Hi,
A question about CSeq numbers in SIP transactions is
- is it necessary for the CSeq for increase monotonically
from INVITE to BYE or can a BYE have a CSeq that is lesser
than that of the last (re)INVITE.
eg.
A B
| |
| |
|<---------INVITE-------|
|---------100---------->|CSeq=101INVITE
|---------200OK-------->|
|<---------ACK----------|
| |
| |
|---------INVITE------->|
|<--------200OK---------|CSEQ=102INVITE
|---------ACK---------->|
| |
| |
|---------INVITE------->|
|<--------200OK---------|CSEQ=103INVITE
|---------ACK---------->|
| |
| |
|<--------BYE-----------|CSEQ=102BYE
| |
| |
Is this legal or should the CSeq be 103BYE ?
Thanks and Regards
Sharath
