Hi,

I had a setup with an old version where I used the function t_relay_to("0x02").
Following the 3.1 documentation, flag :
牋牋 0x02 - do not generate reply on internal error (NOTE: has no effect anymore)

I used that function as a workaround with a pbx that stop to register when it receive an error response like
478 Unresolvable destination or 408 request timeout.

I did upgrade to 3.1 to have dns srv caching.

Do you know how this would be possible with kamailio 3.1.

Thanks for your suggestions,
hp
