Hi,

I have added a huristics table to SUA as SCCP has and made RANAP register to it which hopfully solves the RANAP case.

Hi,

 

Is there any plan to support SSN-less RANAP over SUA?

I assume the problem you're talking about is the fact that the SUA CODT
payload doesn't get dissected as RANAP?

In that case the problem is that the RANAP dissector is called based on
SSN and the SSN is not present in SCCP DT or SUA CODT messages. The
SCCP dissector was updated by LEGO (rev 16783) to overcome this problem
by tracking SCCP-Class2 connections (in a conversation-like structure)
so SSN-less messages still call the SSN-based upper lay dissector.

SUA could also have this feature but it doesn't so far.

Regards,
-Jeff
