How to Connect Cisco Unified Call Manager to Yeastar TE

1. Introduction

This application note shows how to connect Cisco Unified CallManager to Yeastar TE gateway via SIP trunking. This guide has been tested with Yeastar TE100 and CUCM version: 8.6.2.


After connecting Yeastar TE100 and Cisco Unified CallManager, physical E1 trunk will be extended on Cisco Unified CallManager.
The following features can be achieved:

  • Make outbound calls from CUCM via the E1 trunks of Yeastar TE100.
  • Receive calls from the E1 trunk of Yeastar TE100 at CUCM.


  • IP address of CUCM :
  • IP address of TE100 :
  • A E1 trunk from provider is connected to TE100.
  • E1 DID range: 5551000-5551099


2. Preparation

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.

3.Connect CUCM to Yeastar TE100

3.1 Configuration on TE100

Step 1. Create a SPS trunk on TE100 to CUCM.

Path: Gateway--VOIP Settings--VOIP trunk--Add VOIP Trunk.

                                                                              Figure   2

  • Trunk Type: Service Provider
  • Provider Name: CUCM
  • Hostname/IP

Step 2. Check the status of this trunk.

After creating the SIP trunk, we can check the status of this trunk, it should be OK(green).
Path: Status--System Status--IP Trunk Status

                                                                               Figure   3


3.2 Configuration on CUCM

Step 1: Configure the SIP Trunk Security Profile

1)Go to System--Security--SIP Trunk--Security Profile
2)Click Add New.
3)Configure the fields as follows:
Please change the “Outgoing Transport Type” to UDP, otherwise the outgoing calls would fail.

                                                                              Figure  4

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   5
4)Click Save.

Step 2: Configure the SIP Profile

1)On Unified CM, go to DeviceDevice SettingsSIP 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    6

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    7
4)Click Next.
5)Configure the Device Information fields as follows:
Mark the field modified compared with default settings.



                                                                                 Figure   8
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:

Set Route Pattern to 5XXXXXX,which means all 7-digit calls starting with 5 will be sent to TE100 via this SIP Trunk.
Besides, you can set up multiple Route Patterns for a SIP trunk.

                                                                              Figure   9
4)Click Save.

Step 5: Check the status of this trunk.

On Unified CM, go to DeviceTrunk, click Find.

                                                                            Figure   10


4. Incoming Calls from E1 to CUCM

In this section, we will configure incoming calls to CUCM.

Create a route from TE100 to CUCM.
Path: Gateway->Route Settings->Route List->Add New Route.

                                                                                   Figure    11

  • Simple Mode: Yes
  • Call Source: Trunk—E1Trunk1.
  • Call Destination: ServiceProvider-CUCM. 
  • Strip: 7, in order to translate the call to CUCM’s extension, we stip the original DID first.
  • Prepend these digits: 9456, a extension number on CUCM

All the calls from E1 trunk will be sent to CUCM via SPS trunk.


5. Make External Calls from CUCM via E1

In this section, we configure outbound calls for CUCM’s extensions.

Step 1: Create an outbound route from CUCM to E1 on TE100

Path: Gateway->Route Settings->Route List -> Add a New Route

  • Simple Mode: Yes
  • Route Name: From_CUCM
  • Call Source: ServiceProvider--CUCM
  • Call Destination: Trunk—E1Trunk1

                                                                               Figure     12

Step 2: Set DOD for CUCM extension.

For example, extension 9456 will use E1 DOD 5551000 to make outside calls via E1.

                                                                            Figure    13

Step 3: Make test calls.

After settings, all the calls from CUCM will be routed to E1.
