should be set to the IPO in the other end.

 

[tmckeown]

Thanks for the replies.
One more question. The remote IPO does not have any duplicate names or extension numbers. But, I'm using numbers in the same range. Numbers in both locations are in the 200 series of numbers. Will I need to create 100 short codes to cover all 100 phones in the system? I was hoping that the system would just "learn" where the other extensions are.

Thanks again for the help both of you have given me.

 

[tlpeter]

what do you mean by 200 series ???
if extension 200 exists in the 406 and also in the 412 then you have a problem (it will be bigger if it is a scn)
if not then proceed
for a range of 200 till 299 you can make the shortcode 2xx (see other post)
the xx can be 00 till 99
so that covers all extensions in the 200 range

 

[Gibsonic]

tmckeown,

you must change the duplicate extension numbers. You can not use the 200 range on both systems if you want to connect them together. Think of the systems as one combined system and follow the rule that a single system would make you follow. You can't have duplicate names or extensions on a single switch, so you can't on a SCN either.

 

[tmckeown]

Sorry, I didn't clarify too well.

Extensions 201-210 are on the IPO406

Extensions 220-299 are on the IPO412

Is that OK?

Thanks,

 

[tlpeter]

oke then you have a little problem
then you have to make a shortcode for every extension
otherwise it will go wrong

 

[NuggiFirst]

It should work fine with those extension numbers!

I would use this setup:

Create an IP route for the other site
Now check that you can ping both IPO's from the remote sites.

Make a VoIP-line with the following settings:
Line number: Use a number that's different from the other lines.
Incomming/outgoing group ID: Again use an unused ID.
All channel settings: Set it to as many channels as available on the VCM.
Shotcodes tab: nothing.
VoIP tab:
Gateway: The IPO in the other end, NOT the local gateway!
Compression: Either G711 or G729 CS-ACELP
H450: H450
Silence suppresion: unchecked
Enable faststart: checked
Local hold music: unchecked
Local tones: unchecked
Out of band DTMF: checked if using G711, unchecked if using G729 CS-ACELP
Allow direct media path: unchecked
Fax transport support: checked.

Thanks for all the help. I was able to get the two systems to talk to each other. Yeah!

From reading and experimenting, it appears that if you set the VOIP line to "voice networking" you don't need to add any shortcodes. That works fine.

I do have a question about voicemail with a SCN. Per Avaya, they don't support multiple voicemail servers within a SCN. What is the common practice? I can see advantages both ways. If I turn off "voice networking" and add shortcodes, I can give the remote office their own voicemail, but it makes things a little trickier.

Are there standard practices for this? I'd like to get a few opinions.

Thanks,
Tom

PS: one problem that I have noticed: We have many people who switch phones often. The are setup as forced login users and login to whatever phone they are working at for the day. I notice That I can't get a phone in Chicago to login to the system in LA. Do you know if there is a way around it?

 

[tmckeown]

Nevermind about the PS. I found out it's a feature for version 4 that should come out this year.

So, the only question is whether to try and setup different voicemail servers for each system.

 

[tlpeter]

about shortcodes and scn
that should be the way but i have a side where shortcodes are nessesary (strange but true)
i'm glad it works

 

[tmckeown]

I'm very happy with the way it's working so far, with centralized voicemail. The only thing I wish we had was hotdesking over SCN. For now, at least we have a plan and a functional setup.

thanks for all the help you and other have given me on this.

About multiple voice-servers in SCN enviroment:

We have systems running with SCN enabled, and multiple VM Pro servers at different locations. We haven't run in to specific issues in this scenario. But as mentioned above, it's not supported by Avaya...
