Hi Klaus,

PRACK is processed as any other request, nothing special.

Is the retransmission hitting the same process as the original request? how was the PRACK originally handled ?

PRACK is handled like all other in-dialog requests:

if (loose_route()) { ... some NAT checks for INVITE... if (!t_relay()) { sl_reply_error(); } }

The strange thing is that the first PRACK is forwarded by t_relay, but the retransmission generates the error.

I have checked the retransmission: it is exactly the some message as the first PRACK.

Hi!

I have encountered this problem at an openser 1.1.1 proxy:

Client Proxy Client

---PRACK------> ------PRACK----->

retansmission -----PRACK------->

here at this point (when openser receives the PRACK retransmission) t_relay fails:

ERROR: t_newtran: transaction already in process 0xb66e7880

Is this a known problem? Were there some fixes to 1.1 or 1.2 branch?

regards klaus

Hi Bogdan!

I could reproduce the t_relay error also with an in-dialog BYE request.

The problem is only triggered if uac_replace_from is used when setting up the call. uac module is used in automatic mode.

client proxy client ---------INVITE-------> uac_replace_from() ----------------------> <-------200 OK--------<----------200ok-------- -------ACK------------->--------ACK----------->

-----BYE-------------> --------BYE----------->

retransmission --------BYE----------> ERROR: ERROR: t_newtran: transaction already in process
