Unhandled sip response for SIP INFO Event

[p-akshay]

Hello,

I am executing the following scenario:

1. User A sends INVITE to SIP Server ... both client and server are based on sipgo ... assume that the CSeq of this INVITE is 5
2. SIP Server forwards the INVITE to requested User B and upon receiving 200 OK, sends 200 OK back to User A
3. This transaction is concluded when SIP Server receives ACK from User A ... CSeq is still 5
4. Now, the SIP Server and User A want to exchange some information related to the call and use SIP INFO for this purpose...here the CSeq is used in increasing order (so initially it is 6, then 7 and so on)...also the SIP INFO shared was via call Dialog
5. When the other endpoint responds to SIP INFO with 200 OK, I observe the following error

transactionLayer > Unhandled sip response. UnhandledResponseHandler handler not added msg="response status=200 reason=OK transport=WSS

I think the expected behavior should be that the received 200 OK is accepted (as it is done in case of other sip events)

Let me know, if you need logs and any other info, i can add those separately

Thanks
