Issue Description
one customer site need to configure an sip trunk from eSpace U1980 to SBC, but failed with the prompt like below pic show :
Alarm Information
no
Handling Process
check the SBC configuration, it's not encryption, modified the sip trunk configuration on U1980 from TCP module to UDP module, it works fine.
Root Cause
this is because customer configured the sip trunk with TCP module, When it's TCP module , we have a license switch control called “Platform Open Interface license”, the TCP module is for encryption services, also should be the same with the SBC configuration.
Suggestions
need  to familiar with the difference between the TCP module and UDP module.
