1. Introduction
This application note shows how to connect CUCM to TG800 via SIP trunking. In this guide, we will take TG800 as an example; the same configuration will apply other TG series products.
Target:
- Make outbound calls from CUCM via the GSM trunks of TG800 directly.
- Receive calls from GSM trunks of TG800 at CUCM.
Description:
- IP address of CUCM: 192.168.10.200

3. IP to Mobile
In this section, we will configure outbound call from CUCM through TG800.
3.1 Create Mobile Group on TG800
There are multiple GSM channels installed in TG800 for outbound calls.
Here is an example:
Customer wants to dial external numbers on CUCM side through TG800 directly, TG800 should route the call via the GSM trunk which is least used.
Path: Gateway--Mobile List---Mobile Group
In this example, we need to choose all GSM channels to right side, as for strategy, we can choose “Balance” mode.
Figure 12
Save it and apply the changes.
3.2 Create “IP to Mobile” Route
Path: Gateway--Routes Settings--IP to Mobile
Figure 13
Simple Mode: No
Choose “Simple Mode” to “No”, you will see the advanced settings.
Call Source: SPS-CUCM
Call Destination: Mobile Group--All_GSM
The default setting “X.” for “Outbound Dial Pattern” allows users to make any external number out without restriction.
Save it and apply the changes, then you can dial outbound calls from CUCM via TG800 directly.
4. Mobile to IP
In this section, we will configure incoming call to CUCM through TG800.
4.1 Create a “Mobile to IP” Route on TG800
Path: Gateway--Routes Settings--Mobile to IP
Figure 14
Simple Mode: No
Choose “Simple Mode” to “No”, you will see the advanced settings.
Call Source: Mobile—GSM1. You can select any GSM line or mobile group. Here we select GSM1 as an example.
Call Destination: SPS-CUCM. All the calls from GSM1 will be sent to CUCM via this trunk.
Hotline: 9456. You can enter the number as 9456 in this field, which is a extension (Directory Number) on CUCM.
4.2 Make a Call to CUCM through TG800
Now we can test incoming calls for CUCM. If you dial the GSM1 number on TG800, the call will be routed to the extension 9456 on CUCM.
Note: If there is no "Hotline" set for "Mobile to IP" route on TG800, when you dial the GSM trunk number on TG, a ring tone will be heard after the call is connected. Then, you dial the number to reach CUCM.
