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

[Andrea Puddu]

Sorry guys, my results were not correct because I have tried to use a simulator.
Attached you can find a comparison between two different phones in the second scenario in a real case.
I guess that the first behaviour is not correct, isn't it?

Thanks everybody very much,

Andrea

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

 

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
