application-context-name in tcap .. how to read

Hi,

    I trying to integrate my IN with msc for INAP call.... but in tcap
diaglouerequest in IDP i am geting below error in my ethreal trace

dialogueRequest

protocol-versionrq: 80 (version1)
application-context-name: 0.4.0.1.1.1.0.0 (ccitt.4.0.1.1.1.0.0)
BER Error: Wrong field in sequence  expected class:0 (UNIVERSAL) tag:6(OBJECT IDENTIFIER) but found class:2(CONTEXT) tag:0
after application context-name only i am getting BER Error .. so is it due to any wrong protocal version they are sending from msc side

or how can can i read from 0.4.0.1.1.1.0.0  msc is sending inap protocal can you please guide

Hi,
Do u have ASN decoder? This tool will help you to see the all TCAP messages in MSC side?
Then you can change the corresponding application-context which is used by IN

Hi
Looks like in SCCP portion of the msg Protocol class is coming as 2 and ur expecting a 0 Protocol class.
decode ur hex dump with linkbit.com so that u ll find where it is going wrong.
