Re: [sr-dev] [kamailio/kamailio] CSeq issues with CANCEL after INVITE (#918)

Now the CSeq is correct, however I do see repeated CANCELs and 487s from the peer just as in https://github.com/kamailio/kamailio/issues/870 This means that it does cancel the call and these extra messages back and forth do not cause any end-user side effects: # U x.x.x.50:5060 -> 85.14.79.130:6050 INVITE sip:48732406302@provider.server:6050 SIP/2.0.
