[SR-Users] T_precheck_trans

[Daniel-Constantin Mierla]

Hello,

given that this question was asked few times in the past, I put it in
the FAQ:

  -
https://www.kamailio.org/wiki/tutorials/faq/main#how_is_the_sip_request_retrans

Hope the explanation there is clear enough, if not ask more here and I
will complete with further details.

Cheers,
Daniel
