Subject: [SIPForum-discussion] IP 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..
