Failure to register a TE40 Highlighted

This post highlights a failure to register a TE40. Please see below for details.

Problem Description

Failed to register TE40

Analysis Progress

1. Get the SMC and TE40 IP address
   

2. Get the H.323 and SIP information of TE40
   

   On SMC

   

   

   On TE40

   

   

3. Checked whether the port of the TE40 side had been opened but can't be established.

   

4. Checked the SMC license
   

5. Checked the current alarm of TE40 on SMC to verify the issue. Below instruction is using TE20 as an example.
   

   Devices > Participants > “Endpoint” > Alarms > Current alarms

   Alarm that we get : Sip Registration Failure

   

6. Check the SC H.323 and SIP information
   

   Devices > Switch Centers > EmbededSC

   

7. Use the command below to check the port in the TE40 environment
   

   netstat-ano|findstr 5060
   

   netstat -ano|findstr 5061
   

8. Get the SC log & signaling diagnostic.
   

   1. Start Diagnosis
      

      Devices > SC > Embeded SC > Signaling Diagnosis > Start Diagnosis

      

      
      

   2. Register the TE40 again on SMC to get the error
      

   3. Get the Operation logs
      

      EmbededSC > Logs > Operation logs > Export

      

   4. Get the Device logs
      

      EmbededSC > Logs > Device logs > Export

      

   5. Get the Signaling Diagnosis
      

      Stop Signaling Diagnosis > Export

      

9. In the diagnostic, we can't find any information related to port 5061 (For TLS). Check the configured port on TE40 and found it using 5161. Changed it back to 5061.

   

10. From TE40 environment telnet to check the SMC environment whether opened the 5060 and 5061 port.
    

    Successfully telnet
    

    Command :
    

    telnet "GK address" 5060
    

    telnet "GK address" 5061

11. From SMC environment using putty to Telnet to check the TE40 environment whether opened the 5060 and 5061 port.
    

    Successfully telnet
    

    Host Name (or IP address) ="TE40 IP address"
    

    Port =5060 & 5061
    

    Connection type =Telnet

    

12. Get the information below again
    

    TE40 Signaling Diagnostics
    

    SC Signaling Diagnostics
    

    SC SIP information（Screenshot）
    

    At TE40 Side:
    

    Maintenance > Diagnostics > Signaling Diagnostics > Start
    

    At SMC Side:
    

    Details > SIP > Supprot TLS = “Yes”Note：
    

    If there is Support TLS = “No”, must change to “Yes”(If the endpoint is using TLS to register). To change the configuration, please refer the steps below. If the Support TLS = “Yes” by default, please proceed to Step (d)

    

    Edit > SIP > Support TLS =“Tick” > Yes
    

    Note: After edit must reboot

     
    

    

    Devices > Switch Centers > Embeded SC > Signaling Diagnosis > Start Diagnosis > “Register the TE40 again on SMC to get the error" > Stop Diagnosis > Export

    

    

    

    At TE40 Side:
    

    Maintenance > Diagnostics > Signaling Diagnostics > Stop > Download
    

13. After the  analysis, found an unknown IP address keep on sending the TCP.

    

14. Found the unknow IP address is TE40 Hotspot IP address and try to disable it. 

    System Settings > Network > Wi-Fi Settings > Wi-Fi Client = “Disable”

    

Root Cause

The TE40 Hotspot is opening, and the TE40 automatically using the hotspot IP address to register and it failed.

Solution Description

The TE40 had been successfully registered to SMC
