Hello, dear!
Good day to you!
This article describes how to solve the problem that some H.323 terminals cannot register with the SC after the SC is newly installed.
Problem Description
After the SC is newly installed, some H.323 terminals cannot register with the SC.
The H.323 terminals include terminals and MCU.
SC version: V600R019C10SPC910
Handing Process
Analyze the packet capture logs. The error code 4001H is found, and the error code of the SC is 0x00040001, that is, the GK rejects the registration request of the H.323 terminal.
Analyze the SC logs.
It is found that the encryption algorithm of H.323 terminals is not SHA1 but the current SC supports only SHA1. Therefore, the SC rejects the registration request and some H.323 terminals fail to register with the SC.
Root Cause
Since V600R019C10SPC910, the newly installed SC supports only SHA1 encryption. As a result, some H.323 endpoints fail to register.
Solution
Log in to the SC via SSH, the port is 122.
Run the system-view h323-config h323-support-auth-algorithm 2 command to enable the SC to support SHA1 and MD5.
Run display h323-config to check the result.
Register the terminal with the SC again.
