Hi,
I have a question regarding CSeq of retried INVITE.
Consider the following scenario.
| INVITE(CSeq:1) |
|--------------------------->|
| |
| 18x |
|<---------------------------|
| |
| PRACK(CSeq:2) |
|--------------------------->|
| |
| 200 OK(PRACK) |
|<---------------------------|
| |
| 415 |
|<---------------------------|
| |
| ACK |
|--------------------------->|
| |
| INVITE(CSeq:2) |
|--------------------------->|
| with the same Call-ID |
| |
according to the section 8.1.3.5 in RFC3261, 2nd INVITE
"SHOULD have the same value of the
Call-ID, To, and From of the previous request, but the CSeq should
contain a new sequence number that is one higher than the previous."
therefore, I think the CSeq of 2nd INVITE SHOULD be "2".
Is my understanding correct?
Regards,
Shinji
