Troubleshooting a generic error code 50 on WDE

[Gef Buneri]

Hello all, hope everything's ok out there. I'm trying to troubleshoot a very rare and randomic "generic error 50" on certain WDEs. Any clue? this points are relevant, to me, but where to look at any doc that could help me out? (Reason: SIP;cause=408;text="timeout-ST" and Request rejected: error code 237)

Maybe some calls are arriving without SDP? Or in wrong expected message?

[Gef Buneri]

Hi Cav! it seems that SDP error is present in any call, even OK ones.

[hsujdik]

I see that your EventError has a Request associated. What was the request that the SIP Server client (WDE) sent? Look on the log file backwards for the "AttributeReferenceID 83" that is before the EventError (not always 83, only in that example because it is the sequential ID of the request performed by the client).
It probably could be some RequestSendDTMF, RequestSingleStepTransfer, RequestInitiateTrasnfer, RequestAnswerCall, RequestHoldCall... anything like that?

Also, are always the same DNs that randomly have this error? Or are they random?

[Gef Buneri]

Hello Hsujdik, IDs are random, here's a bunch examples.

AttributeReferenceID 25
AttributeReferenceID 18
AttributeReferenceID 64
AttributeReferenceID 67
AttributeReferenceID 9
AttributeReferenceID 13

All DNs receiving that call flow, from that specific number, experience this error; It's for sure something related to the SBC in front of the SIP Server, but I really can't figure anything from SIP Server's logs.

Check the SDP You will see some difference or where the SDP comes in (invite or ACK)
