How to Connect Cisco Unified Call Manager to Yeastar TG800

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.


  • Make outbound calls from CUCM via the GSM trunks of TG800 directly.
  • Receive calls from GSM trunks of TG800 at CUCM.


  • IP address of CUCM:
  • IP address of TG800:

                                                                          Figure 1

Please make sure Cisco CallManager Service is activated on CUCM.
Steps to activate Cisco Call Manager:

1. Log in to the CM Administration Web interface.

2. In the field “Navigation” on the top right corner, select Cisco Unified Serviceability and click Go.

3. Under Tools click Service Activation.

4. Check if the Service “Cisco CallManager” is activated.

2. Connect CUCM to TG800

2.1 TG800 Configuration

Step 1: Create one Service Provider SIP trunk on TG800, connect it to CUCM.
Path: Gateway--VoIP Settings--VoIP trunk--Add VoIP Trunk

                                                                             Figure 3

Save and apply the changes, we can check the status of this trunk, it should be OK (green).
Path: Status--System Status--Trunk Status

                                                                          Figure 4

2.2 CUCM Configuration

Step 1: Configure the SIP Trunk Security Profile

1) Go to SystemSecuritySIP Trunk Security Profile

2) Click Add New.

3) Configure the fields as follows:

Note: Please change the “Outgoing Transport Type” to UDP, otherwise the outgoing calls would fail.

                                                                             Figure 5

4) Click Save.

Configuration on Version 9.X

In version 9.x, the Non Secure SIP Trunk Profile already exists, but it must be modified.
1)On Unified CM, go to SystemSecuritySIP Trunk Security Profile.

2)Select Non Secure SIP Trunk Profile.

3)Modify the fields as follows:

                                                                                  Figure 6

4)Click Save.

Step 2: Configure the SIP Profile

1) On Unified CM, go to Device--Device Settings--SIP Profile.

2) Click Copy against the Standard SIP Profile.

3) Check “Allow Presentation Sharing using BFCP” if BFCP (Dual video / presentation sharing) is required. Check “Use Fully Qualified Domain in SIP Requests” if needed,
leave everything else as it is:


                                                                                      Figure 7
4) Click Save.

Step 3: Configure the SIP Trunk device

1) On Unified CM, go to DeviceTrunk.

2) Click Add New.

3) Select a Trunk Type of SIP Trunk.

                                                                                     Figure 8
4) Click Next.
5) Configure the Device Information fields as follows:
Mark the field modified compared with default settings.


                                                                                      Figure 9
6) Click Save.

7) Click Reset.

Step 4: Configure Route Pattern for the SIP Trunk.

1) On Unified CM, go to Call RoutingRoute/HuntRoute Pattern.

2) Click Add New.

3) Configure Route Pattern as follows:

Note: Set Route Pattern to 9XXXXXXXXXXX, which means all 12-digit calls starting with 9 will be sent to Yeastar via this SIP Trunk. Besides, you can set up multiple Route Patterns for a SIP trunk.

                                                                                  Figure 10
4) Click Save.

Step 5: Check the status of this trunk.

On Unified CM, go to Device--Trunk, click Find.

                                                                            Figure 11 

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.
