Re: [SR-Users] Avoiding script writer didn't release transaction warnings
Does Kamailio have a way to determine if to use the TM or SL module to send the reply? If yes, maybe the right solution is to modify the REGISTRAR sources to use it. I know OpenSIPS has a module called SIGNALING that allows exactly that. -Original Message- From: sr-users [mailto:sr-users-boun...@lists.sip-router.org] On Behalf Of Alex Balashov Sent: Monday, April 13, 2015 8:55 PM To: sr-users@lists.sip-router.org Subject: Re: [SR-Users] Avoiding script writer didn't release transaction warnings On 04/13/2015 01:54 PM, Alex Balashov wrote: Your interpretation is correct; an SL final reply within a context where a transaction exists will trigger the error.

Any idea?

When I receive a REGISTER, I create a transaction since I need to use the t_continue feature to wake up a suspended transaction. However, the save() command of the REGISTRAR module doesn't seem to call t_reply for replying the 200 (it looks like the SL module is used instead). Therefore, I get the warning every time it happens since the transaction is not released explicitly. Should I call t_release just before exiting the block handling the REGISTER?

Re: [SR-Users] Avoiding script writer didn't release transaction warnings
Your interpretation is correct; an SL final reply within a context where a transaction exists will trigger the error. A safe approach is: if(t_lookup_request()) t_release(); -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
Re: [SR-Users] Avoiding script writer didn't release transaction warnings
Kamailio has a send_reply() function that accomplishes this for manually issued replies, but that won't help with internally generated replies by the registrar, since these are automatic. As to a registrar patch, it's up to Daniel, but my personal opinion is that it's not practical to go through the code to patch everything sent SL just to make it more user-friendly in a transactional context where t_suspend/continue are used. Maybe the users should just deal. -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/ Sent from my BlackBerry.

Can you think of a case where one wants to reply stateless even if a transaction exists? -Original Message- From: sr-users [mailto:sr-users-boun...@lists.sip-router.org] On Behalf Of Alex Balashov Sent: Monday, April 13, 2015 9:06 PM To: Mickael Marrache Subject: Re: [SR-Users] Avoiding script writer didn't release transaction warnings Kamailio has a send_reply() function that accomplishes this for manually issued replies, but that won't help with internally generated replies by the registrar, since these are automatic.
