Hello, Razvan!
No, on the third leg the first instance doesn`t send 100 Trying to the Proxy. I made it because the Proxy is responsible for routing to another destination if INVITE cannot be sent to a main route in any case.
So as i understand i can only use
fr_timeout and fr_inv_timeout, right?--
Best regards, Denis.

Hi, Denis!,
According to the SIP RFC, if the Proxy doesn't receive any reply, it will not generate a CANCEL. Are you sending at least 100 Trying between your servers?
