Summary: b2b calls out of sync after server restart

Initial Comment:
If a server is restarted while a b2b call is active, the b2b call is restored from the db.
The issue is that subsequent in-dialog requests are having the Cseq reseted and this is causing rejections from the far end.

How to reproduce:
 - initiate a b2b call,
 - answer the b2b call,
 - send a reINVITE,
 - restart opensips,
 - send a reINVITE from one of the participants and check the CSeq number

It seems that the CSeq fields are not updated into the db.

Ovidiu Sas

Hi Ovidiu,

The code shows that the update function is called, but maybe there is
something with the query. Can you please investigate by watching the sql
query traces in your sql server?

Hi Ovidiu,

The db update function in b2b_entities modules does update the cseq -
check b2be_db_update function. And for reInvite this function should be
called by the b2b_prescript_f function. Please check in the logs which are
the messages printed for the processing of the reInvite ( note that in the
b2be_db_update a DBG is printed starting with b2be_db_update:UPDATED )

Regards,
Anca
