Kamailio -can we change 478 to 503 when dns fails?
Hello there, Some times dns server fails and my kamailio server start replying "Unresolvable destination (478/SL)". The propose of my email is to know if is there any possibility to change this reply (478) to for example one of 5XX replies. I have modparam("sl", "default_code", 503) but in situations where dns fails, kamailio doesn't reply 503. Thank you for your support Regards José Seabra
Hello, are you using forward() or t_relay() to send out? Cheers, Daniel On 28/02/2017 12:32, José Seabra wrote:

Hello, so it seems that the error happens before the transaction is created, as I see SL in the response... Can you try with: https://www.kamailio.org/docs/modules/stable/modules/tm.html#tm.f.t_set_disa... before t_relay() and then catch the failure execution with if(!t_relay()) and send there response you want there.

before t_relay() and then catch the failure execution with if(!t_relay()) and send there response you want there.
