[SIPForum-discussion] IP Media 3000 generating BYE message

[Halit Sakca]

Hi Guys,

You shouldn't go to wrong direction. Its ISDN message.
its not 318 its hex so its actually 01/3e ->"inconsistency in designated outgoing access information and subscriber class".

Well, for this matter we need to get more investigation like media server log, it could be either media server bug or missed configuration.
Ashoke is it CMS (convedia)? if so pls provide logs during the failure scenario from web gui. its protocol log.

sorry, I wish I could help more.
BTW pls provide whole network trace not one side.
Selamlar,
Halit Sakca

Media 3000 generating BYE message



 



Hi Guys,





 





I am handling a application server which provides prepaid
service. We are using IP Media 3000 for playing announcement and digit
collection. The call flow between application server and media server is like this.





 





AS           
               
        MS





---------------INVITE----------------->





<---------100 TRYING--------------





<-----------200 OK-------------------





----------------ACK------------------->





----------------INFO------------------>





<----------200 OK--------------------





 





<--------------INFO-------------------





--------------200 OK---------------->





----------------INFO----------------->





<------------200 OK-----------------





 





<--------------INFO-------------------





---------------200 OK--------------->





----------------BYE------------------>





<-------------200 OK----------------





 





 





We were trying to divert some TDM network traffic through
application server. But got stuck with an issue of call failure. After investigation,
we found that on certain occassion, Media Server is sending BYE message at some
stages. But we are not able to understand why BYE message is being sent my
Media Server. As per the call flow, media server never would generate a BYE
message. Moreover, it is sending a 200 OK against the previously sent INFO from
AS.





 





I am attaching sample trace of a call between the
application server and media server. Please note that I could capture only the
messages from media server to application server. Can anybody help me
understand why this BYE message is being originated. Also I have noticed Cause
318 Q850 being mentioned in all the BYE messages. But I could not find this
release cause in Q850. Any idea what is this release cause.





 





 





Best Regards..
