Re: [SR-Users] Example kamailio.cfg t_check_trans()

Thanks, Daniel. I’ll update the docs to clarify this, if I get a moment. Cheers Phil *From:*sr-users [mailto:sr-users-bounces@lists.sip-router.org] *On Behalf Of *Daniel-Constantin Mierla *Sent:* 04 January 2016 08:06 *To:* Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.sip-router.org&gt; *Subject:* Re: [SR-Users] Example kamailio.cfg t_check_trans() Hello, On 31/12/15 12:39, Phil Lavin wrote: Hi there, The example config that Kamailio ships with contains this block of code in request_route: # handle retransmissions if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); I am not fully understanding the requirement for either of the t_check_trans() here. As far as I can see from the documentation, t_check_trans() returns a boolean value and does not modify any data internally. Can anyone help me find out what the relevance of the t_check_trans() calls is? t_check_trans() is used to detect retransmissions. If a retransmission is received, then the last reply (if any) needs to be sent back, then t_check_trans() does an 'exit' internally.
