How to integrate TG with AVAYA IP Office

Integrate a TGXX series on a AVAYA IP 500 V2 System phone .

All TG series settings and GUI are the same, and here I make TG200 as the example. I have a SIP

trunk channels license 5 in my Avaya, so I can create the SIP trunk (without registration, but point to point) between TG and Avaya.


Avaya IP Office 500V2 Control Unit IP Address:

Yeastar TG IP:

All TG has an ip address on the range 192.168.5.X,therefore you must set the IP Office in the same subnet mask, here my IP Office’s address is


Note : Before this integration, please make sure there is a SIP Trunk Channel license in Avaya IPO500v2.

1.Create a VOIP trunk in Avaya

1.1.Set IP addr of TG ( in the blank of ITSP Domain Name.

Path IP Office System : Line >Right Click > New > SIP Line


1.2.Add a new SIP URI in this new SIP line, those settings in this URI are default settings, Here we need to note the Incoming group number and outgoing group number. (Here they are 3)

Path IP Office System : While on the SIP Line screen,click on the Tab SIP URI.

2.Create a VOIP trunk (Service Provider) in TG device


In the Hostname/IP fied,make sure you put the AVAYA’s IP address, Trunk type must be “Service Provider ”

After creating this VOIP trunk in the TG device, you must check the connection between the AVAYA and the TG, go status Tab ,trunk status to verify if everything is ok.

Path TG : Status >> Trunk Status

Since a VOIP trunk has been created between the AVAYA and the TG,then these both can see each other ,we need to configure right now, the incoming call as well as the outbound call.


3.First, let’s create a Mobile Group on TG.

Path TG : Gateway >> Mobile list >> Mobile Group,

It ’s to group the existing GSM on a single group,here I have two GSMs (1-2) since I use a TG200,the Strategy could be either Sequence or Balance, here I choose “Sequence” . Also move all the existing GSM to the selected field,if you want to create multiple groups, you can break the group members onto different groups, here I create one group so I selected the two existing GSM. For the group name field,you must give a name. Here is : ALL_GSM

4.So now let’s set up both systems so users can receive call and can make

outbound call as well.


4.1.First ,Create a Mobile to IP on the TG devie.

Path TG : Gateway >> Routing setting >> Mobile to IP

Simple Mode : No

Route Name : TG_to_AVAYA

Call Source : Choose the mobile Group created previously (All_GSM)

Call Destination :Choose the service provider that we created : SPS – AVAYA

Hotline : Here I put an Xtension number that is registered in ip office system, for those whith some knowledge in AVAYA,this Xtension could be either an Xtension number or a Huntgroup number.

Strip : Leave as default. 0.

4.2.Now We need to create in incoming call on AVAYA ip Office system.

First let’s create an ARS on the IP office system. (It’s very IMPORTANT)

IP Office path: ARS >> Right Click >> New


In the Route name fiel, give a name for this route, here is “Debut” make sure that the secondary and check user call baring are checked, these two options are optional it will help for futher config. At the bottom you need to create a shord code,click Add.

Code : XN; It will accept any code you will created on the Short code Option between 0-9

Feature : Dial

Telephone number : N;

Line group : 3, this is the group created on the SIP Line

Now let’s create an Incoming call on .

Path Ip office : Incoming >> Right click >> New

While on the Standard Tab, the Bearer Capability must be Any Voice.

Line group ID : 3 , the group id created in the SIP Line .Leave all the rest as default.

Now clik the Destination Tab , and pick up the extension number 101, the same xtension that we put in the TG whe creating an Mobile to IP

Save and make an inbound call, you will see that this Xtension ring.


4.3.Now let’s give users acces to make outbound call using the trunk.

First we must create an IP to Mobile on the TG devide.

Path : Gateway >> Routing setting >> IP to Mobile.

Simple mode : No

Route Name : AVAYA_to_TG

Call source : SPS – AVAYA

Call Destination : Mobile Group – ALL_GSM

Two Stage Dial : No,if you choose Yes,users will need to compose two digit before dialing out,e.g (88 Plus phone number -99 Plus phone number -00 Plus phone number) , here we do it simple,so users will press only one number berfore dialing out e.g (8 Plus phone number -9 Plus phone number -0 Plus phone number).


4.4.Now let’s create a shortcode on IP Office ;

Path IP Office : Shortcode >> Right Click >> New

In the Short code tab,

Code : 8N ,so users will press 8 before dialing out, you can put any number between 0-9, (XN; remember this code previously created).

Feature : Dial

Telephone Number :N

Line Group ID : 51:Debut

(this code :( 51:Debut) is from the ARS we created,).

Let’s make an outbound call, from any phone registered In IP Office (Analog,Digital or IP) just press 8 , you will have a dial tone ,now you will be able to dial out.

    Okay, i pretty sure you have installed the 3rd party SIP trunk licence on IPO.

    What model TG Neogate you work with  ?

    There is a default route on TGXX series for outbound and inbound calls,you must delete them  and create your own route, also on IPO system you need to create the short code that allow you  to make outbound call via TG GSM Gateway.


    Please follow the instruction and review your configuration , it always work for me. 


    Thanks !
