[Kamailio-Users] How to add Retry-After header in 503 response

[Alex Hermann]

Hello,


is there a way to add a Retry-After header to a 503 response i'm sending out 
using t_reply?


Use case: t_relay creates an internal 408 on timeout. From failure-route, i 
want to pass it upstream as 503 with retry-after header. Changing the reply 
to 503 using t_reply works, but how to add the header?

The reply obviously doens't pass through any reply_route.
