[SIPForum-discussion] Which should be the correct behaviour?

[Herve Jourdain]

Hi,

 

I would only add that it’s likely that SIP phone receives D1 487 Request
Terminated


 

Regards,

 

Hervé

Both are not correct scenario.  Sip phone MUST not send CANCEL without
receiving any Provisional response response. If CANCEL is sent after
receiving any provisional response, then Scenario 1 is correct.

Hello, 

does anybody know which should be the correct phone behaviour in these two
scenarios?

-          Scenario 1:

SIP phone sends an INVITE (D1)

SIP phone sends a CANCEL (C1)

SIP phone receives C1 200 OK 

SIP phone receives D1 200 OK 

 

-          Scenario 2:

SIP phone sends an INVITE (D1)

SIP phone sends a CANCEL (C1)

SIP phone DOES NOT receive C1 200 OK 

SIP phone receives D1 200 OK

 

Thanks,

 

Andrea
