How to Connect 2 Trixboxes with IAX2 Trunks

This is how GSnover taught me how to do this:

Here is an IAX2 trunk that we are using right now:

Outgoing Settings:

Trunk Name: Plasma-Peer

Peer Details:
allow=speex
disallow=all
host=66.197.221.49
secret=VoIPIsMyFriend
type=peer
username=Plasma-User

Incoming Settings:

User Context: Plasma-User

User Details:
allow=speex
context=from-internal
disallow=all
host=66.197.221.49
secret=VoIPIsMyFriend
type=user

On the other machine, set up the trunk identically, except put the public address of YOUR TB in their definition - so they are looking at you and you are looking at them - the host= line.

Once this is done, you still have to have some sort of dialplan rules to accept traffic from them or direct traffice to them - easiest is just an outbound route that says the following:

Our TB - we use extensions 14xx, and Plasma uses extensions 3xx, so my outbound route is:

Plasma

Pattern:

3xx

Trunk:

Plasma-Peer

On his end, he would call the route Barking Dog, so

Barking Dog

Pattern:

14xx

Trunk:

Plasma Peer

Giving the user the context of from-internal gives them the ability to use your lines - if you just want intercom and transfer, set the context to from-pstn. Now, you have intercom and transfer ability between sites. To make a call ringing into one location ring at another, you either need to modify the dial plan (hard), or set up Miscellaneous Destinasions (easy) and then create an inbound route to point to the Misc. Dest. Set your FIrewall/Router to forward UDP port 4569 to the IP of the TB on both subnets, and you should be in business.

All circuits are busy now, please try again later.

Any other ideas?

Box 1 (Free Pbx 2.2.3)

Trunk Name: ToVoip2
Peer Details
allow=speex
disallow=all
host=xxx.xxx.xxx.138 (xxx's are the actual IP of box2)
secret=12345
type=peer
username=trixboxb

User Details:
allow=speex
context=from-internal
disallow=all
host=xxx.xxx.xxx.138 (xxx's are the actual IP of box2)
secret=12345
type=user

Outbound Routes
Route Name: ToVoip2
Dial Patterns: 2XX

Box 2 (Free Pbx 2.3.1.3)

Trunk Name: ToVoip
Peer Details
allow=speex
disallow=all
host=xxx.xxx.xxx.205 (xxx's are the actual IP of box1)
secret=12345
type=peer
username=trixboxb

User Details:
allow=speex
context=from-internal
disallow=all
host=xxx.xxx.xxx.205 (xxx's are the actual IP of box1)
secret=12345
type=user

Outbound Routes
Route Name: ToVoip
Dial Patterns: 1XX

Only 1 IAX trunk on each box

Several Sip trunks on Box 1 and 1 Sip trunk on Box 2

I am trying to give myself some redundancy....

Truly appreciate the help.

On your original setup

"All circuits are busy now" indicates it was trying to get an outside line but could not find a route.

and "cannot complete call as dialed" indicates it was trying to dial an extension that did not exist or could not find.

I am assuming you are on the same LAN as a test.
As a test I would put in GSnover's example verbatim except for the host=
This worked in our shop, then we just modified it to suit our criteria.

I will be gone for a short time. Let me know what happens.

Hi Guys;

Thanks for all of your help. I have tried everything markwho suggested then tried cosmic wombats suggestions, as per the link.

A little more information, both boxes have public IP's and are fully open to each other and the world.

Again......help, aider moi, au secours...........

Hello All;

I finally got this puzzle working properly! I think it was an error on my part assuming that the "trunk name" had nothing to do with anything when in fact it would appear that it does.

Anywhoo just wanted to thank everyone for their help and I would be glad to post my settings if anyone requires.

Cheers

Box "A"

Trunk Name:voip2

context=from-internal
host=xxx.xxx.xxx.138 (Box "B" Public IP)
secret=123456
trunk=yes
type=friend
username=voip1

User Details: EMPTY

Register String: voip1:123456@xxx.xxx.xxx.138 (Box "B" Public IP)

Box "B"

Trunk Name:voip1

context=from-internal
host=xxx.xxx.xxx.142 (Box "A" Public IP)
secret=123456
trunk=yes
type=friend
username=voip2

User Details: EMPTY

Register String: voip2:123456@xxx.xxx.xxx.142 (Box "A" Public IP)

With this config I am able to connect to 2XX extension on Box "B" from 1XX etensions on Box "A" and vice versa.

I am also able to reach outsde trunks on Box "A" from extensions on Box "B".

For anyone with this config, make sure you have outbound routing correct, so box B will look out to the box A trunk, or vice versa, depending on your config.

I followed this and it worked 100% - i can now trunk between two boxes.

Question: what is "Incoming Settings" used for then? I've got it blank and we can call from either side, so when would this be used?

Tommaso,

This is how I have mine setup.

BoxA (has FXO card)
Outbound Route
Dial Patterns:
011.
1NXXNXXXXXX
1XX
5|XXX (this is for my intertrunk dialing)
NXXNXXXXXX
NXXXXXX

Trunk Sequence (I have 4 FXO card)
ZAP/1
ZAP/3
ZAP/4
ZAP/2
IAX/voip2

BoxB (IAX Trunk Only)
Outbound Route
Dial Patterns:
011.
1NXXNXXXXXX
1XX
5|XXX (this is for my intertrunk dialing)
NXXNXXXXXX
NXXXXXX

Trunk Sequence
IAX/voip1

Hope this help.

destination - this is where Miscellaneous Destinations come in - create one for the extensio you want the IVR to be able to hit, and then it can be a destination referenced by the IVR.

Greg

and then a Dial-Plan route that says if it sees 3xx, use the IAX2 trunk and ge the extension there.

Greg

I followed this thread and I have an IAX trunk between 2 TrixBox systems. I can call each extension from A to B and B to A no problems. I can make calls from the B system through the A systems PRI trunk as well. What I can't figure out is how to make incoming calls route to the B system ? My A system has extension 2X and My B system has extension 3X . If I call my primary number on the A system the A system does not know how to reach the 3X extensions I get a message indicating and invalid extension. Can anyone give me an idea what I need to do in order to accomplish this ? What I want to do is be able to route a specific DID to the B system. I am not sure if the misc destination is the only method to make this work.

Thanks

Hi Guy both the server connect but no audio why?

New Update

There one way audio why?

Thank

i have 2 TB servers

Second TB Configuration to connect to First
Create a new IAX2 Trunk
Trunk Name: Server1
Peer Details:
context=from-internal
host=192.168.1.66

my 1st Problem :
when i call any one from server 1 to server 2 the callerID appear that 222
and from server 2 to server 1 the callerID appears that 111
i want to know why is that happen and how i can change the callerID to the user ID what i mean i want that when i call user 1001 from user 2001 the callerID which appear 2001 not 111
and when i call 2001 from user 1001 the callerID which appear 1001 not 222
how i can do that .

my 2ndproblem :
when i call from server 1 to server 2 or vice versa i can hear 4 or 5 rings with caller before the receiver ringing how i can stop that i want it ring with the double sides in the same time with no latency .

my 3rd problem :
we re using the lan ip to access to the server right i want to have an public static IP but dont allow any one to access to my page accept my public static ip and lan ip
what i mean i want to make a public static IP to my TB but i dont want any one to access TB accept me . how i can do that and i dont want to show my page as a restricted area or show its user name and password requirements "i dont want to show the window of user name and password"
i want to stop accessing the web page from public static IP and access it from lan ip or from my public static IP my ip only

my 4th problem :
how i can setup any FXO card and how i can it ? and how i can know the channels ?

my 5th problem :
i want to connect mt TB with a PRI line that is landline which have 30 Separated lines
which hardware which ill need and how i can make calls through them . i want to make every line from the 30 lines have its trunk and dial pattern . i hope any body can help me and what is the configuration will needed ?

details about platforms :
TB v2.6.2.1
processor 3GHz
Ram 1G
FXO cards : openvox A400P02 & digium 1TDM402BF
