[OpenSIPS-Users] t_relay behavior with 477 send failed

[Bogdan-Andrei Iancu]

Hi Amit,

have you set the 0x02 flag for t_relay ? See:
       http://www.opensips.org/html/docs/modules/1.6.x/tm.html#id293378

This flag will prevent the t_relay() function do internally deal with 
errors (by sending back a negative reply).

Regards,
Bogdan
